Colonoscopy
Colonoscopy is the inspection of the entire large intestine (colon) using a long, flexible, lighted viewing scope (colonoscope), which is usually linked to a video monitor similar to a TV screen. A colonoscopy may be done to screen for cancer or to investigate symptoms, such as bleeding.
Colonoscopy is done in the hospital or a doctor's office that has the necessary equipment. Preparation for the test includes emptying the bowels ahead of time using a laxative or enema. The person undergoing colonoscopy is given medication to relieve pain and to make him or her drowsy. A colonoscopy may take from 30 minutes to 2 hours.
A health professional will collect a tissue sample (biopsy) from any abnormal area. The tissue is then analyzed by a pathologist.
