Doctors can diagnose colon cancer in a few different ways. This may include blood and stool tests, CAT scans, PET scans, and the most common being a colonoscopy.
What is a Colonoscopy?
A colonoscopy allows doctors to detect changes or see abnormalities in the colon and rectum. During the procedure a long flexible tube is inserted into the rectum. A small video camera on the end of the tube allows doctors to view the interior of the colon to detect any abnormalities.
How to Prepare for a Colonoscopy?
Your doctor will prescribe you a pre procedure prep kit to help clear out your colon before the procedure. Your doctor will also give you detailed instructions on what to eat the day before and the morning of your procedure.
