@Bravo I had 25 sessions and only towards the end was there a problem I remembered talking to the radiation oncologist about skin reactions. She stated that some people with fair skin do just as well as people with say an olive skin. She stated it depended on each individual persons reaction.
So you may be lucky it is not inevitable you will have problems.
Compared to chemo for me radiation was good though I did progress from sorbelen to burn cream. Healed well in a short time and glad it is all over
