writerblock-welcome to our conversation, as you can see, there are sometimes strong opinions voiced--and strong disagreement at times with what people choose to do. And, that can be a good thing.
I think, in your case, we as a group are truly posing this question: You're 85 years young--good for you for making it that far without major issues. Let's say your biopsy comes back positive (and it likely will--most american men your age have diagnosable prostate cancer)--what are you going to do then? Obviously, the first question is--how much is there? If you come back with a low-risk case, then entering into Active Surveillance would be obvious: chances are that if you're low risk at 85, you won't have to worry about
it unless you're planning on another 20 years or so.
Now, if you come back intermediate or high risk--then we can have THAT conversation. But I happen to think that is unlikely given your age and PSA.
Reality is that the general guidance is that for men of your age and condition is to not bother checking because chances are that even if PC is found, it's not going to advance to the serious level before something else gets you. The fact that you are regularly seeing a Urologist because of your need for finasteride got you the PSA.
Best of luck in deciding what to do--and it's good that you're asking questions--and the right questions to boot. My suggestion is, that while you're waiting on the biopsy--study up on the terms and their meaning, so that you're prepared to give a careful answer to the 'ok, what now?' that is coming next.
