This is an anecdotal cancer recover story that gives methodology. Just for reference. The guy became famous. One thing seems quite certain is: Fasting is very beneficial to body during chemo. (Not quite well explained in this interview but there are a few other interviews with the same guy). Hope it's useful
That video interview is so valuable, by presenting a real case, that was successful in beating cancer, with some novel approach. It's good for people to be aware of this. This is not about Eric Berg.
