DQ is right.
Cancer is helped a little with survival of over 5 years being considered to be a "success" and cure.!!!
However, these cure rates do not apply to cancer that has metastasized, where mainstream medicine has very little if any success at all, and where the survival rate has not changed over the last 30 years!!.......source.......www.curecancerproject.org and this with a total overall investment of $200 billion on cancer research.
Wonderful success rate isn't it?
