The American Urological Association- an organization of board-certified urologists- is now condemning the routine use of PSA testing for prostate cancer, and for two reasons: 1) it's not that accurate, and 2) treating prostate cancer, even when it's confirmed, is often ill-advised. It is usually ill-advised.
Remember that the whole idea is to stay alive, and the data shows that men with prostate cancer who do nothing live as long as those who undergo radical treatment. So, what's the point? And the treatment is never harmless. It often results in impotence and/or incontinence and other harms.
It also results in pain, distress, risk of complications from the surgery, radiation, etc., and the surgery may even help spread cancer cells around. The tendency to get some cancer cells in the prostate gland is almost universal among men. In men who are in their 80s or older, the presence of such cells is almost guaranteed. But, they usually stay put in the gland and cause no trouble until the man dies of something else.
Basically, if you are an older man, and you are excreting your urine alright, and you're not in any pain, and there is no outward sign of trouble, then you shouldn't allow any prostate interventions. Forget about it.
Regarding the PSA test, it's just a blood test, so it's harmless in itself. So, if you really want to do it, you can. But, stick to the rule above regardless of the results.
I don't really recommend a passive approach. On the contrary, I think you should assume that prostate cancer is inevitable, and your goal is to minimize the risk of it, with the hope you never have to undergo drastic measures. A preventative program should include foods that have been shown to cut the risk, and they're all plants. I'm referring to foods like cruciferous vegetables, blueberries, and pomegranates. Eat tomatoes and tomato products to get the lypopene. Eat these high-antioxidant foods because they are likely to either prevent prostate cancer completely or keep it toned down and non-aggresive. And either of those outcomes are fine.
But, there is more that you can do. Taking high-dose VItamin D3 is a very good idea as a prostate cancer preventive. I recommend at least 5000 IUs daily.
Taking melatonin at night is a good idea for prostate cancer prevention. Melatonin is anti-mutagenic. I found this from the University of Maryland Medical Center: "
"Studies show that men with prostate cancer have lower melatonin levels than men without the disease. In test tube studies, melatonin blocks the growth of prostate cancer cells."
Other supplements can help too, such as resveratrol, which has the potential to inhibit prostate cancer cells. Good food and good supplements constitute a powerful double whammy against prostate cancer.
But, there is more yet that you can do. Keep your weight down. Getting heavy- especially in the abdomen with a pot belly- is very bad. It adds mechanical pressure which can impede drainage from the prostate, resulting in morbid accumulations.
And exercise- a lot- because when you exercise, you also relieve congestion in the prostate.
And have sex regularly- even as you get older- because it too relieves congestion in the prostate.
So, what I am saying is that, by all means, think of yourself as a prostate cancer patient and take all the lifestyle and nutritional measures that are proven to fight it. But, unless you have a urinary obstruction or are in pain or have a major clinical development, do not allow any conventional treatment. And if you skip the PSA test completely, it's fine with me.
