In 1985, a US man had an 8.7% lifetime risk of receiving a diagnosis of prostate cancer and a 2.5% risk in his life of death from the disease; these two risks today are 17% and 3%, respectively (1,2). Prostate-specific antigen (PSA) screening is largely responsible for this increase in diagnosis; its contribution to the 31% fall in mortality between 1990 and 2003 remains a subject of heated debate (2). Along with the substantial increase in detection of the disease has been a concomitant stage migration from tumors of high volume and grade to tumors of lower volume and gradeand presumably of lower biologic potential.
