I've heard that I should get a colonoscopy. Why?

Colonoscopy is a test that uses a camera to look at the inside of your colon. It's used to diagnose and treat certain diseases, such as colon cancer. The procedure involves inserting a thin tube into the rectum and then slowly moving it up through the colon. During the procedure, doctors can take pictures of the inside of your colon and remove any polyps or other growths they find.
