My doctor has recommended that I get a colonoscopy. What is a colonoscopy and why is it important?

A colonoscopy is an examination of the large intestine (colon) using a thin, flexible tube called an endoscope. It can be used to diagnose certain medical conditions, such as polyps or cancer, in the colon. Colonoscopy can also help detect inflammatory bowel disease, which is a condition where the lining of the intestines becomes inflamed.
