Cancer: Understanding and Overcoming This Complex Disease

Introduction to Cancer

Cancer is a group of diseases characterized by the uncontrolled growth and spread of abnormal cells in the body. These cells divide rapidly, forming tumors that can invade nearby tissues and metastasize to distant organs through the bloodstream or lymphatic system. Cancer can affect any part of the body, with over 200 types identified, including breast, lung, prostate, colorectal, and skin cancers. It is a leading cause of death worldwide, with approximately 10 million deaths annually, and about 1.9 million new cases diagnosed in the United States alone in 2022. Risk factors include genetics, environmental exposures (e.g., tobacco, UV radiation, carcinogens, tattoo ink), infections (e.g., HPV, hepatitis), and lifestyle factors like poor diet and physical inactivity.

Cancer is harmful because it disrupts normal organ function, leading to symptoms like pain, fatigue, weight loss, and organ failure. Metastatic cancer can spread to critical areas like the brain, liver, or lungs, significantly reducing survival rates (e.g., 5-year survival for metastatic lung cancer is ~7%). It also causes emotional distress, financial burden, and reduced quality of life. If untreated, cancer can lead to death, with certain types (e.g., pancreatic, liver) having particularly poor prognoses.

Understanding Cancer

The Generation of Abnormal Cells in the Body

The human body is in a constant state of cellular turnover, with trillions of cells dividing and replicating daily to maintain tissue health and function. During this process, errors can occur due to factors like DNA replication mistakes, exposure to environmental toxins, radiation, or oxidative stress, leading to the formation of abnormal cells. These cells may harbor genetic mutations or damage that could potentially make them precancerous if left unchecked. These damaged or mutated cells have the potential to evolve into cancer if protective mechanisms fail. This ongoing generation of abnormal cells is a normal part of biology, but the body has evolved sophisticated systems to detect and eliminate them before they pose a threat.

The Role of Autophagy in Cellular Cleanup

One key defense mechanism is autophagy, a cellular "self-eating" process where cells degrade and recycle their own damaged components, such as faulty proteins, organelles, or even entire mutated structures. This acts as an internal quality control system, preventing the accumulation of harmful materials that could lead to further mutations or uncontrolled growth. In the context of abnormal cells, autophagy helps suppress the early stages of cancer development by removing precancerous elements and maintaining cellular homeostasis. Enhancing autophagy through lifestyle factors like intermittent fasting or nutrient optimization can bolster this preventive function, reducing the risk of abnormal cells progressing.

Immune Surveillance and Elimination of Threats

Complementing autophagy, the immune system plays a crucial role in identifying and destroying abnormal cells through a process known as immune surveillance. Specialized cells, such as natural killer (NK) cells, cytotoxic T cells, and macrophages, constantly patrol the body, recognizing surface markers or antigens on damaged or mutated cells that signal them as "foreign" or aberrant. Once detected, these immune effectors trigger apoptosis (programmed cell death) or directly attack the cells, preventing their proliferation. This vigilant system ensures that most abnormal cells are eliminated before they can form tumors. Factors like a healthy diet, exercise, and even fasting can enhance immune function, such as by reprogramming NK cells for better efficacy against potential threats.

When Defenses Fail: The Onset of Cancer

Cancer arises when these protective mechanisms—autophagy and immune surveillance—are overwhelmed or impaired, allowing abnormal cells to evade detection, survive, and multiply uncontrollably. This failure can stem from genetic predispositions, chronic inflammation, aging, or lifestyle factors like poor nutrition or sedentary habits that weaken cellular repair and immune response. Once unchecked, these cells acquire additional mutations, forming a tumor that invades surrounding tissues, competes for nutrients and oxygen (effectively "hijacking" resources), and disrupts organ function. In advanced stages, they may metastasize to distant sites, leading to systemic issues. Understanding this process highlights the importance of supporting autophagy and immunity through natural means to prevent the transition from harmless abnormalities to malignant disease.

Our Pillars and Their Role in Preventing or Managing Cancer

Our three pillars—Nutrition, Exercise, and Intermittent Fasting—are known to prevent and support the management of cancer by reducing risk factors and enhancing the body’s resilience. These pillars lower incidence and improve outcomes. 

