The cancer salves use an acid, that is their key secret. I have some cancer salve books, I forget their name. The book tells the history of cancer salves and all the formulas.
Sunshine is the strongest healer in all cases, especially cancers. A poor mans method is cold water. If you keep a wet cold water rag on a tumor for 10 straight days it is said to cure it. Naturally the water cures nothing, it is the reaction of the body that does all curing.
I suggest the old Christopher method, I have seen it work, he suggested you take all your cloths off, take a quart of grape juice and take a long walk. The reason this works is your not eating and allowing the Sun to kill the fungus in the body naturally and charging your cells all for free!
Remember also, all cancers have one thing in common, low potassium and high salt.
