The Overview




  • An evil witch or diabolical sorceress that nonchalantly wanders around seeking innocent victims to destroy
  • A mystery beyond understanding
  • A disease for which we know no causes
  • A disease for which there are no good answers or cures
  • A disease only medical doctors know how to treat and control
  • A disease to fear and dread
  • A reason to give up on life and living
  • A tumor

Cancer does not just happen. Normal healthy cells don't just spontaneously metamorphose into abnormal cells unless deprived, debilitated, poisoned, and damaged.

Cancer is the sum of all the processes which transform normal, healthy, alive, cells into abnormal, damaged, denatured, and toxic cells. Tumors are merely the end result of this process. Tumors are not the cancer. The process that creates the tumors is the real cancer.

Cancer is a disease of cells. Understanding cancer is understanding cells. Treating and curing cancer is treating, normalizing, supporting, sustaining, nourishing, protecting, and regenerating cells.

The study of cancer is the study of all these points. Medical research, over generations, has progressively unveiled the secrets of the world inside living cells -- secrets that have kept us in ignorance about cancer for centuries. There is no more mystery about cancer, but there are many complexities.

Cancer, in each patient, is the sum combination of a body's cells' reactions to all the chemicals, drugs, pollutants, and radiations that saturate our environment and of all the stresses, hazards, and abnormalities of our lifestyles and our civilized conditions of living.


Cancer Is Preventable, Treatable, Conquerable, and Curable

Believing that cancer is beyond the abilities of science and doctors was justifiable during the centuries when we knew little or nothing about cells, their physiology, their biochemistry, and the impact that chemicals, drugs, and radiations have on them.

We are no longer in the dark ages of science. The era of cancer ignorance is past. Libraries of information exist about cells, their nature and functions, how they multiply and divide, and what agents control cell proliferation. It is no longer justifiable to claim that we don't know the nature and causes of cancer.

It is true we don't know "the" cause or "a" cause for there is no such thing as a single simple cause. There are only multiple causes. Cancer is a complex illness. By correlating all facts and causes together cancer becomes understandable.

It is only as we allow our minds to be mesmerized by the misconceptions of past centuries that we have difficulties accepting and mastering the realities of cancer. We need to take a look again at the whole cancer concept with minds completely free from beliefs and conclusions procreated in the centuries of ignorance and to replace these misconceptions with the scientific discoveries of the last fifty years

Clear, common sense and realistic awareness of everything about cancer can cancel out your fears and replace them with assurances that there are a multitude of answers that make possible the overcoming of cancer.


Cancer Is a Disease of Cells

Cancer is the sum of poisons, attackers and abnormalities that transform normal cells (such as the one illustrated below) into biochemically distorted, abnormal, and sick cells (such as the one illustrated on the next picture).


Cells are molecular structures of proteins, minerals and trace minerals, oils, and thousands of enzymes. Cell nuclei house chromosomes. These govern and control the life, functions, growth and dividing of cells.

Cells are surrounded by, and float in, body fluids, like fishes in an ocean. In constant contact with all the substances in those body fluids, they are subject to chemical reactions with them. Anybody with high school chemistry knows that it is not possible to place two chemicals of radically different natures in contact with each other without each reacting with the other. Everything in our bodies, tissues, organs, fluids, and cells contains chemicals. They are vulnerable to chemical reactions.

If the inner body environment, or "ocean," is healthy, the cells will remain healthy. If the inner body environment is polluted and full of poisons the cells will eventually be damaged by those poisons.

Nature has created an almost impregnable and formidable protective suit of armor covering of cells -- the cell membranes. As long as cell membranes are healthy and intact, cells resist all invaders and attackers.

Cell membranes are also made up of proteins, oils, minerals, and lecithin. They control cell nutrition by selectively allowing the absorption of molecules only, which are identical to those which original form their structure. They repel and reject all substances of a nature different to their own special biochemistry -- including poisons and carcinogens.

Deficiencies, denaturing, and deterioration of its membrane is the start of cell disintegration and of its transformation into a cancer cell. It is only when cell membranes succumb to reactions with the toxic chemicals, in which they are immersed and become chemically damaged, then they lose their power to defend themselves and block the infiltrating of poisons and carcinogens, which pierce the membrane barrier and enter into the cell protoplasm. They react with, destroy, and displace the cells organelles, enzymes, and other cell components. Cells lose their identity and become cancer cells.

It may take years for body pollutants and poisons to damage, break down, and destroy cell membranes.


Possibly the most powerful and effective protector of the structure and functions of cells against attackers and invaders are their membranes. Membranes also play a major role in the control of what cells absorb, and in the control of cell growth, cell division and multiplication. By powers of a magnetic attraction, cell membranes act as the gates whereby needed nutrients enter into the cells.

The cell diagram on the previous page shows a damaged membrane pierced in many places. Many of its inner structures have been denatured and destroyed. It no longer functions in its normal ways. This picture is typical of a cancer cell. As cells become over filled with excesses of any kind, they swell beyond their normal size. When close to double in size, they normally divide into two cells. Their excessive proliferation creates masses of billions of cells. These are tumors.


