Enormous Prostate Plan

Hi, all. I am new here. I had a PSA a few months ago and there was alarm when it came out to an 8 and change. They tested it again a few weeks later and it was an 11.3. A digital exam found nothing unusual but the doctor ordered an MRI, which did not show anything that looked obvious for cancer. "Highly Unlikely" was the finding. One horrible thing came out of it, though. A normal prostate apparently has a volume of 20-30, I believe? My doctor said he would be highly concerned if it was 60-80 or larger, but mine is 190 in volume. He was shocked that I have only mild symptoms related to it in terms of the "normal" enlarged prostate symptoms. (I urinate a little more often, infrequently start and stop, get up 1-2 times a night, etc. Normal sexual function.) My PSA was still at 11.8 after 3-4 weeks since the last 11. I don't know if it matters, but I am 6'7" and weigh just over 300 lbs., though I hold it well. (Most people guess I am 250-270 lbs.)

He has ordered a TRUS biopsy in a couple of weeks, despite the MRI findings being good. He says he does not wish to address the size of the prostate until he is 100% sure there is no cancer. I guess that is the wise choice? What do you think?

Afterwards, assuming the biopsy is clear, he wants to perform a TURP to remove excess prostate tissue. There are doctors here who can perform HeLoP, as well. Which is better? I have read that HeLoP is a better option than TRUS for large prostates like mine? (I'm hoping - even assuming - there are no signs of cancer, obviously, and that this is the path.) Thanks for any advice. I've been a bit anxious about it all, but am a man of faith, so not terribly stricken with worry. I appreciate any suggestions or thoughts!
