A practical guide on PSA testing

Prostate specific antigen (PSA) testing has been responsible for the earlier detection of prostate cancer, which has led to increased success of curative treatment. There is an increasing body of evidence that suggests the use of PSA testing leads to the detection of cancers at an earlier and more curable stage. Furthermore, there is increasing evidence that the falling death rate from prostate cancer can, at least in part, be attributed to the efforts of testing and early treatment. Also, in countries with a high uptake of PSA testing, there has been a consistently lower death rate from prostate cancer.
