I feel for you, @Della - I was lucky & didn't have to make that choice, but we DID make that choice for my husband as his cancer was aggressive & altho it was 'only' found in the 1 lymph node .... that was enough! As @Sue_w says - the chemo is to mop up the randoms, much the same as the radiation does (I did 4 weeks of radiation) ...
They are much better at chemo doses these days too - not everyone loses hair etc, tho some do.
It is a tricky one ..... it is all about the 'what ifs' ...... what if it comes back and you hadn't had the chemo?
I know that I would have done the chemo if it was suggested to me .... as I wanted to throw everything I could at the beast .....
Don't believe all the 'quack' stories on the web - just as many vegetarians get cancer as anyone else ..... just eat well but not too much, exercise normally & keep busy & make a life .....
