Are colon cancer screenings necessary after a certain age?
Q. I am 77 and in overall good health. My previous colonoscopies to check for colon cancer have been normal. Can I stop having them?
A. The major benefit of colon cancer screening is seen in men ages 50 to 75. After age 75, the potential benefit is smaller, and the risks and side effects of the procedure — like bleeding and perforation of the colon — are higher.
