It depends on what age you are. Anyone with symptoms such as diarrhea or bleeding should have one. Anyone over the age of 50 or with a family history of colon cancer should have one. Talk to your doctor for more details.

If you turned 50 and have no family history of colon cancer or colonic adenomas, your chances of colon polyps roughly doubles after that age. Following the adenoma-to-carcinoma theory, which postulated that most colon cancers start as benign adenomatous polyps, screening at 50 may detect and remove early adenomas, thus precluding cancer cells from ever appearing.
