According to the US Preventive Services Task Force, PSA tests are useless and men should not have them. The conclusion is based on five clinical trials that showed that PSA testing does not save lives and that having the test leads to more tests and treatments that cause impotence, incontinence and other unpleasant side effects. The false positive rate for PSA testing is 78%. Prostate cancer is a disease of aging; some men die of prostate cancer, all men die with it. The measurement is meaningless; a man with a PSA of 0.5 can have cancer, while a man with a PSA of 11 could be cancer-free. Furthermore, so many things affect the PSA results like, travel, exercise, sex, BPH, prostatitis, caffeine, etc… PSA is prostate specific antigen, it is not cancer specific. The results of PSA testing are slightly better than flipping a coin. 

In conclusion, there are an estimated 1 million men in the US who have had a prostatectomy (removal of prostate) who are now impotent, and/or incontinent, wearing diapers, and unable to achieve an erection after having surgery for a disease they didn’t even have!

** I am not telling men whether or not to have a PSA test. I'm simply providing the data that's out there so more well informed decisions can be made by the public.
