Prostate-Specific Antigen (PSA)
The prostate specific antigen (PSA) test is a blood test that can help diagnose prostate problems including prostate cancer. It is not a perfect test. It will miss some prostate cancers, will detect some that would never go on to cause harm and can show a raised PSA level when there is no prostate cancer present.
