A colonoscopy is a procedure used to detect any abnormalities (precancerous growths or cancer) in the inner lining of the large intestine (rectum and colon). It involves the insertion of a thin, flexible tube with a camera attached. This lighted tube sends images of the large intestine to a monitor.

Before the procedure, patients are asked to follow a certain diet for several days (low-fiber, clear liquids). The evening before the colonoscopy, the patient will take a bowel-cleansing preparation.

If abnormalities are detected during the colonoscopy, the physician can remove them through the colonoscope. Tissue samples may also be removed at that time.

Patients are typically given medication to relax and sleep. Someone must be available to drive the patient home following the procedure.
