Welcome, Nannygranny6. Boy oh boy, but you have had a rough ride! Okay, first you need to tell us what kind of radiation you are having, standard or IMRT, and whether or not you will be having chemo at the same time, and if so, what chemo drugs. You can bet there is someone on this forum who has been there and done that, and we can answer all your questions when we have this information. You need to realize, however, that everyone reacts a little differently to even the same treatment. If you can also be more specific about the location of your OC, there will most probably be someone here who has had the same thing. Take a deep breath and hang in there. We will help you through this!
