CHICAGO, April 28 (UPI) -- Prostate specific antigen screenings using genetic variants may become more accurate and cut down on unnecessary prostate biopsies, U.S. researchers say.
Lead author Dr. Brian Helfand -- an adjunct assistant professor of cell and molecular biology at Northwestern University Feinberg School of Medicine -- said personalized PSA testing using genetic variants could account for an 18 percent reduction in the number of men who likely would have undergone unnecessary biopsies.
