(AP) - A big study of men in Europe gives mixed results about the value of prostate cancer screening.
The study finds that PSA blood tests every four years seem to cut the risk of death from prostate cancer. But it also finds that screening makes no difference in overall mortality rates because most men die of other causes -- not their prostate tumors.
A government-appointed task force in the United States has advised against routine screening, saying it is doing more harm than good by leading to treatment of many tumors that grow so slowly they would never threaten a man's life.
The new study involves more than 160,000 men in eight countries. Results are in Thursday's New England Journal of Medicine.
