<unk>  is being studied/used in the treatment of cancer to avoid the devastating side effects of conventional chemotherapy. Historically, oncologists have used the highest possible<unk>  that the body can tolerate in order to kill as many cancer cells as possible.
After high-dose treatments the body reacts, sometimes quite severely. Unfortunately normal cells, vital organs and the immune system often cannot tolerate the chemo's poisonous assault. Infections from external causes become a leading threat of death.
Some major pharmaceutical companies have spent hundreds of millions of dollars to get FDA approval for drugs to restore cancer patients' immune system.
