My doctor says that I need to get a colonoscopy. What does that mean and how often do I need to do it?

A colonoscopy is a procedure where a doctor uses an endoscope (a long, flexible tube with a camera on the end) to examine the inside of your colon. It’s done in a hospital or clinic setting, and involves drinking a laxative to help clean out your bowels before the test. The doctor will then insert the endoscope into your rectum and slowly move it up through your colon. During the exam, the doctor can look at the walls of your colon, remove any polyps, and take biopsies if necessary. After the exam, you'll be given a cleansing enema to help clear out any remaining material.
