My primary care physician never ordered a PSA test (prostate specific antigen, that can be used to indicate prostate cancer.) for me during my supposedly “complete” physicals. He had read about a European study that showed that some men who had screening PSA tests were being misdiagnosed and were receiving unnecessary treatment too often while the screening only saved one man in 1000. His practice did not order PSA tests for white men below 60, with no family history of prostate cancer, with no urinary or sexual problems, and normal prostate exams results. In my 50s I changed insurance and as part of the switch was required to have a full physical by their doctors. They ordered a PSA test and my results came back shockingly high. ~18 g/dl . the retest aftera course of antibiotics came back 22! That is very bad. How long had it been growing in there? I never felt a thing. All my bits worked. I went to a urologist who examined my prostate. “The left side is hard” A 12 core biopsy confirmed ¾ were positive with up to 70% involvement. It would have cost virtually nothing to check the PSA box on the blood work sheet. Instead my doc focused on cholesterol and other things which were never a problem for me.
