APRIL 30, 2010

Dear Shareholder

Although overall global economic and financial conditions have generally improved over the past year, the period ended with high levels of market
volatility and diminishing investor confidence sparked by the sovereign debt crisis in Europe, concerns over the strength of the economic recovery
and uncertainty surrounding the future of interest rate policies. Additionally, as the period drew to a close, the increasing likelihood of more stringent
financial market regulations added to the overall sense of investment uncertainty. Despite the uneven nature of recent market conditions, we continue
to believe that the “Great Recession” likely ended at some point last summer, thanks primarily to massive fiscal and monetary stimulus, and that the
global economy remains in recovery mode.

Global equity markets bottomed in early 2009 and since that time have moved unevenly higher as investors were lured back into the markets by
depressed valuations, desire for higher yields and improvements in corporate earnings prospects. There have been several corrections along the way
and volatility levels have remained elevated — reflections of mixed economic data, lingering deflation issues (especially in Europe) and uncertainty
surrounding financial regulations. On balance, however, improving corporate revenues and profits and a positive macro backdrop helped push stock
prices higher over the last twelve and six months. From a geographic perspective, US equities have outpaced their international counterparts in recent
months, as the domestic economic recovery has been more pronounced and as credit-related issues have held European markets down.

Within fixed income markets, yields have been moving unevenly as improving economic conditions have been acting to push Treasury yields higher
(and prices correspondingly lower), while concerns over ongoing deflation threats have acted as a counterweight. As the period drew to a close,
Treasury yields were falling as investors flocked to the “safe haven” asset class in the face of escalating uncertainty. Over the course of the last twelve
and six months, however, Treasuries underperformed other areas of the bond market, particularly the high yield sector, which has been benefiting from
increased investor demand. Meanwhile, municipal bonds slightly outperformed taxable sectors over both the six- and twelve-month periods thanks to
continued high demand levels, but have continued to face the headwinds of ongoing state and local budget problems. As in the taxable arena, high
yield municipals have been outperforming the rest of the market.

Regarding cash investments, yields on money market securities remain near all-time lows (producing returns only marginally above zero percent), with
the Federal Open Market Committee reiterating that economic circumstances are likely to necessitate an accommodative interest rate stance for an
“extended period.”

Against this backdrop, the major market averages posted the following returns:
Total Returns as of April 30, 2010	6-month	12-month
US equities (S&P 500 Index)	15.66%	38.84%
Small cap US equities (Russell 2000 Index)	28.17	48.95
International equities (MSCI Europe, Australasia, Far East Index)	2.48	34.43
3-month Treasury bill (BofA Merrill Lynch 3-Month Treasury Bill Index)	0.04	0.15
US Treasury securities (BofA Merrill Lynch 10-Year US Treasury Index)	(0.54)	(1.32)
Taxable fixed income (Barclays Capital US Aggregate Bond Index)	2.54	8.30
Tax-exempt fixed income (Barclays Capital Municipal Bond Index)	3.68	8.85
High yield bonds (Barclays Capital US Corporate High Yield 2% Issuer Capped Index)	11.60	42.53

Fund Summary as of April 30, 2010

Portfolio Management Commentary

How did the Fund perform?

• The Fund generated strong double-digit returns for the 12-month period,
but results trailed those of the broad-market S&P 500 Index and the
Russell 3000 Health Care Index, which returned 38.84% and 33.44%,
respectively. The following discussion of relative performance pertains
to the Russell 3000 Health Care Index.

What factors influenced performance?

• In spite of our unfavorable outlook for pharmaceuticals, stock selection
in that sub-sector was the Fund’s biggest source of relative strength
versus the benchmark. Specialty pharmaceuticals companies Warner
Chilcott Plc and Shire Pharmaceuticals Plc performed exceptionally
well over the last 12 months, thanks largely to more attractive valuations
and stronger growth projections relative to their larger, more diversified
counterparts. Other strong performers in the Fund on an absolute basis
included WebMD Health Corp., the industry’s leading on-line services
portal. On an absolute basis, all sub-sectors contributed positively to
final returns.

• Factors that detracted from performance included stock selection and
our overweight position in the biotechnology sub-sector, which lagged
the broader benchmark over the time period. One of our largest hold-
ings, Genzyme Corp., was hurt by manufacturing problems that caused
a temporary production plant shutdown. Additionally, higher than antici-
pated US health care reform costs hurt companies such as Gilead

Sciences, Inc., causing them to lower their forward-looking sales
guidance. Other areas of relative weakness included stock selection
within health care equipment and, to a lesser extent, in health care
services companies.

Describe recent portfolio activity.

