A friend told me about HIfu just weeks prior to treatment, it was the best decision I ever made, and the best money I ever spent....$25,000. plus travel expenses. Some insurance companies pay, but most dont, it isn't FDA approved so they can NOT pre-approve, if you call it surely will not be paid, but if you go ahead and then submit, you have a chance.
The chances of any side effects are extremely low, as it's High Intensity Focused Ultrasound, ultrasound is non-ionizing and doesn't hurt surrounding tissue. The most important thing is to find a very experienced doctor, as in anything, experience counts.
I had it done a year ago, no side effects, no problems, I have sent in many other men all report the same -- they are thrilled. My PSA is now 0.3, which is perfect as I still have a gland, just no cancer in it. Sex is great and I pee like a kid again, I cannot recommend HIFU enough. It will save your quality of life. All us HIFU guys are so happy we tend to get ourselves banned from forums as they accuse of of being salemen. Nothing can be further from the truth, we are simply very pleased and want to share the word.
I used Dr. S. Scionti of International Hifu, he is the doc that has trained alll the urologists around the country so they can work in the clinical trials or can be ready when it's FDA approved. HIFU has been in use in Europe for 18 years with a 94% success at 5 year rate, in Japan they post a 97% success rate at 5 years. If cancer reoccurs you can be reHIFUed, or surgery or radiation, no option is not an option. I know (through the web) a guy in the UK who was treated with HIFU 7 years ago, his PSA is 0.1, he has friends who also have been treated, similiar results, all no side-effects.
It is in clinical trials in the USA, there are too many restrictions on the trials, but I have a list of all of them and their phone numbers if you want.
Comparing ultrasound and radiation, I think they both are the same technology--they target the gland, only ultrasound cooks the tissue whereas radiation alters the DNA. With HIFU, no cutting is involved, so no risk from surgery.
Good luck in whatever you chose!
I am happy to answer any questions.
