Quote from Yisterwald:
My mother-in-law tried your buddy's plan with cancer.
She's dead.
My next door neighbor had cancer. He went all-out with fasting (30 days), faith, herbs, anti-oxidants, organic, body-work, pilgrimage, ...
By the time, he put himself into professional hands, he was a lost cause. They gave him some chemotherapy, but these things are targeted. They only had once shot, and he was so weak from fasting, that it wasn't much of a shot.
Even as he was laying there at imminent risk for side-effects, his wife was still insisting on organic homeopathic "remedies."
For every case of cancer being cured by alternative medicine, there is probably a case of it going into remission by itself. Don't take chances. The drugs work. They do what they are supposed to do. They can do lots of other bad things as well, but they are potent. The tea leaves sitting on the shelf at your herb shop have been sitting there for three years and came from a plant with little quality control.
Be your own advocate, but use the tools and technologies available.
