Unleashing the Power of Enzymes in Fighting Cancer

If you’ve read my book, I Used to Have Cancer, you know that I believe that enzymes are one of your best defense mechanisms against cancer.

In fact, if you have cancer, you can almost bet that your enzyme reserves are deficient. And should you know that it’s surprisingly simple to balance the scales and improve your odds of surviving the deadliest of cancers.

Modern science is at last proving what the early pioneers in this field tried so hard to tell us.

Pioneers of Enzyme Therapy

It was Dr. John Beard, Scottish scientist and professor, who first discovered what he considered to be the origin of cancer. His work led to the pioneering of the science of enzyme therapy. Yet despite being nominated in 1906 for the Nobel Prize for his work in embryology, Beard’s work was considered by many of his peers to be controversial. Why?

In 1911, Beard published his book, The Enzyme Treatment of Cancer and Its Scientific Basis, detailing the compelling results of decades of research. Unfortunately, it was no match for the popular claim at that time by Madame Marie Curie that radiation should be the preferred cancer treatment. Radiation was initially said to be non-toxic, though we now know that it not only is it highly toxic, in actuality, cures few cancers. Madame Curie herself fell victim to excess exposure to radium. Her research notebooks are still so contaminated that they remain stored in lead-lined boxes even today.

Dr. William Donald Kelley (1925-2005) picked up the mantle of Beard’s enzyme therapy hypothesis and became one of the more well-known practitioners of enzyme therapy in his time, particularly after treating movie star, Steve McQueen, for mesothelioma. Kelley’s book, Victory Over Cancer: Curing the Incurable, was a product of 50+ years of planning for the treatment of 33,000 patients. In it, Kelley outlined his protocol for the use of enzymes, specifically, in treating cancer. While his work remained controversial during his lifetime, others who came after him took up the cause and expanded on Kelley’s work.

One notable practitioner who made headway in pancreatic enzyme therapy was Dr. Nicholas J. Gonzalez (1947-2015). Gonzalez was successful in treating his patients diagnosed with cancer and other serious degenerative illnesses during his 30+ year career while in practice in New York City. In 1993, Gonzalez was invited by the NIH (National Institutes of Health) to present select cases from his practice. Remarkably, the published study concluded that pancreatic cancer patients (Stages 2-4) on the Gonzalez treatment regimen had a nearly 3x survival rate compared to those who did not receive the treatment.

Today, enzyme therapy is recognized as a viable cancer treatment especially in European countries, while more and more holistically-minded practitioners here in the U.S. are acknowledging its value. By simply supplying your body with the nutrients it needs and may be deficient in, this natural treatment is still making waves in the treatment of cancer.

How Does It Work?

When your body is in top shape, it successfully fights off cancer cells each and every day… even though you’re unaware of the battle going on within. However, when your immune system is impaired for any reason – including stress — cancer cells can abnormally suppress your body’s natural immune response, and that’s where the problem starts. Left unattended and without proper nutrients, the cascade of events that often follows can lead to the dreaded, “You Have Cancer” diagnosis which an estimated 1,806,590 patients fell victim to in 2020 alone (National Cancer Institute). Unfortunately, that number continues to grow.

Enzyme therapy naturally stimulates your immune system, allowing your body to fight back against the assault. An article published in Medical News Today (How One Enzyme Could Stop the Spread of Cancer) reported that scientists “have identified a new enzyme mechanism that induces cancer cells that are about to migrate to destroy themselves by degrading their tiny powerhouses, or mitochondria.”

Pancreatic enzymes stop tumor cells from dividing. It’s a much more humane way to stop the growth of cancers cells than chemotherapy. Patients who opt for enzyme therapy are typically prescribed large doses of enzymes, vitamins, and mineral supplements in addition to a diet free of highly processed food. The enzymes are used to directly attack the cancer, while the diet and vitamin supplements are a viable method of strengthening the immune system. Detox routines, such as coffee enemas, are also an important component of most enzyme therapies.

We have no doubt that further research will prove what the pioneers of enzyme therapy knew all along. Enzyme therapy is a powerful tool in the fight against cancer.

Listen for Yourself

Recently, I was fortunate to interview Dr. Linda Isaacs who worked with the late Dr. Gonzalez for over 20 years. In addition to co-authoring books with Gonzalez such as The Trophoblast and the Origins of Cancer, she has written several papers published in medical journals.

The Gonzalez Protocol is a remarkable regimen of personalized diet and supplement recommendations, along with valuable detoxification routines. The addition of coffee enemas, for example, is an extraordinarily helpful component that, along with enzyme therapy, helps the liver detox from excess toxicity.

Outside of sitting down with Dr. Isaacs in her office, there may be no better way to learn the truth about the effectiveness of enzyme therapy than by watching what I think you will consider a very enlightening interview.



I also encourage you to check out my interview with cancer survivor Ann Cooper who beat a Stage 4 Pancreatic Cancer diagnosis with enzyme therapy and coffee enemas. She avoided the surgery she was prescribed and opted instead for alternative treatments. The results speak for themselves.
