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 test that uses a camera to examine the inside of your colon (large intestine). It is used to diagnose and treat various health conditions such as polyps, cancer, inflammatory bowel disease, and other diseases. The colonoscopy can also be used to screen for colorectal cancer.
