Is this article just a scam?: http://gerson.org/gerpress/how-im-conquering-prostate-cancer/. if so or if not, how can it be proven? i need some proof.

Looks deceptive.: Unfortunately, there are many sites that claim miracle cures for cancer with no real data. This site makes some very bold & dubious claims, while charging hundreds of dollars in registration fees for seminars. As a physician & cancer researcher i cannot endorse this as anything but fantasy. We must rely on science & well designed clinical trials to develop & test real treatments , not false hope.

Old cruel scam: Max Gerson was one of the early 1900's greatest cancer charlatans. He was a sweet-talker offering basically nothing of value but human warmth. You won't find proof -- people go to the internet to find hope, and there are plenty of people offering false hope. Many of them are even self-deceived.
