What is a colonoscopy?
A colonoscopy is a procedure performed by your doctor to look at the inside of your colon (large intestine) and rectum.
A long, flexible tube is inserted into your rectum. There is a camera at the end of the tube that allows the doctor to see inside your colon.
A colonoscopy allows your doctor to see if there are signs of cancer or other diseases in your colon and rectum.
A colonoscopy is recommended for all adults starting at age 45-50 or earlier if you have a history of colon cancer in your family.
