May I caution against some of the websites out here in the ether? The Cancer Council and some reliable hospitals are your better bets. While it may be counter intuitive that poisons can cure you, some of us are proof that they probably can. When there is substantiated proof that you can eat your way to a cancer cure, we will all be delighted. By all means discuss your eye specialist's caution with your oncologist, seek a second opinion if necessary. But beware Dr Google.
