I've heard that a colonoscopy is a good way to find problems with the colon. Is this true?

Yes, a colonoscopy can be used to diagnose and treat certain diseases of the colon. It involves inserting a thin flexible tube into the rectum and then slowly moving it up through the colon until it reaches the cecum. This allows doctors to view the entire length of the colon and identify any abnormalities or polyps.
