Frostymug, I read the excerpt you posted and I actually agree with the author.
Candida Albicans is known to have the ability to turn into a fungus. It can assume one of seven distinct life forms. In one of these forms, Candida lacks a cell wall, and thus the immune system fails to recognize it as an intruder.
As for the fungal theory of cancer, I think it is time it was recognized as a fact. Treatments of terminal cancers by cancer specialists following this theory result in a survival rate of 80 percent, as opposed to 2.7 percent for all cancers treated with the standard mix of nukes+chemo.
