I recommend doing some research on diets. Of what to eat and not to eat. Definitely avoid stuff like high fructose corn syrup, aspartame, monosodium glutimate, fluoride, lithium, heavy metals, etc. The best thing to do is look for organic meat and veges. Non gmo.
Some times the best thing is a raw vegetable diet. But it differs per person.
Look into Vitamin B17 and apricot seeds for cancer.
I've also read that baking soda mixed with honey and molasses can help.
Look into Spirulina and Chlorella which are complete supplements, and which are natural algaes.
But try seeking natural remedy while seeking medical attention.
