Pancreas and Small Intestine

Pancreas and Small Intestine

Can osteosarcoma in dogs, bone cancer, or any other cancer, be caused by a lack of pancreatic enzymes?

Substantially correct, indicates Dr. William D. Kelley in his book One Answer to Cancer, “At least 86% of all cancer conditions could be adequately treated and/or prevented by diet and pancreatic enzymes.

He explains, “Cancer is a symptom of inadequate and deficient protein metabolism. The real problem is protein metabolism, not cancer. Cancer is only a symptom telling those who would listen that their protein metabolism is in very serious trouble. Surgery, radiation and chemotherapy only treat the symptoms of cancer.”

This has been known for one hundred years when embryologist Dr. John Beard at the University of Edinburgh found the body’s primary mechanism for destroying cancer is contained in a digestive secretion from the pancreas, called pancreatin.

To explain “general systemic condition” as opposed to “symptom,” let’s look at pellagra, diabetes, and cancer, all deficiency diseases, according to Kelley.

Before it was known that pellagra was a simple vitamin B deficiency, pellagra patients were placed in insane asylums by their physicians. In 1916, Dr. Joseph Goldberger found that diet could prevent pellagra. And in the 1940’s, it was discovered that pellegra could be resolved with B vitamins. Now instead of being locked away, pellagra patients were given B vitamins.

So pellagra is a symptom of a general systemic condition. The condition is the lack of B vitamins. But for centuries, only the symptoms were treated.


What is Diabetes?

Also nothing more than a symptom, diabetes is a symptom signaling the systemic carbohydrate (sugar) metabolism is off due to either a lack of insulin production or utilization.

Before Professor Ernest L. Scott discovered insulin in 1911 and up until the early 1930’s, a person diagnosed with diabetes would be told that diet didn’t make a difference in their diabetic condition. The connection just wasn’t made. But lay people figured out if they ate a lot of leafy greens and reduced their sugar intake, survival rates seemed longer and those who practiced dietary restrictions did better than those who didn’t watch what they ate.

It wasn’t until after the development of insulin that the doctors figured out that diet was involved. They also saw their patients eating leafy greens and a few other foods survived diabetes much better and the patients’ urine sugar count was also much better.

We’re in the same place now with cancer. We’re waiting for the medical community to realize that diet makes a huge difference in people with cancer.


What is Cancer?

Cancer is also nothing more than a symptom signaling our systemic protein metabolism is lacking proteolytic enzyme production or utilization.


The parallels between insulin and proteolytic enzymes are interesting:

  • Both insulin and protein digesting enzymes are made in the pancreas.
  • A neurological process controls both insulin and enzyme production.
  • Both diabetes and cancer can often be controlled by diet alone.
  • Diabetes can almost always be managed with the right insulin dose. And cancer can usually be managed with the right dose of proteolytic enzymes.
  • Both diabetics and cancer patients can live long, productive lives and not die as a result of their diseases.
  • Both a diabetic patient and a cancer patient must control their diseases for the rest of their lives with diet or medication or a combination of both: the diabetic with diet and insulin, the cancer patient with diet and proteases (proteolytic enzymes).
  • Both diabetics and cancer patients need professional assistance to determine, as well as regulate, their conditions. But it’s the patient’s responsibility to administer the proper diet, medications, and/or nutritional supplements to his or herself.

Kelly, with his overall Metabolic Medical protocol, claimed a 93% success rate with cancer patients. The Budwig Center includes dietary enzymes in their treatment, and Dr. Nicholas Gonzales, currently practicing in NYC, uses, and has built upon, the Kelley digestive enzyme metabolic protocol, has treated Stage IV pancreatic cancer patients, among others with amazing success.

Pancreatic Amylase

Pancreatic Amylase


Amylase and Trypsin

Note: The total complement of digestive enzymes are important in a cancer program. This includes amylase. While most enzyme therapies focus only on protein digesting enzymes, according to research, amylase is also very important. It suffuses the carbohydrate cell mask that surrounds and protects the tumor from being attacked by the protein digesting hormones. Amylase, along with trypsin, disarm the hormone hCG which acts as an inhibitor of protein digesting enzymes.

Bovine Trypsin

Bovine Trypsin





Also note: While many articles refer to injectable enzymes. The enzymes function when taken orally.



Below is a simple video reminder of the functions of amylase, lipase and protease.
