If you are age 50 to 75, get tested regularly for colorectal cancer. A special test (called a screening test) can help prevent colorectal cancer or find it early, when it may be easier to treat.

You may need to get tested before age 50 if colorectal cancer runs in your family. Talk with your doctor and ask about your risk for colorectal cancer.

How often should I get screened?
How often you need to get screened will depend on:

How do I decide which test to take?

There are different ways to test for colorectal cancer. Your doctor can help you decide which test you would prefer.

Before you talk with your doctor about which test to get, it can be helpful to think about your values and preferences. Answer these questions to find out which test you would prefer – then share the results with your doctor.

Together, you and your doctor can make a screening plan that’s right for you.

What are the different kinds of tests?

Several different kinds of tests can be used to screen for colorectal cancer. The main types are:

Stool tests are done at home. You collect a stool (poop) sample and send it to a lab for testing. Then the lab sends the results to your doctor.

Tests that look directly at your colon and rectum – like a colonoscopy – are done in a doctor's office or hospital. For these tests, you need to take a laxative to clean out your bowels before the appointment. You'll get anesthesia before the test, and you'll need someone to drive you home after the test.

Your doctor will tell you how to get ready for your test, including if you need to avoid certain foods beforehand. Learn more about colorectal cancer screening tests.

Does it hurt to get a colonoscopy?

Preparing for a colonoscopy can be unpleasant, but most people agree that the benefits to their health outweigh any discomfort. And getting anesthesia means you won’t have any pain or feel uncomfortable during the test.