• Portfolio activity during the period resulted in some changes to position-
ing. The most notable change was the elimination of several health care
equipment companies, which brought the Fund to an underweight posi-
tion in that sub-sector relative to the Russell 3000 Health Care Index.
Additionally, concerns over the potential costs associated with US health
care reform caused us to question the earnings sustainability of compa-
nies in that sub-sector. Proceeds from the sale of these companies were
reinvested across biotechnology, pharmaceuticals and managed care
stocks.

Describe Fund positioning at period end.

• At period end, we continue to favor the larger-cap biotechnology space,
where more established franchises have attractive valuations and strong
growth potential. The Fund also remains overweight in health care service
companies, particularly pharmacy benefit managers and drug distribu-
tors, that are positioned to benefit from higher volumes associated with
the expansion of medical coverage under the new US health care law.
The pharmaceuticals sub-sector continues to be the Fund’s largest
underweight, given its poor growth prospects.

The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions.
These views are not intended to be a forecast of future events and are no guarantee of future results.

About Fund Performance

• Institutional Shares are not subject to any sales charge. Institutional
Shares bear no ongoing distribution or service fees and are available
only to eligible investors.

• Investor A Shares incur a maximum initial sales charge (front-end load)
of 5.25% and a service fee of 0.25% per year (but no distribution fee).

• Investor B Shares are subject to a maximum contingent deferred sales
charge of 4.50% declining to 0% after six years. In addition, Investor B
Shares are subject to a distribution fee of 0.75% per year and a service
fee of 0.25% per year. These shares automatically convert to Investor A
Shares after approximately eight years. (There is no initial sales charge
for automatic share conversions.) All returns for periods greater than
eight years reflect this conversion. Investor B Shares of the Fund are only
available through exchanges, dividend reinvestments by existing share-
holders or for purchase by certain qualified employee benefit plans.

• Investor C Shares are subject to a 1% contingent deferred sales charge
if redeemed within one year of purchase. In addition, Investor C Shares
are subject to a distribution fee of 0.75% per year and a service fee of
0.25% per year.

• Class R Shares do not incur a maximum initial sales charge (front-end
load) or deferred sales charge. These shares are subject to a distribution
fee of 0.25% per year and a service fee of 0.25% per year. Class R
Shares are available only to certain retirement plans. Prior to January 3,
2003, Class R Share performance results are those of the Institutional
Shares (which have no distribution or service fees) restated to reflect
Class R Share fees.

Performance information reflects past performance and does not guar-
antee future results. Current performance may be lower or higher than
the performance data quoted. Refer to www.blackrock.com/funds
to obtain performance data current to the most recent month-end.
Performance results do not reflect the deduction of taxes that a share-
holder would pay on fund distributions or the redemption of fund shares.
Figures shown in the performance table on the previous page assume
reinvestment of all dividends and capital gain distributions, if any, at
net asset value on the ex-dividend date. Investment return and principal
value of shares will fluctuate so that shares, when redeemed, may be
worth more or less than their original cost. Dividends paid to each class
of shares will vary because of the different levels of service, distribution
and transfer agency fees applicable to each class, which are deducted
from the income available to be paid to shareholders.

Disclosure of Expenses

Shareholders of this Fund may incur the following charges: (a) expenses
related to transactions, including sales charges, redemption fees and
exchange fees; and (b) operating expenses including advisory fees, dis-
tribution fees including 12b-1 fees and other Fund expenses. The expense
example below (which is based on a hypothetical investment of $1,000
invested on November 1, 2010 and held through April 30, 2010) is
intended to assist shareholders both in calculating expenses based
on an investment in the Fund and in comparing these expenses with
similar costs of investing in other mutual funds.

The table below provides information about actual account values and
actual expenses. In order to estimate the expenses a shareholder paid
during the period covered by this report, shareholders can divide their
account value by $1,000 and then multiply the result by the number
corresponding to their share class under the heading entitled “Expenses
Paid During the Period.”

The table also provides information about hypothetical account values
and hypothetical expenses based on the Fund’s actual expense ratio
and an assumed rate of return of 5% per year before expenses. In
order to assist shareholders in comparing the ongoing expenses of
investing in this Fund and other funds, compare the 5% hypothetical
example with the 5% hypothetical examples that appear in other funds’
shareholder reports.

The expenses shown in the table are intended to highlight shareholders’
ongoing costs only and do not reflect any transactional expenses, such
as sales charges, redemption fees or exchange fees. Therefore, the hypo-
thetical example is useful in comparing ongoing expenses only, and will
not help shareholders determine the relative total expenses of owning
different funds. If these transactional expenses were included, shareholder
expenses would have been higher.

