For years, Dr. Donald Layton made a point of urging other men to get screened for prostate cancer. A retired Mayo Clinic physician and prostate-cancer survivor, he was convinced the test was a lifesaver. But about a year ago, he had a change of heart. Today, he believes there's no reason for otherwise healthy men to go looking for trouble. "I stopped going out saying everybody should be tested," said Layton, 83. Layton has joined a growing chorus of skeptics who believe too much testing has led to an epidemic of over-diagnosis and over-treatment.
