Get a Colonoscopy
Colonoscopy lets a doctor closely see the inside of the entire colon and rectum. The doctor is looking for polyps which could be an early sign of cancer. Polyps are small growths that over time can become cancer.
The doctor uses a thin (about the thickness of a finger), flexible, hollow, lighted tube that has a tiny video camera on the end. This tube is called a colonoscope. The colonoscope is gently eased inside the colon and sends pictures to a TV screen. Small amounts of air are pumped into the colon to keep it open and let the doctor see clearly.
The exam itself takes about 30 minutes. You’ll probably be given medicine to help you relax and sleep while it’s done. You’ll need to plan on having someone go with you for this test so they can take you home afterwards.
Your health care provider decides how often you need this test, usually once every 10 years, unless you’re at a higher risk for colon cancer. It’s important that you talk with your provider to understand your risk for colon cancer, the guidelines you should follow for testing, and whether you need to start having the tests at age 45 or earlier.