Intermittent Fasting (Known to Manage, Likely to Prevent)

Prolonged intermittent fasting (IF), reduces cancer risk by lowering insulin levels, reducing inflammation, and promoting autophagy (cellular cleanup), which inhibits cancer cell growth. In management, IF may play a roll in reducing the size of tumors. However, full blown extended fasting is showing promise in reducing cancers, and there have been many cases of stage 4 (terminal) patients who after 2 to 4 weeks of fasting have eliminated their tumors. Long term fasting is only possible in patients who have enough excess body fat to withstand long fasting periods. With careful care and supervision, consider long term fasting, otherwise resort to IF.

Nutrition (Known to Prevent, Supports Management)

A nutrient-dense, anti-inflammatory diet reduces cancer risk by 10-20% by combating oxidative stress and inflammation, which promote tumor growth. Antioxidants (e.g., Vitamins C, E, selenium) neutralize free radicals, while fiber or a carnivore diet lowers colorectal cancer risk by improving gut health. Cruciferous vegetables (e.g., broccoli) contain sulforaphane, which may inhibit cancer cell growth. Avoiding processed foods, alcohol, and other poor lifestyle choices prevents carcinogen exposure. During treatment, adequate protein and calories maintain muscle mass and support recovery, improving treatment tolerance.

Exercise (Known to Prevent, Supports Management)

Regular physical activity reduces cancer risk by 10-25% for cancers like breast, colon, and lung. Exercise lowers insulin resistance, inflammation, and obesity (a major risk factor), while boosting immune function to combat early cancer cells. For cancer patients, exercise improves fatigue, mental health, and treatment outcomes, with studies showing a 20-40% reduction in recurrence for breast and colorectal cancer survivors.

Nutrient Deficiencies Contributing to Cancer

While no single nutrient deficiency directly causes cancer, deficiencies can weaken the body’s defenses, increasing susceptibility. Key nutrients include:

• Folate: Low intake impairs DNA repair, increasing risks of colorectal and breast cancers.
• Iron: Deficiency may impair immune function, though excess iron can promote cancer growth.
• Magnesium: Deficiency may disrupt DNA repair and increase inflammation, potentially contributing to cancer risk.
• Omega-3 Fatty Acids: Reduce inflammation; low levels may elevate risks of breast and colorectal cancers.
• Selenium: Deficiency increases oxidative stress, linked to higher risks of lung, prostate, and colorectal cancers.
• Vitamin A: Supports cell differentiation; deficiency may increase risk of certain cancers (e.g., lung).
• Vitamin C: Antioxidant; deficiency promotes oxidative damage, potentially contributing to cancer development.
• Vitamin D: Low levels are linked to higher risks of breast, colorectal, and prostate cancers due to impaired immune regulation and cell growth control.
• Vitamin E: Protects cell membranes; low levels may increase cancer risk via oxidative stress.
• Zinc: Supports DNA repair and immune function; deficiency may increase cancer risk.

Medications That Drain Nutrients and May Contribute to Cancer

Medications for other disorders can deplete nutrients critical for cancer prevention, potentially increasing risk:

• Anticonvulsants (e.g., Valproate, Carbamazepine for epilepsy): Deplete folate, Vitamin D; impair DNA repair and bone health.
• Chemotherapy (e.g., Methotrexate): Depletes folate; disrupts DNA synthesis, potentially increasing secondary cancer risk (paradoxical).
• Corticosteroids (e.g., Prednisone for inflammation): Deplete Vitamin D, magnesium; weaken immune surveillance and bone health, linked to osteoporosis.
• Loop Diuretics (e.g., Furosemide for hypertension): Deplete magnesium, zinc; may impair immune and DNA repair functions.
• Metformin (for type 2 diabetes, insulin resistance): Depletes B12, folate; may impair DNA repair, increasing cancer risk.
• Oral Contraceptives: Deplete folate, B6, magnesium; may increase breast cancer risk.
• Proton Pump Inhibitors (e.g., Omeprazole): Deplete Vitamin B12, magnesium, iron; impair DNA repair and immune function.
• Statins (e.g., Atorvastatin for cholesterol): Deplete Vitamin D, CoQ10; may affect immune function.

