Hello and welcome to Healing Well, dsdmike. Sorry you need to be here, but glad you found us on the web. We have a great group of men and women here, all will be eager to help you, give you hope and encouragement, and all the advice you can stand, lol.
Why do you not want a needle biopsy? Are you fearful of anticipated pain or perhaps the fact that its a somewhat humiliating procedure? Most of us didn't experience too much discomfort having biopsie performed, I had 3 of them along the way, 2 didnt hurt, 1 did mildly, some men here have been put under to have it done.
With your stated numbers, it would be normal at this point to have the biopsy done, my last one was a targeted one, and it wasn't bad at all.
At age 70, and no disrespect to your age, watchful waiting might make sense, once you know the extent of any possible PC. You would also want to factor in your other health issues, if you have them.
I am sure others here will give you their take on the biopsies, as a rule, its really not that bad, its one of those things, that thinking about it is worse then doing it.
Good luck to you, and again ,glad you found us here.