Class R	$1,000	$1,119.60	$10.98	$1,000	$1,014.44	$10.44

¹ For each class of the Fund, expenses are equal to the annualized expense ratio for the class (1.29% for Institutional, 1.54% for Investor A, 2.36% for Investor B, 2.36% for
Investor C and 2.09% for Class R), multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period shown).
² Hypothetical 5% annual return before expenses is calculated by pro rating the number of days in the most recent fiscal half year divided by 365.

Notes to Financial Statements

1. Organization and Significant Accounting Policies:

BlackRock Healthcare Fund, Inc. (the “Fund”) is registered under the
Investment Company Act of 1940, as amended (the “1940 Act”), as a
non-diversified, open-end management investment company. The Fund is
organized as a Maryland corporation. The Fund’s financial statements
are prepared in conformity with accounting principles generally accepted
in the United States of America (“US GAAP”), which may require the use
of management accruals and estimates. Actual results may differ from
these estimates. The Fund offers multiple classes of shares. Institutional
Shares are sold without a sales charge and only to certain eligible
investors. Investor A Shares are generally sold with a front-end sales
charge. Investor B and Investor C Shares may be subject to a contingent
deferred sales charge. Class R Shares are sold without a sales charge
and only to certain retirement and other similar plans. All classes of
shares have identical voting, dividend, liquidation and other rights and
the same terms and conditions, except that Investor A, Investor B,
Investor C and Class R Shares bear certain expenses related to the
shareholder servicing of such shares, and Investor B, Investor C and
Class R Shares also bear certain expenses related to the distribution of
such shares. Investor B Shares automatically convert to Investor A
Shares after approximately 8 years. Investor B Shares are only available
through exchanges, dividend reinvestments by existing shareholders or
for purchase by certain qualified employee benefit plans. Each class
has exclusive voting rights with respect to matters relating to its share-
holder servicing and distribution expenditures (except that Investor
B shareholders may vote on material changes to the Investor A
distribution plan).

The following is a summary of significant accounting policies followed by
the Fund:

Valuation: The Fund’s policy is to fair value its financial instruments at
market value using independent dealers or pricing services selected
under the supervision of the Board of Directors (the “Board”). Equity
investments traded on a recognized securities exchange or the NASDAQ
Global Market System are valued at the last reported sale price that day
or the NASDAQ official closing price, if applicable. For equity investments
traded on more than one exchange, the last reported sale price on the
exchange where the stock is primarily traded is used. Equity investments
traded on a recognized exchange for which there were no sales on that
day are valued at the last available bid (long positions) or ask (short
positions) price. If no bid or ask price is available, the prior day’s price
will be used, unless it is determined that such prior day’s price no longer
reflects the fair value of the security. Investments in open-end investment
companies are valued at net asset value each business day. Short-term
securities with remaining maturities of 60 days or less may be value at
amortized cost, which approximates fair value.

The Fund values its investment in BlackRock Liquidity Series, LLC Money
Market Series (the “Money Market Series”), at fair value, which is ordi-

narily based upon its pro rata ownership in the net assets of the under-
lying fund. The Money Market Series seeks current income consistent
with maintaining liquidity and preserving capital. Although the Money
Market Series is not registered under the 1940 Act, its investments will
follow the parameters of investments by a money market fund that is
subject to Rule 2a-7 promulgated by the Securities and Exchange
Commission (the “SEC”) under the 1940 Act. The Fund may withdraw
up to 25% of its investment daily, although the manager of the Money
Market Series, in its sole discretion, may permit an investor to withdraw
more than 25% on any one day.

In the event that application of these methods of valuation results in a
price for an investment which is deemed not to be representative of the
market value of such investment or is not available, the investment will
be valued by a method approved by the Board as reflecting fair value
(“Fair Value Assets”). When determining the price for Fair Value Assets,
the investment advisor and/or the sub-advisor seeks to determine the
price that the Fund might reasonably expect to receive from the current
sale of that asset in an arm’s-length transaction. Fair value determina-
tions shall be based upon all available factors that the investment advi-
sor and/or sub-advisor deems relevant. The pricing of all Fair Value
Assets is subsequently reported to the Board or a committee thereof.

Generally, trading in foreign instruments is substantially completed
each day at various times prior to the close of business on the New
York Stock Exchange (“NYSE”). Occasionally, events affecting the values
of such instruments may occur between the foreign market close and
the close of business on the NYSE that may not be reflected in the
computation of the Fund’s net assets. If events (for example, a company
announcement, market volatility or a natural disaster) occur during such
periods that are expected to materially affect the value of such instru-
ments, those instruments may be Fair Value Assets and be valued at
their fair values, as determined in good faith by the Board or by the
investment advisor using a pricing service and/or procedures approved
by the Board. Each business day, the Fund uses a pricing service
selected under the supervision of the Fund’s Board to assist with the
valuation of certain foreign exchange-traded equity securities and foreign
exchange-traded and OTC options (the “Systematic Fair Value Price”).
Using current market factors, the Systematic Fair Value Price is designed
to value such foreign securities and foreign options at fair value as of
the close of business on the NYSE, which follows the close of the
local markets.

