Colorectal Cancer - Exams and Tests

Early detection

Routine screening can reduce deaths from colorectal cancer. Some screening tests find and remove polyps before they can turn into cancer. Other screening tests look for early signs of cancer. Colorectal cancer has a much better chance of being successfully treated when it is found early.

Stool tests look for signs of cancer. If used as recommended, these tests may find cancer early, when treatment works better. Sigmoidoscopy and colonoscopy are tests that find and remove polyps to stop them from turning into cancer. Virtual colonoscopy finds polyps. With stool tests and virtual colonoscopy, if there are abnormal findings, you will need to have a colonoscopy to remove any polyps.

Talk to your doctor about which test is right for you. People with a higher risk for colorectal cancer, such as those with a strong family history of colon cancer, may need to start routine testing before age 50 and have it more often.
