An American Cancer Society study says far fewer U.S. men are being diagnosed with early prostate cancer and getting blood tests to detect the disease. That's since an influential government-appointed panel recommended against routine screening more than three years ago.
A big question remains: Did that shift have any effect on death rates from prostate cancer?
Doctor groups used to recommend routine, yearly PSA screening starting at age 50. Elevated levels sometimes indicate prostate cancer, but they also can be caused by other things.
