There is a guy who posts on LinkedIn about the proton center in Prague and rates it very highly. Personally, I was fortunate to have my insurance cover all of my proton therapy at UPenn Hospital in Philadelphia. 9 weeks, one treatment per day, 5 days per week. Completely painless and non-invasive (other than the balloon - another story!). PSA down from 6.45 to <1 in a year. No side effects. Not even on tamsulosin any more.
Ia m more than willing to share my story about why I believe proton is the best way to go.
