Another thread brought up the issue of routine PSA tests for prostate cancer. 17 years ago my GP ordered a routine PSA test during an annual physical exam. Results showed a higher than normal #. Biopsy showed cancer cells and I underwear radical prostatectomy. Urologist said I was his youngest prostate cancer patient. Two years later my 3 year year younger brother had the same experience, so he became our urologist's youngest. PSA has been undetectable since. So, there are times when a PSA test paid off. If you have any family history of prostate cancer, regular screening beginning early might be a life saver. I was 48 then. Just qualified for Medicare last month.
