Welcome to the wild west! I would think carefully about how much of my time I want to spend here if I were you!!!
My dad passed away from cancer almost 10 years ago; doctors gave him a 6 month "death sentence" which he fought off for 5 years.
Steve Jobs thought he could "new age" his cancer away. Didn't work.
I have recently, however, come across http://nutritionfacts.org/, and its proprietor "Dr. Greger" shares a similar story about how his mom got cancer, and that is why he started the site. He basically says: Don't eat meat.
I think what killed my dad was vitamins, after several rounds of chemo he was clean. He eventually took vitamin supplements, and the cancer relapsed with a vengeance.
