Prostate cancer screening may not reduce deaths

Men are being urged to consider risks before undergoing prostate cancer screening in the wake of two studies that did not produce convincing evidence that routine testing significantly reduces the chance of dying from the disease. The PSA blood test, which millions of men undergo each year, did not lower the death toll from the disease in the first decade of a U.S. government-funded study involving more than 76,000 men, researchers reported.
