Colon Cancer Screening: Why It Matters and When to Start

Colorectal cancer is one of the most common cancers in the United States — and also one of the most preventable. The key is screening, which can catch problems early, often before any symptoms appear.

Why Screening Matters

Colon cancer usually begins as small growths called polyps. Many polyps are harmless, but some can develop into cancer over time. Screening allows your doctor to find and remove polyps before they ever become a problem — and to detect cancer at its earliest, most treatable stage.

When Should You Start?

Most major guidelines now recommend that people at average risk begin colorectal cancer screening at age 45. You may need to start earlier if you have a family history of colon cancer or polyps, inflammatory bowel disease, or certain genetic conditions. Talk with your doctor about the right timing for you.

What to Expect From a Colonoscopy

A colonoscopy is the most thorough screening option. After a preparation that cleanses the colon, you’re given medication to keep you comfortable while your doctor examines the colon and removes any polyps found. For people at average risk with normal results, it’s typically repeated about every 10 years. Other options, such as stool-based tests, are available and may be appropriate depending on your situation.
