"Screening for prostate cancer did not seem to have a significant effect on mortality," wrote Gabriel Sandblom of the Karolinska Institute in Sweden and colleagues.
The study was paid for by the Swedish Cancer Foundation and other groups. It was published online Thursday in the journal, BMJ.
The American Cancer Society does not recommend routine screening for most men and there is no government screening program in Britain because officials say the PSA test is too unreliable. Two other big papers published in recent years have also failed to show much benefit for screening. That includes a large European study that found screening for prostate cancer could pick up cases a decade earlier, but to prevent one death from cancer, 1,410 men would have to be tested and 48 men treated.
False positive tests can cause significant harms, including psychological distress and treatments that can cause impotence and incontinence.
