Hi, I'm a cancer survivor. Hodgkin's Lymphoma in my chest, two big tumors which responded very well to chemo and no radiation because of he location (heart/lungs). I did not yet know I had Asp at the time of my dx. though. I remember treatment being a very overwhelming and confusing time. My ordinarily excellent memory was replaced with forgetfulness and what seemed like apathy. I do not envy you and the choices you are faced with and I have often wondered what I would do were I to relapse. It would definitely depend n the type of cancer and the odds, 5 year survival rate, etc... Then again,maybe it wouldn't. People can say what they think they will do, but no one knows for sure until it's real.
I am thinking of you. I'm sure this is such a stressful time. Go YOU, whatever you decide, you are a warrior!