Securities and other assets and liabilities denominated in foreign
currencies are translated into US dollars using exchange rates det-
ermined as of the close of business on the NYSE. Foreign currency
exchange contracts are valued at the mean between the bid and ask
prices and are determined as of the close of business on the NYSE.
Interpolated values are derived when the settlement date of the
contract is an interim date for which quotations are not available.

Notes to Financial Statements (continued)

Foreign Currency Transactions: The Fund’s books and records are main-
tained in US dollars. Foreign currency amounts are translated into US
dollars as follows: (i) market value of investment securities, assets and
liabilities at the current rate of exchange; and (ii) purchases and sales of
investment securities, income and expenses at the rates of exchange
prevailing on the respective dates of such transactions. Generally, when
the US dollar rises in value against foreign currency, the Fund’s invest-
ments denominated in that currency will lose value because its currency
is worth fewer US dollars; the opposite effect occurs if the US dollar falls
in relative value.

The Fund reports foreign currency related transactions as components of
realized gain (loss) for financial reporting purposes, whereas such com-
ponents are treated as ordinary income for federal income tax purposes.

Segregation and Collateralization: In cases in which the 1940 Act and
the interpretive positions of the SEC require that the Fund either delivers
collateral or segregates assets in connection with certain investments
(e.g., foreign currency exchange contracts), the Fund will, consistent with
SEC rules and/or certain interpretive letters issued by the SEC, segregate
collateral or designate on its books and records cash or other liquid
securities having a market value at least equal to the amount that would
otherwise be required to be physically segregated. Furthermore, based
on requirements and agreements with certain exchanges and third party
broker-dealers, each party has requirements to deliver/deposit securities
as collateral for certain investments.

Investment Transactions and Investment Income: For financial reporting
purposes, investment transactions are recorded on the dates the trans-
actions are entered into (the trade dates). Realized gains and losses on
investment transactions are determined on the identified cost basis.
Dividend income is recorded on the ex-dividend date. Dividends from
foreign securities where the ex-dividend date may have passed are sub-
sequently recorded when the Fund has determined the ex-dividend date.
Under the applicable foreign tax laws, a withholding tax at variable rates
may be imposed on capital gains, dividends and interest. Interest
income, including amortization of premium and accretion of discount on
debt securities, is recognized on the accrual basis. Income and realized
and unrealized gains and losses are allocated daily to each class based
on its relative net assets.

Dividends and Distributions: Dividends and distributions paid by the
Fund are recorded on ex-dividend dates. The amount and timing of divi-
dends and distributions are determined in accordance with federal
income tax regulations, which may differ from US GAAP.

Securities Lending: The Fund may lend securities to financial institutions
that provide cash as collateral, which will be maintained at all times in
an amount equal to at least 100% of the current market value of the
loaned securities. The market value of the loaned securities is deter-
mined at the close of business of the Fund and any additional required

collateral is delivered to the Fund on the next business day. Securities
lending income, as disclosed in the Statement of Operations, represents
the income earned from the investment of the cash collateral, net of
rebates paid to, or fees paid by, borrowers and less the fees paid to the
securities lending agent. Loans of securities are terminable at any time
and the borrower, after notice, is required to return borrowed securities
within the standard time period for settlement of securities transactions.
In the event that the borrower defaults on its obligation to return bor-
rowed securities because of insolvency or for any other reason, the Fund
could experience delays and costs in gaining access to the collateral.
The Fund also could suffer a loss if the value of an investment pur-
chased with cash collateral falls below the market value of loaned secu-
rities or if the value of an investment purchased with cash collateral falls
below the value of the original cash collateral received.

Income Taxes: It is the Fund’s policy to comply with the requirements
of the Internal Revenue Code of 1986, as amended, applicable to
regulated investment companies and to distribute substantially all of
its taxable income to its shareholders. Therefore, no federal income tax
provision is required.

The Fund files US federal and various state and local tax returns. No
income tax returns are currently under examination. The statute of lim-
itations on the Fund’s US federal tax returns remains open for each of
the four years ended April 30, 2010. The statutes of limitations on the
Fund’s state and local tax returns may remain open for an additional
year depending upon the jurisdiction. There are no uncertain tax posi-
tions that require recognition of a tax liability.

