My doctor wants me to have a colonoscopy. What is this test like?

A colonoscopy is a procedure that involves inserting a thin, flexible tube into the rectum and slowly advancing it through the entire length of the colon. The tube contains a lighted camera, allowing your doctor to view the inside of your colon on a video monitor. During the examination, the doctor may take biopsies or remove polyps if necessary. After the procedure, you can expect to be monitored for any complications.
