Which colorectal cancer screening test is explicitly named in USPSTF recommendations for adults aged 45 to 49 years?

• A. Colonoscopy
• B. Mammography
• C. PSA test
• D. DEXA scan

Answer: (A)

The main concept is recognizing a colorectal cancer screening test that USPSTF explicitly endorses for adults starting at age 45. USPSTF guidance lists several acceptable colorectal screening options, and among the choices given, colonoscopy is the test specifically identified as a colorectal cancer screening modality. It visualizes the entire colon and, if polyps are found, allows removal during the same procedure, providing both screening and immediate preventive therapy. When results are normal, colonoscopy is typically repeated about every 10 years. The other options target different organs or conditions (mammography for breast cancer, PSA for prostate cancer, DEXA for bone density) and are not colorectal cancer screening tests.
