Hi - Everyone reacts differently to radiation; unfortunately, it sounds like you had a severe reaction. I'd surmise that next week's treatments, if they're not aimed at the burned area, won't worsen it. I think it takes a direct shot of radiation to produce burns. And be sure to wash off the aloe vera before getting radiation—IF they're radiating where the burn is. When I did radiation, I was told creams and jellies can affect its delivery. Bottom line: ask the tech(s) when you go in if you need to wash it off. Hope things go well this week so you can get past this and get healing- PJH
