HER2-positive breast cancer is an aggressive form of breast cancer characterized by an overexpression of the HER2 protein, which promotes rapid tumor growth. Many individuals seek complementary and/or natural approaches to enhance their well-being, manage side effects, and support the body’s healing process.
Natural alternatives can play a crucial role in a holistic approach to cancer care. Below are some scientifically backed natural therapies that may help support the body alongside traditional treatments.
1. Anti-Inflammatory and Nutrient-Dense Diet
A well-balanced, nutrient-rich diet can help support the immune system and reduce inflammation, which is often linked to cancer progression.
Cruciferous Vegetables: Broccoli, Brussels sprouts, and kale contain sulforaphane, which has been studied for its potential anti-cancer properties.
Berries and Citrus Fruits: Rich in antioxidants and vitamin C, these help combat oxidative stress and boost immune function.
Omega-3 Fatty Acids: Found in flaxseeds, walnuts, and fatty fish, omega-3s may reduce inflammation and support cellular health.
Turmeric (Curcumin): This potent anti-inflammatory compound has shown promise in inhibiting cancer cell growth.
Garlic and Onions: These contain sulfur compounds that may help slow cancer progression and support detoxification.
2. Herbal Remedies and Supplements For HER2 Breast Cancer
Certain herbs and supplements have been researched for their potential to complement cancer treatment:
Curcumin: A compound in turmeric, curcumin has demonstrated anti-cancer properties by targeting cancer cell proliferation and inflammation.
Green Tea Extract (EGCG): This powerful antioxidant has been studied for its ability to slow the growth of HER2-positive cancer cells.
Medicinal Mushrooms: Reishi, turkey tail, and maitake mushrooms support immune function and have shown promise in cancer therapy.
Vitamin D: Low levels of vitamin D have been linked to a higher risk of breast cancer; supplementation may be beneficial under medical supervision.
Ashwagandha: An adaptogenic herb that may help reduce stress and support immune resilience.
3. Mind-Body Practices for Stress Reduction
Chronic stress can weaken the immune system and promote cancer progression. Mind-body therapies can help enhance emotional well-being and physical resilience.
Meditation and Mindfulness: Studies show that mindfulness meditation can reduce stress and improve quality of life for cancer patients.
Yoga and Tai Chi: Gentle movement practices improve flexibility, reduce fatigue, and promote relaxation.
Acupuncture: This traditional Chinese practice may help alleviate chemotherapy-related nausea, pain, and fatigue.
Breathwork and Guided Imagery: Techniques such as deep breathing and visualization can aid in stress reduction and healing.
Journaling and Emotional Expression: Writing down thoughts and emotions may help individuals process their experiences and reduce stress.
4. Detoxification and Gut Health
A strong digestive system supports immune health and enhances the body’s ability to eliminate toxins.
Probiotics and Fermented Foods: Yogurt, kefir, sauerkraut, and kimchi support gut health and immunity.
Fiber-Rich Foods: Whole grains, legumes, and vegetables promote detoxification through digestion.
Hydration: Drinking plenty of filtered water helps flush out toxins and supports cellular function.
Liver-Supporting Herbs: Dandelion root and burdock root can aid in natural detoxification processes.
5. Exercise and Lifestyle Changes
Regular physical activity is linked to better cancer outcomes and improved overall health.
Walking and Light Exercise: Moderate exercise, such as walking or stretching, can improve energy levels and reduce fatigue.
Strength Training: Helps maintain muscle mass, which is important during cancer treatment.
Adequate Sleep: Restorative sleep is essential for healing and immune function.
Avoiding Toxins: Reducing exposure to environmental toxins such as pesticides, processed foods, and endocrine disruptors (e.g., BPA) can support overall health.
Sunlight and Nature Exposure: Spending time in nature and getting adequate sunlight can improve mood and vitamin D levels.
If you have HER2-positive breast cancer, certain supplements and foods should be avoided as they may interfere with treatment, promote cancer growth, or increase inflammation. Always consult your oncologist or a registered dietitian before making dietary or supplement changes.
Supplements to Avoid
Some supplements can interact with chemotherapy, targeted therapies (like Herceptin), or hormone therapies:
Soy Isoflavones & Phytoestrogens (Soy Protein Isolate, Red Clover, Flaxseed Extracts, Dong Quai)
Contain estrogen-like compounds that may stimulate hormone-sensitive cancers, including some HER2-positive cases.
Milk Thistle
Increases Estrogen Levels and can accelerate tumor growth.
Omega-3 Fatty Acid Supplements (High doses)
May interact with blood-thinning medications. Getting omega-3s from food (like fish) is preferable.
Iron Supplements (unless prescribed)
Excess iron can promote oxidative stress and tumor growth. Only take if anemic and under medical guidance.
Serrapeptase
Can act as a blood thinner and create excessive bleeding if surgery is required.
