A colonoscopy involves the insertion of a flexible tube (colonoscope) through the anus and rectum to examine the entire colon. A tiny camera at the end of the scope allows the physician who is administering the procedure to see inside your colon. If any abnormal tissue growths, including polyps, are found during the procedure, they will be promptly biopsied or removed and sent to the pathology laboratory for a microscopic look.
A colonoscopy is an excellent – in fact, the best – screening procedure that allows for the detection and, subsequently, prevention of colorectal cancer. When it comes to colon cancer and precancerous lesions, early detection is important for ultimate cure.
