In an article by Carter in BJUI (2013) the rationale and evidence for prostate cancer screening using PSA is reviewed. The author argues against a growing trend to abandon PSA to detect early prostate cancer, but suggests that not all age groups of men benefit. The age group of patients that benefit most from PSA testing is the 55-69 year old group. Below this age group (and certain,y below age 40) testing is not recommended unless there are high risk factors. Men in the target age group should be fully counselled about the risks of over diagnosis and after a normal test probably only need repeat testing every 2 years.
