My doctor has suggested that I get a colonoscopy. What's a colonoscopy and why do I need one?

A colonoscopy is a test that uses a thin, flexible tube called a colonoscope to examine the inside of your colon. The test is done by a healthcare provider who inserts the scope into your rectum and slowly moves it through your digestive system. This allows the provider to view the lining of your colon and any polyps or other abnormalities.
