About BREVAGen™

The BREVAGen™ breast cancer risk stratification test is a novel genetic test panel that examines a patient’s DNA to detect the absence or presence of certain common genetic variations (SNPs) associated with an increased risk for developing breast cancer.  The test is designed to help physicians assess aggregate breast cancer risk from these genetic markers, plus factors from a standard clinical assessment based on a patient’s family and personal history, thus giving a clearer picture of an individual woman’s risk of developing breast cancer.  The BREVAGen™ test may be especially useful for women predisposed to hormone dependant breast cancer, including those who have undergone breast biopsies, as the test will provide information that can help physicians recommend alternative courses of action, such as more vigilant, targeted surveillance or preventive therapy, on a personalized patient-by-patient basis.  For more information, please visit . http://www.brevagen.com.au
