Researchers at the Johns Hopkins Brady Urological Institute, Wake Forest University and the Karolinska Institute in Sweden have identified an array of gene markers for hereditary prostate cancer that, along with family history for the disease, appear to raise risk to more than nine times that of men without such markers. The panel, gleaned from a study of more than 4,000 Swedes, found that these markers are common and could account for nearly half of the prostate cancer cases in this study. Results are published online in the Jan. 16 edition of the New England Journal of Medicine.
