Dr. Richard Ablin of the University of Arizona, who discovered the PSA test now says that routine PSA screening has become "a hugely expensive public health disaster." He says the screening procedure is too costly and ineffective. "I never dreamed that my discovery four decades ago would lead to such a profit-driven public health disaster," wrote Richard Ablin in a commentary for The New York Times. He adds, "So why is it still used? Because drug companies continue peddling the tests and advocacy groups push 'prostate cancer awareness' by encouraging men to get screened. PSA testing does have a place, after treatment for prostate cancer and for men with a family history of prostate cancer. Testing should absolutely not be deployed to screen the entire population of men over the age of 50, the outcome pushed by those who stand to profit."  See http://www.raysahelian.com/psa.html
