auOrei Hi If I had a choice I would not do radiation.
In my case I was told I would reduce my reccurrence of cancer by 70percent. I also had to have radiation in the neck . I had few side effects .Minor burns in the last weeks . I became increasingly fatigued. My energy levels are nowhere near normal. I am feeling generally fine.
So if an oncologist is suggesting to not proceed then maybe you are doing the best for yourself by not going ahead. Lettting your body heal is very good medicine. Not everyone has or needs radiation .I found radiation so much more easier than chemo . It is your decision.