Recent Accounting Standard: In January 2010, Financial Accounting
Standards Board issued amended guidance to improve disclosures
about fair value measurements which will require additional disclosures
about transfers into and out of Levels 1 and 2 and separate disclosures
about purchases, sales, issuances and settlements in the reconciliation
for fair value measurements using significant unobservable inputs (Level
3). It also clarifies existing disclosure requirements relating to the levels
of disaggregation for fair value measurement and inputs and valuation
techniques used to measure fair value. The amended guidance is effec-
tive for financial statements for fiscal years beginning after December
15, 2009, and interim periods within those fiscal years, except for dis-
closures about purchases, sales, issuances and settlements in the roll-
forward of activity in Level 3 fair value measurements, which are effective
for fiscal years beginning after December 15, 2010, and for interim peri-
ods within those fiscal years. The impact of this guidance on the Fund’s
financial statements and disclosures is currently being assessed.

Other: Expenses directly related to the Fund or its classes are charged
to the Fund. Other operating expenses shared by several funds are pro
rated among those funds on the basis of relative net assets or other
appropriate methods. Other expenses of the Fund are allocated daily
to each class based on its relative net assets. The Fund has an

arrangement with the custodian whereby fees may be reduced by credits
earned on uninvested cash balances, which if applicable are shown
as fees paid indirectly in the Statement of Operations. The custodian
imposes fees on overdrawn cash balances, which can be offset by accu-
mulated credits earned or may result in additional custody charges.

2. Derivative Financial Instruments:

The Fund may engage in various portfolio investment strategies both to
increase the returns of the Fund and to economically hedge, or protect,
their exposure to certain risks such as foreign currency exchange rate
risk. Losses may arise if the value of the contract decreases due to an
unfavorable change in the price of the underlying instrument or if the
counterparty does not perform under the contract. To the extent amounts
due to the Fund from its counterparties are not fully collateralized con-
tractually or otherwise, the Fund bears the risk of loss from counterparty
non-performance. See Note 1 “Segregation and Collateralization” for
information with respect to collateral practices. In addition, the Fund
manages counterparty risk by entering into agreements only with coun-
terparties that it believes have the financial resources to honor their obli-
gations and by monitoring the financial stability of those counterparties.

Foreign Currency Exchange Contracts: The Fund may enter into foreign
currency exchange contracts as an economic hedge against either spe-
cific transactions or portfolio instruments (foreign currency exchange rate
risk). A foreign currency exchange contract is an agreement between two
parties to buy and sell a currency at a set exchange rate on a future
date. Foreign currency exchange contracts, when used by the Fund, help
to manage the overall exposure to the currency backing some of the
investments held by the Fund. The contract is marked-to-market daily
and the change in market value is recorded by the Fund as an unreal-
ized gain or loss. When the contract is closed, the Fund records a real-
ized gain or loss equal to the difference between the value at the time it
was opened and the value at the time it was closed. The use of foreign
currency exchange contracts involves the risk that counterparties may
not meet the terms of the agreement or unfavorable movements in the
value of a foreign currency relative to the US dollar.

3. Investment Advisory Agreement and Other Transactions
with Affiliates:

The PNC Financial Services Group, Inc. ("PNC"), Bank of America
Corporation ("BAC") and Barclays Bank PLC ("Barclays") are the largest
stockholders of BlackRock, Inc. ("BlackRock"). Due to the ownership
structure, PNC is an affiliate of the Fund for 1940 Act purposes, but BAC
and Barclays are not.

The Fund entered into an Investment Advisory Agreement with BlackRock
Advisors, LLC (the “Manager”), the Fund's investment advisor, an indirect,
wholly owned subsidiary of BlackRock, to provide investment advisory
and administration services. The Manager is responsible for the manage-
ment of the Fund’s portfolio and provides the necessary personnel, facil-
ities, equipment and certain other services necessary to the operations
of the Fund. For such services, the Fund pays the Manager a monthly fee
at an annual rate 1.00% of the Fund’s average daily net assets.

The Manager has voluntarily agreed to waive its advisory fees by the
amount of investment advisory fees the Fund pays to the Manager indi-
rectly through its investment in affiliated money market funds, however
the manager does not waive its advisory fees by the amount of invest-
ment advisory fees through its investment in other affiliated investment
companies, if any. This amount is shown as fees waived by advisor in the
Statement of Operations.

The Manager has entered into a separate sub-advisory agreement with
BlackRock Investment Management, LLC (“BIM”), an affiliate of the
Manager. The Manager pays BIM for services it provides, a monthly fee
that is a percentage of the investment advisory fee paid by the Fund to
the Manager.

For the year ended April 30, 2010, the Fund reimbursed the Manager
$6,244 for certain accounting services, which is included in accounting
services in the Statement of Operations.

