What is a colonoscopy?

A colonoscopy is an examination of the lining of the colon with a lighted, flexible tube about the thickness of your finger. The doctor will insert the tube through your rectum and up through your colon, checking for abnormalities. Often during the colonoscopy, your doctor may perform other minor procedures such as a polyp removal. In addition, if necessary, a small piece of tissue (a biopsy) can be taken for examination in the lab. Please note that biopsies are taken for many reasons and do not necessarily imply cancer.
