Pathophysiology • Normal cell growth, development and replication is governed by multiple cellular control mechanisms • Mechanisms are programmed through genes • Malignancy caused by mutations in genes that encode these control mechanisms Graphic taken from wikipedia Pathophysiology • Unlike other diseases, cancer is not limited to a certain part of the body • More than 200 different types • Malignant cells characterized by – uncontrolled cell growth and aberrant function – Aggressive/invasive behavior • Different from benign tumors which are limited in growth and are non-invasive (although some benign tumors can become malignant under the wrong conditions). – Source: WHO Pathophysiology • Mutations in genes that encode cell growth control mechanisms lead to malignant cells that share 6 characteristics: – – – – – – Promote their own growth Insensitive to growth-stopping signals Evade apoptosis Promote angiogenesis Become invasive/metastasize Can multiply forever • Source: “The Hallmarks of Cancer,” Hanahan & Weinberg in Cell, Vol. 100, 1/7/200 Epidemiology • Cancer causes about 13 % of deaths world-wide and this incidence is rising. • Cancer is the second most common cause of death in the US (after CV dx), accounting for nearly 1 of every 4 deaths • From 1950 to 1991, cancer incidence increased by nearly 50% with mortality increasing by more than 10 % (adjusted for aging and growth of the US population) – – – – 550% increase in lung cancer in women 350% increase in malignant melanoma 200% increase in multiple myeloma 190% increase in prostate cancer • Sources: WHO, NIH Epidemiology • • • • • Median age of diagnosis: 67 5 year survival rate is a misleading statistic Lead time bias Selection bias In the US, men have slightly less than a 1 in 2 lifetime risk of developing cancer; for women, the risk is a little more than 1 in 3 • 90% of all deaths are the result of metastases – Sources: national cancer institute’s SEER program, Scientific American Characterization • Carcinoma/Epithelioma: begins in a tissue that lines the inner or outer surfaces of the body (80 % cancer deaths world-wide). • Sarcoma: originates in connective tissue: bone, cartilage, fat, muscle, vascular, etc. (occurs more commonly in children then adults) • Leukemia: starts in hematopoietic tissues (bone marrow) and results in increasing numbers of immature white blood cells to enter bloodstream • Lymphoma: begins in cells of the immune system (includes Hodgkin's and non-Hodgkin's lymphoma) – Source: National Cancer Institute Etiology • Primarily a lifestyle disease (90-95% of cancers are lifestyle related) • Contributing factors include: – – – – – – – poor nutrition/obesity physical inactivity stress infections tobacco use environmental toxins radiation exposure • Source: Anand P, Kunnumakkara AB, Kunnumakara AB, Sundaram C, Harikumar KB, Tharakan ST, Lai OS, Sung B, Aggarwal BB (September 2008).

Contributing Factors • Immune deficiency • toxicity and radiation • inflammation Immune Deficiency • poor nutrition (refined sugar and starches, etc. • Stress/insufficient rest • Pancreatic insufficiency • Drugs • Synthetic antioxidants • All weaken immune system, allowing cancer-causing pathogens to invade Epidemiological Data: Traditional Diets Prevent Cancer Dr. Royal Lee, 15 July 1959 • Refined foods cause cancer because they fail to supply essential nutrients (that protect genetic material) • Fat soluble vitamins (E,K,F) and cholesterol form shells that protect our genetic blueprints (in the chromosomes) Epidemiological Data: Traditional Diets Prevent Cancer Dr. Royal Lee, 15 July 1959 “Cancer is a peculiar development of civilization again. When Dr. Albert Schweitzer went to the heart of Africa as a missionary 25 odd years ago, he said there was absolutely no cancer among the natives. When civilized foods followed him into the jungle, why, cancer came with it. The natives never had cancer until they ate refined foods. Epidemiological Data: Traditional Diets Prevent Cancer Dr. Royal Lee, 15 July 1959 In the Hunza country in India, Dr McHarrison made the same statement. He said there was no cancer among the Hunzas: never heard of it. He was there for many years. [He