I believe there are currently only 5 places in the USA offering Proton Treatment. The first and most experienced is at Loma Linda California. My father was treated for his Prostate Cancer there in 1997. He turns 77 in August. Other centers that offer Proton treatment are in Jacksonville, Florida. Central Indiana. I think one in Texas and 1 or two up in the North East Corridor.
I researched having the Proton treatments since my father did great with them but my insurance carrier denied coverage. I'm scheduled Aug. 12th for the DaVinci procedure.
