Find and Remove Precancerous Polyps
During a colonoscopy, your doctor inserts a thin, flexible tube with a high-definition camera on the end into the rectum. This allows them to view the inside of the colon, also known as the large intestine, to look for and remove growths called polyps. Polyps 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.
Colonoscopies are used for the detection of early colorectal cancers. If caught early, colorectal cancer can be cured.