The Fund has received an exemptive order from the SEC permitting,
among other things, to pay an affiliated securities lending agent a fee
based on a share of the income derived from the securities lending
activities and has retained BIM as the securities lending agent. BIM may,
on behalf of the Fund, invest cash collateral received by the Fund for
such loans, among other things, in a private investment company man-
aged by the Manager or in registered money market funds advised by
the Manager or its affiliates. The market value of securities on loan and
the value of the related collateral are shown on the Statement of Assets
and Liabilities as securities loaned and collateral at value-securities
loaned, respectively. The share of income earned by the Fund on such
investments is shown as securities lending — affiliated in the Statement
of Operations. For the year ended April 30, 2010, BIM received $19,505
in securities lending agent fees related to securities lending activities for
the Fund.

Notes to Financial Statements (continued)

The Fund has entered into a Distribution Agreement and Distribution
Plan with BlackRock Investments, LLC (”BRIL“), an affiliate of BlackRock.
Pursuant to the Distribution Plan and in accordance with Rule 12b-1
under the 1940 Act, the Fund pays BRIL ongoing service and distribution
fees. The fees are accrued daily and paid monthly at annual rates based
upon the average daily net assets of the shares of the Fund as follows:

	Service	Distribution
	Fee	Fee
Investor A	0.25%	—
Investor B	0.25%	0.75%
Investor C	0.25%	0.75%
Class R	0.25%	0.25%

Pursuant to sub-agreements with BRIL, broker-dealers and BRIL provide
shareholder servicing and distribution services to the Fund. The ongoing
service and/or distribution fee compensates BRIL and each broker-
dealer for providing shareholder servicing and/or distribution related
services to Investor A, Investor B, Investor C and Class R shareholders.

For the year ended April 30, 2010, affiliates earned underwriting dis-
counts, direct commissions and dealer concessions on sales of the
Fund’s Investor A Shares, which totaled $7,193.

For the year ended April 30, 2010, affiliates received the following con-
tingent deferred sales charges relating to transactions in Investor B and
Investor C Shares:

Investor B	$ 14,962
Investor C	$ 6,937

Furthermore, affiliates received contingent deferred sale charges of $49
relating to transactions subject to front-end sales charge waivers on
Investor A Shares.

PNC Global Investment Servicing (U.S.) Inc., an indirect, wholly owned
subsidiary of PNC and an affiliate of the Manager, serves as transfer
agent and dividend disbursing agent. Transfer agency fees borne by the
Fund are comprised of those fees charged for all shareholder communi-
cations including mailing of shareholder reports, dividend and distribu-
tion notices, and proxy materials for shareholder meetings, as well as
per account and per transaction fees related to servicing and mainte-
nance of shareholder accounts, including the issuing, redeeming and
transferring of shares, check writing, anti-money laundering services, and
customer identification services.

The Manager maintains a call center, which is responsible for providing
certain shareholder services to the Fund, such as responding to share-
holder inquiries and processing transactions based upon instructions
from shareholders with respect to the subscription and redemption of
Fund shares. For the year ended April 30, 2010, the Fund reimbursed
the Manager the following amounts for costs incurred in running the call

center, which are included in transfer agent — class specific in the
Statement of Operations.

Institutional	$2,948
Investor A	$3,251
Investor B	$ 600
Investor C.	$1,411
Class R	$ 233

Certain officers and/or directors of the Fund are officers and/or directors
of BlackRock or its affiliates. The Fund reimburses the Manager for com-
pensation paid to the Fund's Chief Compliance Officer.

4. Investments:

Purchases and sales of investments, excluding short-term securities
for the year ended April 30, 2010, were $306,166,056, and
$355,064,180, respectively.

5. Income Tax Information:

Reclassifications: Accounting principles generally accepted in the United
States of America require that certain components of net assets be
adjusted to reflect permanent differences between financial and tax
reporting. These reclassifications have no effect on net assets or net
asset values per share. The following permanent differences as of April
30, 2010 attributable to foreign currency transactions and net operating
losses were reclassified to the following accounts:

Paid-in capital	$ (2,859,152)
Accumulated net investment loss	$ 2,875,816
Accumulated net realized loss	$ (16,664)

As of April 30, 2010 the tax components of accumulated net earnings
were as follows:

Capital loss carryforwards	$(12,647,970)
Net unrealized gains*	64,416,841
Total	$ 51,768,871

* The differences between book-basis and tax-basis net unrealized gains were
attributable primarily to the tax deferral of losses on wash sales and the timing
and recognition of partnership income.

