While I had the good doctor with me, I did get to ask him a few additional questions that might help others here with their decisions. He is just one doctor, not a god, and doesn't claim to have all the answers, just sharing his opinions.
On seeding, he and his partners do a lot of them, he said it is only effective if the candidate is just squeaky clean perfect. He said you got to have a naturally normal or even smaller than normal prostate gland to start with, no more than a Gleason 6, low % of cancer in cores. With that said, he said they have had some good results. He said that if you have to be on HT for several weeks or months to shrink your prostate to the min. size, the treatment is not usually effective, his words, its like forcing a square into a round hole.
On HIFU, he thinks its a dangeorus method, and doesn't believe in all his experience that it will ever be approved by the FDA, despite current testing, etc. He doesn't believe that American healthcare providers would ever pay for it regardless. He felt the men that do it any way and go out of the country are entirely gambling their lives at their own risk. Just his opinion.
