Al, your doctor is likely making a good call --- for him. For you, perhaps not. Chances are remote that you've got a problem, but at your age you should have more real data to assure you of this than your doctor's opinion, as excellent and as well founded as it may be.
I encourage you to have a PSA and a DRE. As you can see below, I had a low PSA, and no lump evidence on a DRE, although one side was said to be enlarged. Because of a family PCa history my doctor sent me to a urologist who, when he looked at my PSA said, "What are you doing here!" But, he too was of the cautious sort and because of family history did a biopsy. He was surprised it showed cancer. I wasn't thrilled, but a heck of a lot happier to know it was there and treat it, than to not know it was there and not treat it.
I tell you the above as an example that cautious is good. Go do the cautious thing and then I hope you'll report back.
