Doctors should no longer offer the PSA prostate cancer screening test to healthy men because they're more likely to be harmed by the blood draw — and the chain of medical interventions that often follows — than be helped, according to government advisory panel's final report.
Even after studying more than 250,000 men for more than a decade, researchers have never found the PSA to save lives, according to the U.S. Preventive Services Task Force, a panel of doctors that advises the government on cancer screenings and other ways to avoid disease.
