In a study here in Sweden they did a test with 20000 men where half got PSA test every second year since 1998 and other half acted as control and did not. The group that got the PSA test had 30% less deaths by prostate cancer. That seems like a pretty decent way to judge success. https://gupea.ub.gu.se/handle/2077/57825 https://gupea.ub.gu.se/handle/2077/57825 page 92: Our data confirm that an organized screening programme reduces mortality by ~30%, a level that is similar to evidence from the ERSPC and the PLCO trial (showing a 25–32% lower risk) (175).
