My doctor wants me to get a colonoscopy, but I don't know what it is. What is a colonoscopy and why is it important?

A colonoscopy is a procedure that uses a thin tube with a camera on the end to look inside your colon. It’s used to diagnose and treat certain conditions such as colorectal cancer, inflammatory bowel disease, and polyps. The test involves inserting the tube into your rectum and slowly moving it up through your colon. During the test, the doctor can view any abnormalities in the colon and take biopsies if necessary.