was] the author of the celebrated book, Studies in Deficiency Disease, written in 1921. McHarrison said there was no cancer until they got civilized foods in those countries, except where the people where already on a deficient diet such as in the large cities. Epidemiological Data: Traditional Diets Prevent Cancer Dr. Royal Lee, 15 July 1959 When Dr. [Weston] Price made his celebrated trip around the world and came back and wrote his book, Nutrition and Physical Degeneration, he had the same story. Where ever he visited areas where people had their own locally-produced foods, there was no cancer. In the upper valleys of the Alps, where they had no good roads and people had to live on their own rye bread and Swiss cheese that they produced in their own little valley, there was no cancer. When they built a good road and brought in civilized food, they had to build a hospital to take care of the cancer victims and other disease that followed the use of the civilized food. Epidemiological Data: Traditional Diets Prevent Cancer Dr. Royal Lee, 15 July 1959 Stefansson tells us that the Eskimos had no cancer whatever until they brought in civilized foods. We have many reports from the old time doctors who studied the health of the Indians in this country and they said the same thing – that malignancies were practically non-existent among the Indians when they were living in their aboriginal states. Those are the facts.” Toxicity and Radiation • Foods (pesticide and chemical laden) • Pollution (air, water, smoking, asbestos) • Radiation: cell phones, x-ray radiation, etc. Refined Foods Promote Cancer Dr. Royal Lee, 15 July 1959 • “ This experiment has been reported in the Journal of Cancer Research. They took two-hundred test animals. They fed half of them natural foods; the other half refined foods, and then planted cancer in all of them. They got ninety percent takes (cancer cases) in those on refined foods, and those on natural foods threw out the cancer, and there was 100% resistance to the cancer; there were no takes. Refined Foods Promote Cancer Dr. Royal Lee, 15 July 1959 The experiment had been repeated on penitentiary prisoners who had volunteered for the purpose in Pennsylvania within the last few months. They couldn’t get cancer to grow in men who had been getting any king of reasonable diet. Of course, they didn’t have a group that they put on a highly deficient diet like they did the animals. But the normal individual is resistant to cancer – is immune to cancer – and he has to develop that susceptibility by many, many, years of refined food eating.” Refined Foods Promote Cancer Dr. Royal Lee, 15 July 1959 “Dr. Quigley tells us that when he takes his cancer patient, who has had an operation and had his cancer removed, and gets him to follow a natural food diet – eliminate all refined foods from his food pattern, and bake his own bread at home from fresh ground wheat – he said that in 25 years of experience he never had a recurrence of cancer among his patients who would follow that schedule. He also said that all the patients who refused to listen to his advice had recurrences. Refined Foods Promote Cancer Dr. Royal Lee, 15 July 1959 In other words, his experience was exactly the same as the test animals, and this is a very wonderful piece of scientific proof, because the patients that followed his advice after operations became immune, and those that didn’t follow his advice were still susceptible to cancer. And if you’re susceptible to cancer and you’ve had an operation for cancer it’s going to grow right back, because the surgeon can’t remove every cell; it’s practically impossible.” Inflammation • from poor nutrition (processed/refined foods, lack of essential fatty acids) • Smoking • “chronic inflammation can play an important role in the progression of some types of tumors from a pre-malignant state to full-blown disease.” – Source: Scientific American Sugar feeds Cancer • Malignant cells waste the body’s energy • This is why 40% of cancer pts. die from malnutrition or cachexia • Cancer cells need sugar to survive and grow • Thus, having a low glycemic index/load diet is essential to arrest cancer growth – Warburg O.

