Ulrike, I think your response to radiation is not unusual. People do vary in how much they burn. I had a fairly extensive area of burns that looked really bad to me, but my doctor was saying how pleased she was with how well my skin was holding up. Sometimes radiation has to be stopped because the skin breaks down. I was getting extra radiation because 16 of my lymph nodes were positive, and seeing that you are Stage 4, I'm guessing that your doctor might be giving you more radiation than some of your friends whose cancer is less advanced have received. Studies show that radiation really works, so try to hang in there. The nurse should be able to give you some creams and dressings that will help.
