An innovation in cancer care using insulin to magnify the powerful cell-killing effects of ordinary chemotherapy drugs, which can then be used in very low doses. Because cancer cells have so many more insulin receptors than normal cells, insulin acts on them much more strongly. The end result here is that the chemotherapy drugs get effectively targeted just on the cancer cells to kill them, with little or no effects on normal tissues. Thus IPT can avoid the dose-related side effects of chemotherapy. One of the clinics using this approach is Contemporary Medicine, run by Dr. Steven Ayers.
