I also used that cream for radiation itchy and soreness. I am curious to why you chose proton beam other than the obvious as I had a consult at MGH as really wanted it for my ILC but the MGH team didn't think it would at all be a better approach than whole beam. At MGH they typically use proton beam for head, neck pediatric patients. I sure wish it was more widely used but very expensive and few in USA but good for you!
