In this Tuesday, Oct. 11, 2011 photo, Terry Dyroff sits on the porch of his home in Silver Spring, Md. Dyroff's PSA blood test led to a prostate biopsy that didn't find cancer but gave him a life-threatening infection. Since Friday, Oct. 7, 2011, when a task force of independent scientists said PSA testing does more harm than good, urologists who make a living treating prostate cancer have rushed to defend the test, as have patients who believe it saved their lives. Less visible are the men who have been harmed by testing. The harm is not so much from the test itself but from everything it triggers - biopsies that usually are false alarms, and treatments for cancers that in most cases were not a threat.
