A colonoscopy is an examination used to look for abnormalities or growths in the large intestine and rectum. Colorectal cancer is the second leading cause of cancer-related deaths in the United States, but with early detection, it’s treatable. In fact, about 90% of people live five or more years when their colorectal cancer is found early.
How It’s Done: A long, flexible tube with light and camera attachments—called a colonoscope—is inserted into the rectum and filled with air until the complete inner lining of the colon can be seen. Any polyps or abnormal areas seen during the procedure are removed and tested.
Doctors Who Perform Colonoscopy