HER2-positive breast cancer is not always hormone-sensitive, but some HER2+ cases are also ER+ (estrogen receptor-positive), meaning they respond to estrogen. If your cancer is HER2+ and ER+, avoiding estrogen-like compounds (phytoestrogens) may be beneficial.
What Are Estrogen-Like Compounds (Phytoestrogens)?
Phytoestrogens are plant-based compounds that mimic estrogen in the body. They can bind to estrogen receptors and may stimulate or block estrogen effects, depending on the situation.
Foods High in Phytoestrogens to Limit or Avoid
Flaxseeds & Flaxseed Oil
High in lignans, which act as weak estrogens. Whole flax in small amounts may be okay, but high doses of flaxseed extract should be avoided.
Legumes & Beans (contain phytoestrogens but in lower amounts)
Chickpeas, Lentils, Peas – Best consumed in moderation.
Red Clover & Herbal Supplements
Found in teas and supplements; high in isoflavones (estrogen-like).
Licorice Root & Dong Quai
Used in herbal medicine and teas; may act like estrogen.
Certain Seeds & Nuts (in high amounts)
Sesame Seeds, Sunflower Seeds, Almonds – Contain phytoestrogens, but moderate intake is generally safe.
Hidden Sources of Estrogen-Like Compounds
Plastic Containers – BPA (Bisphenol A) can leach into food and act like estrogen. Use glass or BPA-free containers.
Hormone-Treated Meats & Dairy – Opt for organic, hormone-free options when possible.
Personal Care Products – Some cosmetics and shampoos contain parabens, which mimic estrogen.
Can I Eat Any Phytoestrogens?
If your cancer is HER2+ but ER-negative, phytoestrogens may have less impact. However, if you’re HER2+ and ER+, it's best to be cautious, especially with soy supplements and highly processed soy foods.
Foods to Avoid or Limit
Processed & Red Meats (Bacon, Sausages, Deli Meats, Beef, Pork, Lamb)
Contain carcinogens (e.g., nitrites, heme iron) that can increase cancer risk and inflammation.
High-Sugar & Ultra-Processed Foods (Sodas, Candy, Cakes, White Bread, Fast Food)
Can contribute to insulin resistance, inflammation, and tumor growth.
Excessive Alcohol (Wine, Beer, Liquor)
Increases estrogen levels and cancer recurrence risk. Best to avoid or limit intake.
Soy-Based Processed Foods (Soy Protein Isolate, Tofu, Edamame, Miso, Tempeh in High Quantities)
Whole soy foods in small amounts are likely safe, but avoid highly processed soy products.
Fried & Trans Fat-Rich Foods (French Fries, Margarine, Packaged Snacks, Commercial Baked Goods)
Can promote inflammation and negatively impact overall health.
Dairy (Full-Fat Milk, Cheese, Butter in High Quantities)
Some studies suggest excess dairy may promote hormone-driven cancers, though research is mixed. Opt for organic, hormone-free dairy if consumed.
Grapefruit & Seville Oranges
Can interfere with drug metabolism (especially tamoxifen and some chemotherapy drugs).
What to Eat Instead?
Cruciferous Vegetables (Broccoli, Kale, Brussels Sprouts) – Contain cancer-fighting compounds.
Berries (Blueberries, Strawberries) – Rich in antioxidants without interfering with treatment.
Healthy Fats (Avocado, Nuts, Olive Oil) – Support overall health without excess inflammation.
Lean Proteins (Fish, Chicken, Lentils) – Helps maintain muscle mass.
Whole Grains (Quinoa, Brown Rice) – Better blood sugar control.
Green Leafy Vegetables (Spinach, Swiss Chard) – Provide essential nutrients.
Natural Alternative Protocols
A Natural & Repurposed drugs protocol needs to be individualized as each Cancer patient has their own individual requirements based on some of the following information:
The stage of the breast Cancer
Metasteses
Health of the individual’s main organs such as Heart (blood thinners, prior Heart ryhtym issues, Liver, Kidneys, Spleen, Pancreas, Lungs, Thyroid, Pituitary
Weight loss or maintaining
Current medications
Blood Chemistry results
These are things that must be asked of any Cancer patient, and failure to do so may place the Cancer patient in greater danger than the Cancer itself. I started this substack and my two facebook groups to bring light to the problems that I see in every group…Failure to ask the important questions to gain an understanding what each individuals needs are and to do no more hram to the person than what they are facing with their Cancer. I wrote my 588-page book to bring attention to the various Cancers, the use of Ivermectin, Fenbendazole, Mebendazole, Albendazole, CBD, THC and 17 other different proven Cancer killers. I have many blog articles here on my substack and on my website. I have an Ivermectin dose Calculator which I made in Excel to guide people in taking the appropriate doses of Ivermectin based on their weight and their individual needs whether that be parasitic elimintion or Cancer.
The dose calculator can be downloaded for free on my website: Brighter-works.ca
