Colorectal Cancer Screening
Colorectal Cancer Screening
Overview
What is colon cancer?
Colon cancer happens when cells that are not normal grow in your colon. These cells often form in polyps, which are small growths in the colon. Not all colon polyps turn into cancer. But most colon cancer starts in a polyp.
Your risk for colorectal cancer gets higher as you get older.
Who should be screened for it?
Your risk for colorectal cancer gets higher as you get older. Experts recommend starting screening at age 45 for people who are at average risk. Talk with your doctor about your risk and when to start and stop screening.
How often you need screening depends on the type of test you get:
- Stool tests. Every year for FIT or gFOBT.
- Tests that look inside the colon. Every 5 years for sigmoidoscopy. (If you do the FIT test every year, you can get this test every 10 years.)
Experts agree that people at higher risk may need to be tested sooner and more often. This includes people who have a strong family history of colon cancer. Talk to your doctor about which test is best for you and when to be tested.
