Annual screening for prostate cancer doesn’t cut men’s chances of dying from the disease, according to the latest results of a large screening trial. Comparing men who were screened each year with so-called PSA tests, for prostate specific antigen, or rectal exams to those who received their usual care, researchers found that more men in the screening group had been diagnosed with prostate cancer after 13 years -- but there was no difference in how many had died from it.
