I personally went through cancer back in 1997-98 and I went through radiation. For me *PERSONALLY* I have chosen and made my wishes very clear, that I do not want Chemo. I have seen too many people have their life extended by a few months, but those few months are pure hell. Being sick etc. It isnt what I want for myself.
Again, this is me (Rick) speaking for myself, I am pretty sure I would make the same choice for my bullies.
Good luck, and I don't envy you with these decisions
