Vitamin C kills cancer, I THINK that if you just take a good bit of it on a daily basis, it'll stave off cancer and you probably won't have to worry about getting it. You CAN'T take too much vitamin C! If you get cancer anyway, start taking vitamin B17.

Actually, Vitamin C isn't exactly harmless. I know Linus Pauling advocated doses of 10 grams or more per day, but at some point it does leech calcium from the bones and can cause kidney stones, not to mention it can cause all kinds of gastric upset (nausea, vomiting, diarrhea, abdominal bloating and cramps), headaches, and insomnia. http://www.mayoclinic.org/vitamin-c/expert-answers/faq-20058030 (Btw, I don't believe it is possible to get adequate nutrition from any kind of diet consisting of foods grown and harvested commercially, thus I do disagree with most dietitians and would recommend everyone take a good multivitamin as well as extra C and other things.) Also keep in mind refined foods deplete vitamin C. A single chocolate chip cookie can wipe out whatever vitamin C you have in your body (or so Durk Pearson and Sandy Shaw once claimed).

Vitamin B17 is questionable at best and deadly at worst. I'm not sure why I tend to trust Dr. Andrew Weil, but he calls B17 dangerous and potentially deadly, not to mention stating there is no evidence it fights cancer. http://www.drweil.com/drw/u/QAA400624/Do-You-Need-Vitamin-B17.html