Lifestyle Promoting Cancer • Tobacco use causes 30% of all cancers • Nearly 25% of US population still smokes (25% of men and 20% of women) • Very conservative estimate:1/3 of all cancers are related to poor nutrition, physical inactivity, obesity, or other lifestyle factors – source: National Cancer Institute Other Oncogenic Factors • Overuse of pharmaceutical drugs (eg. Statins) • GM foods • Carcinogenic food additives, sweeteners • Xenoestrogens (eg. BPA) • Obesity – Dr. Michael Gaeta, DAc, MS, CDN Infectious Disease • 17% of all cancer cases (more than 1.8 million/year) are caused by viruses and other infectious agents. – Source: American Cancer Society • Immune system is key in cancer support and prevention. 3 Stages of Malignancy • Initiation: related primarily to toxicity (eg. exposure to carcinogens, radiation, etc.) • Promotion: related primarily to inflammation. Inflamed precancerous tissue produces signals that recruit cells that effect angiogenesis, allowing it to grow into a malignant tumor. • Progression: through metastasis – Source: Scientific American 3 Stages of Malignancy • “Genetic damage is the match that lights the fire of malignancy, and inflammation is the fuel that feeds the flames.” (Scientific American) • Chronic Inflammation can also damage DNA and other critical components of cells, contributing to mutation and cancer initiation. (MIT Biological Engineering Division, as reported in MIT News, 7/25/06) Inflammation & Cancer • To defend itself and promote its developments, tumors recruit the innate/inflammatory immune system. • Cancerous tumors are “wounds that do not heal.” (cancer biologist Harold Dvorak, Harvard Medical School) Chronic Inflammation & Disease • • • • • • • • Chronic inflammation also contributes to: Cardiovascular disease Diabetes Alzheimer’s disease Psychiatric d/o Allergies and asthma Endocrine and digestive d/o Chronic pain syndromes – Dr. Michael Gaeta, DAc, MS, CDN Wholistic Pillars of Support • • • • Detoxification Improve Immune Function Reduce Chronic Inflammation Change cancer promoting lifestyle patterns Detoxification • Whole food diet (no processed foods or sugars) • Regular exercise • Supervised detoxification/purification program • Smoking/recreational drug use cessation • Reduce daily chemical exposure • Have pharmacist do MTM to minimize carcinogenic meds SP Purification Program • Simple diet • Regular exercise • Whole food nutrition / herbal medicine Immune System • Innate Immune System: prevents most disease; marked by the inflammatory immune response • Adaptive/acquired immune system: more advanced/specific; targets pathogens with specialized proteins (antibodies) Immune Enhancement • Nutrient-dense foods • Regular exercise • Whole food nutrition / herbal medicine Reduce Chronic Inflammation • Low-inflammation diet: – Minimize soy, refined foods, pasteurized dairy – Wild fish – 9 servings of raw vegetables (including cruciferous and carotenoid-rich) – Sufficient omega-3 fatty acids (97-99% of US population deficient in these) • Detoxify heavy metals (if high burden exists) Cruciferous (Brassica) Vegetables Eat plenty of these: broccoli, kale, brussels sprouts, cauliflower, arugula, chard, daikon, mustard greens, bok choy, cabbage, Chinese cabbage, radishes, watercress, collard greens, kohlrabi, rutabagas Synthetic “vitamins” increase cancer risk in smokers • • Results: Unexpectedly, we observed a higher incidence of lung cancer among the men who received beta carotene than among those who did not (change in incidence, 18 percent). Fewer cases of prostate cancer were diagnosed among those who received alphatocopherol than among those who did not. Beta carotene had little or no effect on the incidence of cancer other than lung cancer. Alphatocopherol had no apparent effect on total mortality, although more deaths from hemorrhagic stroke were observed among the men who received this supplement than among those who did not. Total mortality was 8 percent higher among the participants who received beta carotene than among those who did not, primarily because there were more deaths from lung cancer and ischemic heart disease. Conclusion: We found no reduction in the incidence of lung cancer among male smoker after 5-8 years of dietary supplementation with alphatocopherol or beta carotene. In fact, this trial raises the possibility that these supplements may actually have harmful as well as beneficial effects. – N Engl J Med. 1994 Apr 14;330(15):1029-35.

They knock them out so that the cells can’t communicate and can’t survive. It’s like they’re blinded. We think that’s what it is. No one knows. We know they work; the human and animal studies show they work even in aggressive laboratory models of cancer in mice, but we don’t know the mechanism.” – Nicholas Gonzalez, MD Enzyme Support Practitioners • John Beard, MD, England, 1902 • FL Morse, MD, St Louis, 1920s • William Kelley, DDS, 1960s – Author of “One Answer to Cancer” • Nicholas Gonzalez, MD, New York, 1987 The success of this approach has been well-documented and supported by lab findings and long-term clinical follow-ups.
