Medical panel advises against common prostate cancer test

      A national medical panel advises against men using the Prostate Specific Antigen test for cancer screening.

      The US Preventive Services Task Force is a panel of doctors who advise the government on cancer screenings and other ways to avoid disease.{} The panel says it found the PSA blood test unreliable, resulting in too many false positives.

      The PSA test measures a protein called prostate-specific antigen.

      The task force says the test often leads to unnecessary needle biopsies for men who don't actually have cancer.{}{}

      According to the American Cancer Society, prostate cancer is the second deadliest cancer among men, and occurs most often in African-American men.
