Kellum therapy is one known to work at stage 4 on 12 different types.....consists of nothing more than pure maple syrup and baking soda, recipe is simple 1 teaspoon of syrup , with 1/3 teaspoon of baking soda ,taken 3 times daily , morning ,noon and night.
for topical cancer : equal parts of baking soda and molasses mixed together and applied to the area for 2 to 3 weeks until no longer visible, then continue for another 2 to 3 to make sure theres no root ,as per dr.simoncini
