I did get a quick response from Mayo, Phoenix. their team looked at my biopsy and scans and because proton radiation doesn't react well with cartlidge in the area, they said that I'm not a candidate for proton. So now I'm into more research of any alternatives to photon and it's side effects especially at my age. I may just continue on one day at a time and maintain what QAL I have for as long as I'm given.
