Which term is used for a screening test measuring a prostate-specific protein to assess prostate cancer risk?

• A. RP
• B. Phimosis
• C. PKD
• D. PSA

Answer: (D)

PSA, or prostate-specific antigen, is the screening test that measures a protein produced by the prostate in the blood. Higher PSA levels can indicate a greater likelihood of prostate cancer and prompt further evaluation, such as imaging or biopsy. However, PSA can also be elevated in non-cancerous conditions like prostatitis or benign prostatic hyperplasia, so it is not a definitive diagnostic test on its own. The other terms given refer to a surgical procedure (radical prostatectomy) or unrelated conditions (phimosis, polycystic kidney disease) and do not describe a test for a prostate-specific protein.
