Question

Colon cancer screening: At what age can you stop?

I'm 76 years old and am wondering when it's no longer necessary to get colon cancer screening? Is there an upper age limit?

Answer

from Michael Picco, M.D.

People over age 75 who have been getting regular colon cancer screening since age 50, and who have had consistently negative screenings — no polyps (adenomas) or colon cancer — need not continue getting routine screening. That's according to colon cancer screening guidelines issued by the U.S. Preventive Services Task Force (USPSTF). The upper age limit was set after studies determined that the net benefit of screening after age 75 was small. However, the USPSTF guidelines do recommend colon cancer screening for people over age 75 who have an increased risk of colon cancer, such as family history or a previously diagnosed colon cancer.

The USPSTF recommends that colon cancer screening be done using high-sensitivity fecal occult blood testing (FOBT), sigmoidoscopy with FOBT, or colonoscopy.

Talk with your doctor about what colon cancer screening option is best for you. Together, you can decide based on your overall health when screening may no longer be of benefit.
