Unfortunately the way the medical system works in the USA you can't just opt for part of a one treatment and then mix and match into a new and seemingly better treatment that seems right for you. Like HIFU and a bit of proton, they would not do it, even though they could. Just everything is done with clinical trials and so on, each is done separately. So to mix two like that they would have had to go through a trial with them together even if it is a good idea to do a mixing like that, and it seems like a good idea. It makes the US kind of both leading and archaic at the same time, true we test everything so we have less crazy stuff (snake oils), but one can't just do a logical mix that seems right and may help unless one has a doctor that goes outside guidelines which some doctors do do.
