I can't help with all of the facts and statistics (there are many here who are WAAYYY more qualified for that than I) but I might be able to help a little bit from a different perspective since I've been dealing with various issues of illness for the past 20 years (I was diagnosed with MS at 19)

I think Charm mentioned a very valid point "if the cancer comes back, will you regret not having had the radiation?"

The only thing we can do is obtain all of the information possible and then make the decision that is right for US--because that decision is different for everyone--then if the information changes, re assess, and make a new (or not) decision based on the new information. Make peace with that decision, whatever it may be and know that it was the right decision for you whatever the future holds.

I had to make some really difficult choices regarding the treatment for my Multiple Sclerosis (potentially life threatening) I made my choices, made my peace with them-and never looked back. Trust me, I had family member who had serious issues with my decisions... We have enouph problems without second quessing the future. I had to make the same type choices regarding my cancer. Talk to the person/poeple whose lives are mostly closely linked to yours (mine was my husband) and do what's right for you.

Be well,
Michele
