On May 30, 2018 the American Cancer Society issued updated guidelines for colon cancer screening. One important change in the guidelines is that instead of starting colon cancer screening at age 50, the American Cancer Society now recommends that people start colon cancer screening at age 45. This change was made because studies have shown that the incidence of colon cancer is increasing in people younger than age 50. If you are age 45 or older, please discuss colon cancer screening with your doctor. In addition, if you are younger than age 45, you still may need to have colon cancer screening if you have a family history of colon cancer or if you have symptoms, such as rectal bleeding, etc.
