PSA test is pretty much a constant beyond a certain age. My doctor in the last decade told me I still have the prostate of a young man. For the good it does me I suppose.

What that examination did for me. It indicated that some change of the prostate was probably normal over the years. I do not know the best age to start.

Yet everything indicates a yearly extensive blood testing and urine testing. Will head off conditions that more often than suspected will present for some form of treatment.

Few of us last the distance without some issue or issues. I believe for example that beyond a certain age. If your doctor does not have you on 81mg of asprin daily. You might ask him. No gaurantees they will prevent heart attacks. Yet there exists tons of evidence they reduce the chance substantially. It was the worlds first wonder drug. It also does not seem to reduce the potency effect with usage.
