Good for you for shopping around for the right fit with your oncologist. I am a decade younger and unfortunately, was not able to tolerate chemo so stopped. But that said, I saw plenty of older people in the infusion center doing just fine. I think it is an individual thing. In contrast, radiation was a breeze for me. One thing to keep in mind is that you may be at higher risk for certain side effects of certain chemos after doing rads - at least, per my radiation oncologist. Oncologists like to do the treatment in a certain order - chemo first, then rads, etc. I don't know that this is a hard and fast rule, though, but something to ask about. I have seen patients get chemo and rads at the same time.
