GREEN, CDR, MC, USNR Since the mid-1980s, when the use of the prostate-specific antigen (PSA) screening test began to increase dramatically, the incidence of prostate cancer showed a concurrent steep rise. If early detection of prostate cancer truly saves lives, there should be a corresponding drop in the prostate cancer death rate. It hasnt happened. The prostate cancer death rate in the U.S. has not changed in 30 years. The vast majority of men with prostate cancer do not die of the disease because they have the slow-growing type that would never become lethal. Even if doctors could determine which cases of early-stage prostate cancer will be fatal (about 10-15%), there is no evidence that early detection will alter the outcome. About 2% who undergo prostatectomy die within 30 days of the operation.