The Nature of Cancer Is the Nature of its Cause

Cancer societies and medics constantly promulgate statements that we do not know the causes and nature of cancer. Yet you can read about them in your newspaper and hear them on T.V. They are listed in journals of toxicology. They are no secret; they are no mystery; they are the key to understanding cancer.

In all cancers there are three categories of causes.

  1. Predisposing causes: those which weaken cells and their resistance to disease.
  2. Contributing causes: those which overload body organs, cells, the organs of detoxification and elimination, and hinder them from metabolizing toxins and wastes.
  3. Triggering causes: Highly toxic substances which denature, damage, and transform normal cells into cancer cells. The most lethal of these killing agents are termed carcinogens.

(You are not expected to read in detail or remember the long list of causes that follows on the next page. Skim over them quickly. You may not know the chemical names. They are known to chemical scientists. This list is to make you aware of how many known causes of cancer we constantly live with in our civilization.)

  • Loss of the will to live


The list above of scientifically proven causes of cancer tells us that the problem of cancer is NOT that of NOT knowing its causes . The problem is that we know too many. Those who succumb to cancer are generally affected by many causes. The most common of these conditions that most people live with year in, year out, are listed below.



  • Excess histamines
  • Excess sodium -- loss of potassium
  • Overactive pituitary gland
  • Toxin absorption; like fat cells that store excesses / wastes
  • Excess nutrient intake, water intake, and overeating
  • Hyper thyroid
  • Over-alkalinity of body fluids -- over-saturation of potassium from excess dying of normal cells
  • Acids. Excess intake of acid foods
  • Caffeine and caffeine rich foods; they over-activate the metabolism
  • Excess cell death activates excess cell replacement through cell growth and division



  • Antihistamines
  • Acidity. Balanced normal level of body acids, hydrochloric, phosphoric, and ascorbic acids
  • High activity: burns up and catabolizes cells as fast as they can reproduce and grow
  • Pituitary inhibiting hormones
  • Oils. Cell coating and protectors
  • Plentiful enzymes resources. Eat enzyme-rich foods in their natural, alive state.
  • All drugs and radiation



A good number of the following are conditions that constantly affect our lives, our health and our cells.

  1. Hereditary preconditioning
  2. Stresses of every day living, tensions
  3. Work overloads and pressures
  4. Shocks, emotional trauma
  5. Grieving, serious losses, loneliness
  6. Hatred, angers, fears, phobias, and anxieties
  7. Fear of cancer
  8. Negative attitudes and demoralization
  9. Low self image and self-hatred
  10. Exhaustion and devitalization
  11. Inadequate rest, relaxation, and poor sleeping habits
  12. Lifestyle excesses and abuses
  13. Poor or blocked local blood circulation resulting from lack of exercise
  14. Natural gas, air conditioning, traffic or industry fumes, low oxygen levels in the home or office environment
  15. E.L.F. High-tension lines
  16. Radiation supersaturation and radon areas
  17. Any, or many, of up to 1,000 carcinogens in foods
  18. Carcinogens in water: fluorides, chlorine, Dioxin, P.C.B.s, plumbing and water treatment chemicals
  19. Routine intake of an assortment of medical drugs
  20. Hereditary imbalance of the endocrine glands
  21. A hydrochloric acid deficiency, with fault digestion
  22. Inadequate functions and secretions of the pancreas
  23. Toxic, overloaded, and under-functioning livers
  24. Lowered immunity and resistance to disease
  25. A general imbalance of all body biochemicals and pH
  26. Poor diet resulting in overcooked, enzyme-depleted, toxic, dead, and counterfeit, bankrupted foods
  27. Excesses of denatured, overcooked, and microwave proteins,
  28. Vitamin deficiencies
  29. Mineral-trace or mineral deficiencies
  30. Long term, deficiency of essential protecting oils
  31. Excesses of toxic, stale, or hydrogenated commercial oils
  32. Accumulated body wastes, retained by constipation
  33. Little or no joy of living, or hope for good living
  34. T.V.s or computer monitors

The cancer process is a battle between cell attackers and invaders and cell protectors and defenders. This process is illustrated on the next three pages.



In the presence of carcinogens our bodies become battle grounds. Cells struggle constantly to protect themselves against chemical enemies, biochemical deficiencies, and imbalances that threaten to destroy them.

Cancer cells cannot survive and grow except by feasting on excesses of pollutants and poisons that saturate the fluids in which they are immersed.

There is no specific entity called "cancer." There are only people who have succumbed to the processes which create cancer cells -- those whose bodies have lost the ability to neutralize and get rid of all the chemicals, poisons, and carcinogens which damage cells.

If these are not detected and unveiled, what is not known, of course, assumes the semblance of being a mystery.

Almost nobody succumbs to cancer unless they have been affected by many of the causes listed on pages 17 and 18.

Individually, each cause may be simple and not serious in nature.

The sum total of all causes together becomes a destructive process. The assortment varies with each person. What causes one personís cancer is not likely to be the same combination of causes that destroys the health of another.
