PSA testing is a blunt tool, and often gives misleading results. A contrast scan, which I had, is more reliable. Most men of a certain age, me included have an enlarged prostate, so a regular scan is sensible. Mine is repeated every 18 months. As my pathologist friend remarked, far more men die with prostate cancer, than die of it. However. That doesn't mean that it should be ignored. I think a lot of men are concerned about the possible effects of treatment, lack of erection, incontinence, etc, so put off checking.
