If it was me I would juice fast, load up on barley greens and take Bentonite three times a day. It will make the body sick at first there will be throwing up and all kinds of terrible side effects as the body detoxes but hopefully the Bentonite will absorb most of the toxins and move them out of the body as it heals. That is what I would do. You and others are free to decide for yourself. Chemo and radiation are acidic and toxic and actually cause cancer and I would never ever take that myself as modern medicine is fixated on profits and has no clue how to treat cancer.
