Prostate Cancer PSA test how does it work | Free Article

Free Article - The PSA test measures the level of protein produced by the prostate gland. The doctor will take a blood sample and send it to a laboratory. This test is sometimes called a biological marker for cancer tumors. Men normally have low levels of PSA in their blood. If the rate is high, it could point to prostate cancer but it can mean there are other non-cancer conditions present in the prostate. As men get older, prostate cancer and other prostate problems become more of a problem. Enlarged prostate and prostatitis may raise the PSA levels in the blood. Neither of these problems causes cancer but it is possible for a man with one of these problems to develop prostate cancer. The PSA level will not tell the doctor if the patient has a benign prostate problem or cancer. The doctor will use the PSA test to decide if there should be a check for other signs of prostate cancer.
