Welcome

Colon cancer — which includes cancers of both the colon and the rectum — is the second-leading cause of cancer death in the United States. Just as not smoking goes a long way in preventing lung cancer, regular testing for and removal of colon polyps — small, protruding clumps of cells on the inside wall of the colon — can prevent colon cancer. Whether or not you've decided to get screened, you may feel overwhelmed by all the testing options available.

Factors to consider

This guide is designed to help you make an informed decision about your colon cancer screening options. As with most things, one size doesn't fit all. Think of yourself and your doctor as partners in the decision-making process. Your decision about what screening test or tests are best for you will most likely be based on a number of factors, including your:

• Age
• Medical history
• Comfort level

As you use this guide, you'll learn how colon cancer develops and whether you're at increased risk of this disease. You'll also get a detailed look at what's involved with each of the most commonly used screening tests, and you'll see and hear directly from a Mayo Clinic doctor who specializes in diagnosing and treating colon cancer. Whichever screening test — or tests — you choose, remember that if you're at average or higher than average risk of colon cancer, some screening is better than no screening. Proper screening aids in early detection, which helps ensure timely treatment for this potentially fatal disease.

Take about 30 minutes or more to go through this information in sequence by following the links at the end of each page. Doing so will help you understand more about colon cancer, your screening options, and the pros and cons to consider as you make your decision.
