What is a prostate specific antigen (PSA) test?
PSA is a protein produced by the prostate gland and is found in the blood of all men. The PSA blood test measures the amount of this protein in the blood stream. Some doctors believe men should have a PSA test to find cancer early and treat it before it spreads. Other doctors argue that the PSA test is not an effective screening test because there is no clear proof that having a PSA test improves your chances of being cured of prostate cancer.
