PSA Blood Test

Testing the prostate-specific antigen (PSA) in the blood is usually done once per year for men over 40. The level of PSA in the blood can indicate a problem or potentially cancer in the prostate. There is some debate over the benefit of widespread testing of PSA levels however most men over 40 continue to have the test performed on an annual basis. They do this because prostate cancer can often be treated and early detection is important.
