Summary
Colorectal cancer is a leading cause of cancer death in Israel. Our current understanding of the colorectal adenoma-carcinoma sequence has led to the use of screening for timely detection of polyps and cancer. Digital examination of the rectum is a test that can be performed by all doctors. Fecal occult blood testing, flexible sigmoidoscopy and colonoscopy are the standard screening techniques for patients. Computerized tomography colonography is now entering this field. This review discusses the merits and uncertainties of these strategies as related to the risk of colorectal cancer in selected populations.
