Hi @Judithm,
It is bloody awful how many decisions you have to make through this when your brain appears to be somewhere else. My situation was a little different but as I was adamant about having the lumpectomy vs mastectomy I had to have the radiation.
I really didn't find rads much of an issue at all. No fatigue, minimal skin problems.
It's almost two years since I finished radiation and the only side effects that are apparent at the moment are a little heat in the area at times and the occasional ache where they nuked my chest nodes. I just have to be a bit careful in the sun.
Good luck with your decision.
