Can you advise on prostate cancer?

So my biopsy and MRI showed cancer cells according to the doctor. He's not my favorite. He's older and speaks like a surgeon. But mumbles. So I gather that the right side(?) of my prostate has ten years c cells and he states three choices. Monitor it. Radiate it. A procedure I couldn't catch the name of but involves burning the cells via rectal entrance in and out but resume normal activity but with a catheter for a few days. He thinks I should do it now.

As my PCP set me up with routine exams by four specialists plus two I was already seeing, I've been on a visit-test-visit merry-go-round all year and this was the last reminder on my list. I'm not anxious to do anything other than my regular dental visit for a while.

I'm 81 and type II, but aside from minor kidney and liver problems, nothing to prevent me from living probably longer than I need to.

What are you able to say about the procedure or radiation, even monitoring?

And any guess as to what type of c is involved?

I'm going to have his info sent to my PCP for his thoughts, but you all are a good and different source than a doctor. Thanks.
