Prostate Specific Antigen (PSA): PSA is a protein made by the prostate. Most PSA is found in semen, but some can be found in blood. A PSA test is a blood test that checks your PSA level.
High PSA levels provide a clue that a man may have prostate cancer. High levels may also be caused by cancer or non-cancerous conditions like infection, or an enlarged prostate. After treatment, your doctor will continue to monitor your PSA levels. If any prostate cancer cells remain after treatment they would cause a rise in the PSA.View Brochure
