I am sorry to hear about that rottielover33!
I know what chemotherapy can do to someone, my brother had leukemia and he died from an infection he caught in the hospital just before he was to have a bone marrow transplant. He had endured many rounds of chemotherapy and more than that. It was quick too, he had an infection in the mouth that would not go away so our dentist told him to go in the emergency room and after a quick blood test he was told he had leukemia.
These diseases are very nasty, it sure would be nice if one day one of them had a cure, looks to me like they are not working very hard to find these cures, I will not be surprised if one of these days we learn that there were cures but they decided not to let them out, I hope I am wrong.
