What is the starting age for colorectal cancer screening according to USPSTF guidance?

• A. 40 years
• B. 45 years
• C. 50 years
• D. 60 years

Answer: (B)

Starting age for colorectal cancer screening in average-risk adults per USPSTF is 45 years. This update reflects evidence that colorectal cancer is increasingly diagnosed in people in their 40s and that beginning screening earlier improves the chance of detecting precancerous polyps and cancers at a treatable stage. If you’re at average risk, you should start screening at 45 and continue through age 75, with the screening method and interval chosen based on patient preference and risk factors. Common options include colonoscopy every 10 years, or alternative tests such as sigmoidoscopy every 5 years, CT colonography every 5 years, or stool-based tests annually. Those with higher risk—such as a strong family history, certain hereditary conditions, or inflammatory bowel disease—might start earlier and/or have different intervals per clinical guidance.
