During a Colonoscopy your endoscopist passes a long flexible tube containing a camera and a light through your rectum and around the whole of your large bowel (colon). This allows your endoscopist to view the lining of this organ and enables the detection of subtle abnormalities.
A colonoscopy will help your doctor to find out why you are having symptoms and to make a diagnosis. It will give a clear view of the lining of the bowel and also allow your endoscopist to take tissue samples (biopsies) if necessary. It also allows for the removal of polyps (small wart like lesions that can become cancerous).