As of April 30, 2010, the Fund had capital loss carryforwards
available to offset future realized capital gains through the indicated
expiration date:

Expires April 30,
2017	$ 12,647,970

Notes to Financial Statements (continued)

6. Borrowings:

The Fund, along with certain other funds managed by the Manager and
its affiliates, is a party to a $500 million credit agreement with a group
of lenders, which was renewed until November 2010. The Fund may bor-
row under the credit agreement to fund shareholder redemptions. Prior
to its renewal, the credit agreement had the following terms: 0.02%
upfront fee on the aggregate commitment amount which was allocated
to the Fund based on its net assets as of October 31, 2008; a commit-
ment fee of 0.08% per annum based on the Fund's pro rata share of
the unused portion of the credit agreement, which is included in miscel-
laneous in the Statement of Operations, and interest at a rate equal
to the higher of the (a) federal funds effective rate and (b) reserve
adjusted one-month LIBOR, plus, in each case, the higher of (i) 1.50%
and (ii) 50% of the CDX Index (as defined in the credit agreement) on
amounts borrowed. Effective November 2009, the credit agreement was
renewed with the following terms: 0.02% upfront fee on the aggregate
commitment amount which was allocated to the Fund based on its net
assets as of October 31, 2009, a commitment fee of 0.10% per annum
based on the Fund's pro rata share of the unused portion of the credit
agreement and interest at a rate equal to the higher of (a) the one-
month LIBOR plus 1.25% per annum and (b) the Fed Funds rate plus
1.25% per annum on amounts borrowed. The Fund did not borrow under
the credit agreement during the year ended April 30, 2010.

7. Concentration, Market and Credit Risk:

The Fund invests a significant portion of its assets in securities in the
health care sector. Changes in economic conditions affecting the health
care sector would have a greater impact on the Fund, and could affect
the value, income and/or liquidity of positions in such securities.

In the normal course of business, the Fund invests in securities and
enters into transactions where risks exist due to fluctuations in the mar-
ket (market risk) or failure of the issuer of a security to meet all its obli-
gations (credit risk). The value of securities held by the Fund may decline
in response to certain events, including those directly involving the
issuers whose securities are owned by the Fund; conditions affecting the
general economy; overall market changes; local, regional or global politi-
cal, social or economic instability; and currency and interest rate and
price fluctuations. Similar to credit risk, the Fund may be exposed to
counterparty risk, or the risk that an entity with which the Fund has
unsettled or open transactions may default. The Fund manages counter-
party risk by entering into transactions only with counterparties that it
believes have the financial resources to honor their obligations and by
monitoring the financial stability of those counterparties. Financial
assets, which potentially expose the Fund to credit and counterparty
risks, consist principally of investments and cash due from counterpar-
ties. The extent of the Fund's exposure to credit and counterparty risks
with respect to these financial assets is generally approximated by their
value recorded in the Fund's Statement of Assets and Liabilities, less any
collateral received by the Fund.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors of BlackRock
Healthcare Fund, Inc.:

We have audited the accompanying statement of assets and liabilities,
including the schedule of investments, of BlackRock Healthcare Fund,
Inc. (the “Fund”) as of April 30, 2010, and the related statement of
operations for the year then ended, the statements of changes in net
assets for each of the two years in the period then ended, and the finan-
cial highlights for each of the five years in the period then ended. These
financial statements and financial highlights are the responsibility of the
Fund’s management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assur-
ance about whether the financial statements and financial highlights
are free of material misstatement. The Fund is not required to have, nor
were we engaged to perform, an audit of its internal control over finan-
cial reporting. Our audits included consideration of internal control over
financial reporting as a basis for designing audit procedures that are
appropriate in the circumstances, but not for the purpose of expressing
an opinion on the effectiveness of the Fund’s internal control over finan-

cial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts
and disclosures in the financial statements, assessing the accounting
principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. Our proce-
dures included confirmation of securities owned as of April 30, 2010,
by correspondence with the custodian and brokers; where replies were
not received from brokers, we performed other auditing procedures.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position
of BlackRock Healthcare Fund, Inc. as of April 30, 2010, the results
of its operations for the year then ended, the changes in its net assets
for each of the two years in the period then ended, and the financial
highlights for each of the five years in the period then ended, in con-
formity with accounting principles generally accepted in the United
States of America.

This report is not authorized for use as an offer of sale or a
solicitation of an offer to buy shares of the Fund unless accom-
panied or preceded by the Fund’s current prospectus. Past per-
formance results shown in this report should not be considered
a representation of future performance. Investment return and
principal value of shares will fluctuate so that shares, when
redeemed, may be worth more or less than their original cost.
Statements and other information herein are as dated and are
subject to change.

