Prostate cancers detected by screening have a higher rate of organ-confined disease and a lower rate of extracapsular extension and positive surgical margins than non-screen-detected cancers, say researchers.
The widespread use of prostate cancer screening had led to stage migration, with more cancers detected at a lower stage, which has led to a reduction in the age-adjusted mortality rate. However, it is not clear whether some men are being treated unnecessarily, says the team.
Another study that shows men that are screened for prostate cancer with PSA bloodwork have cancers that are more likely to be contained to the prostate.
