So methods I've heard of that help and or have cured. Again I personally don't know the who's/if/where's other than testimonials I've seen or heard about. But these are things I'd look into if ever faced the evil beast.
-salvestrols
-apricot kernels
-raw food diet
-the chilli habanero cure
-burnski
-hoxsey cure
-rife
-baking soda molasses
-barley grass
-Gerson therapy
-black seed oil
-hydrogen peroxide
-graviola
-iodine
-faith healing
-selenium
A couple of things I've learnt recently. We must have selenium in our bodies, 4 Brazil nuts a day should cover this. High dose selenium supps can be toxic but food based supplementation not. We need iodine too - big time..

I dunno it's a tough scary subject.
I personally met a woman a few days ago who walked away after chemo and rad failed and her C came back worse and spread to her thyroid. She took high dose iodine and cut all grains out of her diet completely. Eats healthy and kept eating dairy funnily enough but she's still here two decades on c free.
