At what age range does the USPSTF recommend colorectal cancer screening with colonoscopy for adults who are beginning routine screening?

• A. Screen with colonoscopy for adults aged 45 to 49 years
• B. Do not screen for colorectal cancer in this age group
• C. Screen with annual fecal tests only
• D. Screen with colonoscopy for adults aged 50 to 75 years

Answer: (A)

The main idea is when average‑risk adults should begin colorectal cancer screening and that colonoscopy is an approved way to start screening. The USPSTF now recommends starting routine screening at age 45 and continuing through age 75. Colonoscopy is one of the preferred screening options and is appropriate to begin at the start of routine screening; if the colonoscopy is normal, it is usually repeated every 10 years. So starting colonoscopy in the 45–49 age range fits the current guideline. The other options either reflect older start ages, suggest not screening, or imply a different single method, which doesn’t align with beginning routine screening at 45.
