Colonoscopy is a procedure used to observe and detect changes or irregularities inside the rectum and colon (large intestine).
The General Surgeon or Gastroenterologist uses a colonoscope (thin tube) containing a small attached camera, inserts it into the rectum, and moves it into the large intestine (colon), taking pictures and viewing all of this on a screen.
Tissue samples (biopsies) may be taken during a Colonoscopy.
