At what ages and with what tests is routine prostate cancer screening typically considered, and what is one limitation of PSA screening?

• A. Begin discussing screening at age 60 for average risk; tests: PSA and DRE; limitation: PSA elevated only with cancer
• B. Begin around age 50 for average risk; tests: PSA and DRE; limitation: elevated PSA can occur with prostatitis and BPH
• C. Begin at age 40; tests: PSA only; limitation: None
• D. Begin at 55; tests: DRE only; limitation: None

Answer: (B)

Prostate cancer screening decisions hinge on when to start, what tests to use, and understanding what the tests can and cannot tell us. For average-risk men, starting routine screening around age 50 is typical, using both the PSA blood test and the digital rectal exam. The PSA test is not cancer-specific—levels can rise for reasons other than cancer, such as prostatitis (infection/inflammation) or benign prostatic hyperplasia (BPH). This limitation means a higher PSA doesn’t prove cancer and can lead to unnecessary procedures if not interpreted in context. That combination of age, using both PSA and DRE, and recognizing that PSA elevation may reflect non-cancer conditions makes the option with these elements the best fit.
