The data from the Göteborg study may still not provide a convincing rationale for mass, population-based screening based on use of the PSA test, but it certainly does set the standard for what must be expected from any new test that may come along and show promise as a true screening test for prostate cancer in the future.
Reuters and other news agencies gave widespread coverage to the Swedish study over recent days.

Over 14 years of follow-up, prostate cancer death rates were cut almost by half in the (PSA) screening group compared with the non-screening group, as men were diagnosed and treated in time to stop the cancer from killing them.
Jonas Hugosson, who led the study, said the results showed that PSA screening of all men this age group “can result in a relevant reduction in cancer mortality.”
But the findings don’t necessarily mean nationwide prostate screening programs should introduced, experts said, since they run the risk of significant overdiagnosis of tumors in men who would not have suffered any harm from their cancer.
