Colonoscopy Colon cancer can be completely prevented through colonoscopy.

• The current recommendations are for all patients to have screening colonoscopy at age 50 and every 10 years thereafter. Some physicians, however, recommend more frequent screening at 5-year intervals. Also, those at increased risk for colon cancer may be advised to undergo colonoscopy at an earlier age with more frequent follow-ups. Check with your primary care provider to find out what is best for you. Illustration courtesy of the National Cancer Institute, U.S. National Institute of Health/Terese Winslow, artist
