Colon Cancer Screening: What You Need to Know

Recommended Age for Screening

The American Cancer Society and the U.S. Preventive Services Task Force now recommend that people at average risk of colorectal cancer should begin regular screenings at age 45 because younger people are being diagnosed with colorectal cancers that are more advanced and deadly.

Types of Screening Tests

A colonoscopy is a procedure in which a thin, flexible tube with a camera is inserted into the colon to check for polyps, which can be removed before they become cancerous. Other screening options include stool-based tests and virtual colonoscopy (CT colonography).

Who Should Get Screened?

If you are age 45 or older and at average risk of colon cancer, meaning you have no colon cancer risk factors other than age, you should get screened. People with a family or personal history of colon cancer or certain inherited conditions may need to start screening earlier or get screened more often.

Benefits of colon cancer screening

Colorectal cancer is a preventable cancer, yet it is the second leading cause of cancer death in the United States. The key to improving early detection and prevention lies in increasing colorectal cancer screening rates among average-risk adults. Colorectal cancer screening has been proven to save lives, allowing for early detection and treatment of a potentially life-threatening disease. Early detection through screening can also lead to less invasive and more successful treatment options.

Talk to your doctor

If you are unsure about when to start screening or which test is right for you, talk to your doctor. They can help you assess your risk and choose the best screening option for you and provide the necessary follow-up care.
