Not being able to start on chemo or radiation may be the best news he could have. The oxygen he is taking is likely to do far more good than any evil mainstream regimen of chemo or radiation.
My uncle is 85 and he had lung cancer last year that the oncologists assured him would be eliminated with radiation but wasn't and instead continued to grow and spread to other parts of his body. When they recommended even stronger radiation plus chemo, he instead began taking the oleander extract mentioned in my above post (http://curezone.org/forums/fm.asp?i=1081775#i) and following other parts of my recommended protocol and within only a few months was cancer free and back to enjoying a round of daily golf.
