 Compelling Clinical Value: Strong Support From KOLs  16  “C-Scan® is a novel approach to improve colon cancer screening that can become an alternative to current screening methods. The device generates 3D colon mapping without the need for bowel preparation through which it  eliminates barriers for screening noncompliance and has potential to save people lives.” Professor Seth A. GrossAssociate Professor of Medicine at NYU School of Medicine; Gastroenterology Section Chief at Tisch Hospital; Director of Endoscopy at NYU Langone Medical Center  “C-Scan® is a swallow-and-forget breakthrough device that can change the history of colon cancer screening and prevention.” Professor Nadir Arber Professor of Internal Medicine and Gastroenterology Head, Health Promotion Center Head, Integrated Cancer Prevention Center, Tel-Aviv Sourasky Medical Center  “I believe that the diagnostic yield of the C-Scan® system, based on the combined diagnostic test, including scan imaging and gut motility, can be accepted as an important CRC screening tool following results’ validation on a larger data base.” Professor Jan Tack Professor of Medicine, Translational Research Center for Gastrointestinal Disorders (TARGID), University of Leuven, Belgium. Department of Clinical and Experimental Medicine, University of Leuven and Head of Clinic, University Hospital Gasthuisberg, Department of Gastroenterology  “The novel data on possible association between intestinal motility and colon polyps may provide new insight into the natural history of CRC. Identifying intestinal motility as a contributing risk factor for CRC has the potential to further improve screening protocols for patients at risk for CRC.” Professor Yehuda Ringel Chief, Division of Gastroenterology and Hepatology at Meir Medical Center, Affiliated with Tel Aviv University and Adjunct Professor of Medicine at the University of North Carolina at Chapel Hill