Medications Known or Likely to Cause Cancer as a Side Effect

Certain medications increase cancer risk through DNA damage, immunosuppression, or hormonal changes:

• Androgens (e.g., Testosterone for hypogonadism): May increase prostate cancer risk in men.
• Aromatase Inhibitors (e.g., Anastrozole for breast cancer): May increase secondary cancers indirectly via bone loss (osteoporosis, paradoxical).
• Azathioprine (for autoimmune disorders): Increases lymphoma and skin cancer risk via immunosuppression.
• Estrogen/HRT (e.g., Estradiol for menopause, osteoporosis): Increases breast and endometrial cancer risk via hormonal stimulation.
• Cyclophosphamide (chemotherapy): Increases risk of bladder cancer and leukemia due to DNA damage (paradoxical).
• Immunosuppressants (e.g., Tacrolimus for organ transplants): Increase lymphoma and skin cancer risk.
• Oral Contraceptives: Increase breast and cervical cancer risk, though risk decreases after discontinuation.
• Phenobarbital (for epilepsy): Linked to liver cancer in long-term use.
• Proton Pump Inhibitors: May increase gastric cancer risk for long term use via chronic inflammation.
• Tamoxifen (for breast cancer): Increases endometrial cancer risk due to estrogen-like effects on the uterus (paradoxical).

Top Medications Prescribed for Cancer, Nutrient Depletions, and Other Disorders Caused

Cancer treatments vary by type and stage but focus on eliminating cancer cells or slowing growth, not curing the disease. Below are the top medications/procedures, their nutrient depletions, and associated disorders:

1. Doxorubicin (Adriamycin, chemotherapy): Depletes CoQ10, magnesium; causes cardiotoxicity, heart failure, thrombocytopenia, anemia.
2. Cyclophosphamide (chemotherapy): Depletes folate; causes bladder cancer, leukemia, thrombocytopenia, infertility.
3. Tamoxifen (hormone therapy for breast cancer): Minimal depletion; causes endometrial cancer, blood clots, hot flashes.
4. Paclitaxel (Taxol, chemotherapy): Depletes magnesium, Vitamin B12; causes neuropathy, thrombocytopenia, hair loss.
5. Cisplatin (chemotherapy): Depletes magnesium, zinc; causes kidney damage, hearing loss, neuropathy, thrombocytopenia.
6. Fluorouracil (5-FU, chemotherapy): Depletes folate; causes gastrointestinal toxicity, thrombocytopenia, mucositis.
7. Trastuzumab (Herceptin, targeted therapy): Minimal depletion; causes heart failure, infusion reactions.
8. Imatinib (Gleevec, targeted therapy): Minimal depletion; causes edema, liver toxicity, thrombocytopenia.
9. Bevacizumab (Avastin, anti-angiogenic): Minimal depletion; causes hypertension, bleeding, thrombosis.
10. Rituximab (Rituxan, immunotherapy): Minimal depletion; causes infections, thrombocytopenia, infusion reactions.

Why Our Pillars Prevent and Support Cancer Management, Unlike Medications That Treat Symptoms

Cancer medications like chemotherapy (e.g., doxorubicin, cisplatin) or hormone therapies (e.g., tamoxifen) target cancer cells or slow tumor growth but do not address root causes like oxidative stress, inflammation, or lifestyle factors. They carry significant risks (e.g., cyclophosphamide causing leukemia, tamoxifen causing endometrial cancer, cisplatin causing kidney damage) and focus on symptom control or tumor reduction rather than prevention or holistic recovery. Our pillars target underlying mechanisms: Nutrition reduces oxidative stress and inflammation with antioxidants and fiber, preventing cancer initiation; Exercise boosts immune surveillance and reduces obesity-related risks, lowering recurrence; IF may promote autophagy, potentially inhibiting early cancer cells. These approaches prevent cancer, enhance treatment tolerance, and improve long-term outcomes, unlike medications that manage disease progression without addressing its origins.
