Look into HIFU...High Intensity Focused Ultrasound...my hub had procedure (in Mexico by Florida doc)...tremendously successful..no drugs, no side effects, etc
I am 86 and have a large prostrate (120 grams) . The size of prostrate also has bearing on psa. I pay no attention to psa because of so many false. Reports.
I too was concerned for cancer but have had a microwave procedure about 10 years ago. I take 3 drugs that are supposed to shrink the problem. I have had 2 Urologists who said I need surgery it my 3rd says no and I do not have cancer. My prostrate is shrinking!!
