I don't know anything about the machine I'm sorry. Chemo works on blasting ones immune system and working to kill the cancer cells. It's a poison. Usually healthy cells will recover, cancer cells not so much. I am ot sure what kind of chemo she's on, and I am by no means an expert - but. Think the reason it's hard to do surgery after chemo is because of the chance of infection... Compromised immune system and all, but I would ask an expert. It is the same with operating on radiated skin. Apparently this is also is hard. The radnseeds may help her. She sounds healthy - otherwise. Is there no place perhaps another country nearby that she could go to for her surgery?

Best of luck.
