To do radiation or not

With radiation,you can never tell who will burn and who won't. I'm fair and just ended up glowing like a hot plate but my skin never broke down.I'd had a lumpectomy and so radiation was a done deal- I didn't think much about.When cancer came back in the same spot 7 years later,I really questioned the radiation.I had to have a mastectomy and can't have implants because my skin is so tight from radiation.I also have upper lung scarring. Every bc treatment carries risks but then not doing it risks recurrence or worse still,metastasises.It's a balancing act .All you can do is gather the info and stats. Get a second opinion if needed and then go with a decision that feels right for you.
