Thanks Tammy. The HBO I can and can't understand due to reading, hearing conflicting reports. They use HBO to treat hypoxia, so one is not chemo or radio resistant, but is not too beneficial. They also found that tumors thrive in low oxygen from angeogenisis (Sp) when they take new blood supply to grow. Anyway, I was too tired to even ask lol, and just do what the doctor says. I think I'll stick to cooking lol.
