Your sister can remove all toxic elements from her body. I'd suggest you to listen to the doctor's advice about raising of Glutathione level (which is responsible for the immune system) naturally for people who have cancer cells or recuperated from the toxic chemo- or X-Ray therapy. Your body will be able to get rid of all the toxins or heavy metals very fast. Cancer could be treated in the same time.
