@mir123 -- When I had the radiation at a cancer center, I was told their state-of-the-art equipment was highly specific in hitting only the target area. It didn't go too wide or deep so it wouldn't affect my esophagus or lungs and it didn't. My radiation didn't even make my skin burn (just pink) until somewhere after 20 treatments. My question would be how old is that equipment? Is there equipment available somewhere else that can deliver more targeted therapy?
