ENDOSCOPIC SCREENING FOR COLORECTAL-CANCER

There is strong evidence that colon screening of asymptomatic, average -risk subjects can reduce colorectal cancer mortality. Endoscopic scre ening with sigmoidoscopy can reduce mortality associated with left-sid ed cancers due to the discovery of early curable cancers and the detec tion removal of premalignant adenomas. Screening with colonoscopy is w idely accepted for high-risk groups and would likely be effective for the screening of average-risk subjects.
