Here are some ... The controversy of routine PSA test has been around since its discovery (1970) but intensified drastically especially over the past 6 yrs. To get a glance at this dispute, please, at least, read the first 3 articles on http://formefirst.com/FreeInfoProstate.html. In my practice, I wouldn't test PSA annually for men >75; but I would do it if they're still in "good" health + abnormal rectal exam +.
No. Not recommended in general but in special cases it might be reasonable.
PSA. That is a very debated question. I personally believe, as a urologist who treats prostate cancer, that it is irresponsible to ignore men above a certain age just because of there age. Men still get high grade, aggressive prostate cancer that causes a painful death. Just because many men with prostate cancer have low grade disease, doesn't mean we ignore everyone else. Get an annual psa test.
