Why Get a Colonoscopy?
Find and Remove Precancerous Polyps
During a colonoscopy, the doctor inserts a thin, flexible tube with a high-definition camera at its tip into the rectum. This allows the doctor to view the inside of the colon, also known as the large intestine, to look for and remove growths called polyps. Polyps (called adenomas) may be precancerous, which can lead to colon cancer.
Additional Reasons for a Colonoscopy
We also use colonoscopy to detect and examine inflamed tissue, ulcers, and bleeding, and to diagnose causes of unexplained changes in bowel habits.
