Hi there. I have been down this road myself personally. Get your biopsies done. First things first. If they are positive for cancer then the next question will be has that cancer escaped outside the prostate capsule? Chances are that it will not have because your PSA raise is relatively recent. Either way be guided by your urologist and oncologist if you have one. You have everything going for you and your age is an advantage. My feeling is that you will be fine. If I can help more let me know.
