What is colonoscopy done for?
A colonoscopy (koe-lun-OS-kuh-pee) is an exam used to detect changes or abnormalities in the large intestine (colon) and rectum.

What is the main cause of colon polyps?

Most polyps found during a colonoscopy can be removed safely and effectively during the procedure. In some cases, however, a colonoscopy can reveal that there are polyps too large to safely remove. These are complex polyps, which make up about 10-15% of all polyps, and usually require additional procedures to remove.
Why do I have to have a colonoscopy every 3 years?
