What is the USPSTF recommendation for colorectal cancer screening in adults aged 50 to 75 years?

• A. Screen with colonoscopy for all adults 50 to 75
• B. Screen with colonoscopy only if symptomatic
• C. Do not screen
• D. Screen with colonoscopy for 60 to 75 only

Answer: (A)

Screening for colorectal cancer is recommended for adults aged 50 to 75, because finding cancer early or removing polyps before they turn into cancer saves lives. Colonoscopy is a proven option within USPSTF guidelines because it directly visualizes the entire colon and, if polyps are found, allows their removal in the same procedure, reducing both cancer incidence and mortality. When someone is at average risk, a normal colonoscopy is typically repeated about every 10 years, making it a convenient long-term strategy for prevention and early detection. The USPSTF also accepts other valid screening methods, so the key point is that screening should occur in this age range and that colonoscopy is one strong, widely used option among several, rather than waiting for symptoms or limiting screening to a narrower age span.
