Mat:
I had proton therapy at Loma Linda 5 yr ago - completely noninvasive and have had not side effects.
As for it taking 9 weeks - the intervention you choose could have a substantial impact on your quality of life, so you must be ready to accept the side effects in case you are one of the unlucky ones. I figured 9 weeks was a good trade off for no side effects. Also, my younger brother has surgery 8 yr ago by a top doctor in NC and was told he had clean margins. Two years ago his PSA began to rise, so there is no guarantee.
Protonbob.com will get you alot of testimonials and numbers you can call to talk to guys who have gone thru it. It is covered by Medicare.
