According to the American Cancer Society, beginning at age 50, both men and women should follow one of these testing schedules:
Tests that find polyps and cancer
- Flexible sigmoidoscopy every 5 years*, or
- Colonoscopy every 10 years, or
- Double-contrast barium enema every 5 years*, or
- CT colonography (virtual colonoscopy) every 5 years*
Tests that primarily find cancer
- Yearly fecal occult blood test (gFOBT)**, or
- Yearly fecal immunochemical test (FIT) every year**, or
The tests that are designed to find both early cancer and polyps are preferred if these tests are available to you and you are willing to have one of these more invasive tests. Talk to your doctor about which test is best for you.
The American Cancer Society recommends that some people be screened using a different schedule because of their personal history or family history. Talk with your doctor about your history and what colorectal cancer screening schedule is best for you. For more information on colorectal cancer screening, please call the American Cancer Society and ask for our document, Colorectal Cancer: Early Detection.
* If the test is positive, a colonoscopy should be done.
** The multiple stool take-home test should be used. One test done by the doctor in the office is not adequate for testing. A colonoscopy should be done if the test is positive.
