To commemorate March as National Colon Cancer Prevention month, this edition of BenchMarks focuses on potential new screening methodologies for the early detection of colorectal cancers. An interview with Ernest Hawk, M.D., chief of Gastrointestinal and Other Cancers Research Group at the National Cancer Institute (NCI), covers colorectal cancer screening tools and compares and contrasts colonoscopy (or optical colonoscopy) with virtual colonoscopy.
