Colon Cancer

Colonoscopy vs Sigmoidoscopy with FOBT



I`m 55 with no known family history of colon cancer. I recently had a Sigmoidoscopy. In conjunction with that, I did the fecal occult blood test. The results of the FOBT were negative and the Sigmoidoscopy was clear. Is this sufficient testing? The PA that did the test said the Sigmoidoscopy will catch any problems where problems normally occur and they only due a Colonoscopy on someone if a problem is found during the Sigmoidoscopy.


That is an acceptable combination. Asuuming that you don't have any other risk factors such as family history of colon cancer, you should get checked again in about 5 years.
