I have been doing a lot of research since my husband was diagnosed, and discovered diet plays a major role. Animal proteins are bad for the body, and a vegan diet is best to keep cancer cells from returning. Since there is no "cure" for cancer, we have to keep it away as best as possible. We are what we eat. It is not a cure for cancer, but from what I have read, and saw documented, one can live a longer life if they develop a plant based died.