Item 2 – Code of Ethics – The registrant (or the “Fund”) has adopted a code of ethics, as of the end
of the period covered by this report, applicable to the registrant’s principal executive officer,
principal financial officer and principal accounting officer, or persons performing similar
functions. During the period covered by this report, there have been no amendments to or
waivers granted under the code of ethics. A copy of the code of ethics is available without
charge at www.blackrock.com.

Item 3 – Audit Committee Financial Expert – The registrant’s board of directors or trustees, as
applicable (the “board of directors”) has determined that (i) the registrant has the following
audit committee financial expert serving on its audit committee and (ii) each audit
committee financial expert is independent:
Kenneth L. Urish

Under applicable securities laws, a person determined to be an audit committee financial
expert will not be deemed an “expert” for any purpose, including without limitation for the
purposes of Section 11 of the Securities Act of 1933, as a result of being designated or
identified as an audit committee financial expert. The designation or identification as an
audit committee financial expert does not impose on such person any duties, obligations, or
liabilities greater than the duties, obligations, and liabilities imposed on such person as a
member of the audit committee and board of directors in the absence of such designation or
identification.

financial statements not included in Audit Fees.
2 The nature of the services include tax compliance, tax advice and tax planning.
3 The nature of the services include a review of compliance procedures and attestation thereto.

(e)(1) Audit Committee Pre-Approval Policies and Procedures:
The registrant’s audit committee (the “Committee”) has adopted policies and
procedures with regard to the pre-approval of services. Audit, audit-related and tax
compliance services provided to the registrant on an annual basis require specific pre-
approval by the Committee. The Committee also must approve other non-audit services
provided to the registrant and those non-audit services provided to the registrant’s affiliated
service providers that relate directly to the operations and the financial reporting of the
registrant. Certain of these non-audit services that the Committee believes are a) consistent
with the SEC’s auditor independence rules and b) routine and recurring services that will
not impair the independence of the independent accountants may be approved by the
Committee without consideration on a specific case-by-case basis (“general pre-approval”).
The term of any general pre-approval is 12 months from the date of the pre-approval, unless
the Committee provides for a different period. Tax or other non-audit services provided to
the registrant which have a direct impact on the operation or financial reporting of the
registrant will only be deemed pre-approved provided that any individual project does not
exceed $10,000 attributable to the registrant or $50,000 for all of the registrants the

Committee oversees. For this purpose, multiple projects will be aggregated to determine if
they exceed the previously mentioned cost levels.
Any proposed services exceeding the pre-approved cost levels will require specific
pre-approval by the Committee, as will any other services not subject to general pre-
approval (e.g., unanticipated but permissible services). The Committee is informed of each
service approved subject to general pre-approval at the next regularly scheduled in-person
board meeting. At this meeting, an analysis of such services is presented to the Committee
for ratification. The Committee may delegate to one or more of its members the authority to
approve the provision of and fees for any specific engagement of permitted non-audit
services, including services exceeding pre-approved cost levels.

(e)(2) None of the services described in each of Items 4(b) through (d) were approved by
the audit committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

(f) Not Applicable
(g) Affiliates’ Aggregate Non-Audit Fees:
	Current Fiscal Year	Previous Fiscal Year
Entity Name	End	End
BlackRock Healthcare Fund,	$17,651	$420,513
Inc.

(h) The registrant’s audit committee has considered and determined that the provision of
non-audit services that were rendered to the registrant’s investment adviser (not including
any non-affiliated sub-adviser whose role is primarily portfolio management and is
subcontracted with or overseen by the registrant’s investment adviser), and any entity
controlling, controlled by, or under common control with the investment adviser that
provides ongoing services to the registrant that were not pre-approved pursuant to paragraph
(c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal
accountant’s independence.

Regulation S-X Rule 2-01(c)(7)(ii) – $10,777, 0%

shareholders when a vacancy becomes available. Shareholders who wish to recommend a
nominee should send nominations which include biographical information and set forth the
qualifications of the proposed nominee to the registrant’s Secretary. There have been no
material changes to these procedures.

Item 11 – Controls and Procedures

11(a) – The registrant’s principal executive and principal financial officers or persons performing
similar functions have concluded that the registrant’s disclosure controls and procedures (as
defined in Rule 30a-3(c) under the Investment Company Act of 1940, as amended (the
“1940 Act”)) are effective as of a date within 90 days of the filing of this report based on the
evaluation of these controls and procedures required by Rule 30a-3(b) under the 1940 Act
and Rule 15(d)-15(b) under the Securities Exchange Act of 1934, as amended.

11(b) – There were no changes in the registrant’s internal control over financial reporting (as
defined in Rule 30a-3(d) under the 1940 Act) that occurred during the second fiscal quarter
of the period covered by this report that have materially affected, or are reasonably likely to
materially affect, the registrant’s internal control over financial reporting.
