*Update* I was part of a research study at the Mayo Clinic. While proton radiation is not typically used for breast cancer they are trying to make it standard care as it decreases exposure of the heart and lungs. I went through the whole treatment with just some minor pinkness to the skin. The following two weeks however, my skin became redder and redder, sore, and dried out. While this was very uncomfortable it was for a short amount of time and now I am pretty much completely healed and back to normal. I hope this might help someone else in the future.
