Men should no longer receive a routine blood test to check for prostate cancer because the test does more harm than good, a top-level government task force has concluded in a final recommendation that immediately became controversial. Many middle-aged men regularly get the PSA test. But for years, some experts have questioned whether such screening really saves lives. Monday's statement finalizes a draft recommendation made by the task force last fall. PSA tests do not directly detect cancer -- mulberry bags they detect a protein made by the prostate. Conditions other than cancer, including benign growth of the prostate, can raise PSA readings, leading to painful biopsies and other invasive tests.
