12 Strategies to Prevent Breast Cancer
In western countries, 12% or 1 out of 8 women develops breast cancer. In 2016, an estimated 231,840 new cases of invasive breast cancer are expected to be diagnosed in women in the U.S., along with 60,290 new cases of non-invasive (in situ) breast cancer. Addressing key hormone levels and epigenetic immune system modifiers such as vitamin D3 and glutathione are critical for preventing or reversing breast cancer naturally. (23) Here are 12 natural strategies to prevent breast cancer.
Breast tissue is highly estrogenic and estrogen is a major growth phase hormone in the body. Your risk of breast cancer comes down to your genetic profile, your levels of immune system modifiers such as glutathione and vitamin D3 and your hormone ratios.
2 Classifications of Breast Cancer:
Contrary to popular belief, there are actually several different types of breast cancer. In order to properly diagnosis the cancer type, there are two main categories that must first be assessed: (13)
- Noninvasive (in situ) breast cancer: Cancer is specific to the breast and has not spread to surrounding tissue, lobes (glands) or ducts (tubes).
- Invasive breast cancer: Cancer metastasizes to other parts of the body through the blood stream and lymph nodes.
Breast Cancer Types
- Invasive Breast Cancer: Also known as infiltrating breast cancer, this type of breast cancer spreads to tissue around the breast or other regions of the body. IDC (invasive ductal carcinoma) makes up 70% of all invasive breast cancer types and begins in the milk ducts.
- Ductal Carcinoma: This cancer is of the most common cancer type and originals from the milk ducts which carry breast milk to the nipple. Ductal carcinoma in situ (DCIS) is known to involve the cancer promoter oncogene AC.
- Lobular Carcinoma: Lobes (glands that produce breast milk) are the original site of this cancer. This typically noninvasive form of breast cancer, lobular carcinoma in situ (LCIS), elevates the risk of developing invasive breast cancer in the future.
- Inflammatory Breast Cancer (IBC): IBC results in the blockage of lymph vessels in the skin of the breast from infected soft tissue. The description “inflammatory” is associated with the appearance of itchy, red, tender, warm and firm breast resulting from the accumulation of white blood cells and stimulated blood flow in the skin.
- Male Breast Cancer: This type of breast cancer develops from any cellular malignancy in breast tissue. Male breast cancer is most common in men between the ages of 60 and 70. A disorder known as gynecomastia in teenage boys can trigger concerns for cancer but is rarely caused by a tumor.
- Metastatic Breast Cancer: This cancer is characterized by the spread of cancer cells to other organs areas of the body. Common locations for the metastatic breast cancer are the chest wall, area where the best used to be, lymph nodes, bones, lungs, tissue around the lungs, liver and brain.
- Paget’s Disease of the Breast: A specific skin change on the nipple or areola may resemble eczema but is actually the evidence of this rare form of disease and breast cancer. This type of breast cancer results in 4.3% of breast cancers.
- Papillary Carcinoma: A rare breast cancer, papillary carcinoma is apparent by fern-like projections of cancer cells. This cancer is treated like invasive ductal carcinoma although the prognosis is better than other invasive types.
- Triple Negative Breast Cancer (TNBC): Usually invasive, this type of breast cancer accounts for 10 to 20% of all breast cancers and originates from the breast ducts. These types of cancer cells do not contain receptors for estrogen, progesterone or a protein called HER2 as do normal breast cells. On the other hand, 20 to 30% of breast cancer cancers are characterized by the over presence of HER2 receptors responsible for stimulating cell growth.
BRCA1 and BRCA2 Mutations
BRCA1 (BReast CAncer 1) and BRCA2 (BReast CAncer 2) are inherited gene mutations that are linked to an increased risk for the development of breast cancer. BRCA1 and 2 are both tumor suppressor genes, which means that they should function to prevent cell reproduction and proliferation. BRCA1 is on chromosome 17 while BRCA2 is located on chromosome 13. (14)
About 1 in every 400-800 people in our population carries an inherited mutation in BRCA1 or BRCA2 and roughly 5% of all breast and ovarian cancers are due to these mutations (25). Another 10% of breast cancer cases are in individuals with a family history of breast cancer but who do not carry the BRCA gene mutation.
The other 85% of breast cancer cases occur in women who did not have a previous family history of breast cancer. These are cases of epigenetic or environmental stressors such as toxicity and emotional stress that cause the breakdown and mutation in the genetic structure that leads to cancer cell proliferation.
BRCA and Breast Cancer Risk
Mutations in these genes increase the risk of developing breast cancer to 60-87% and the risk of developing ovarian cancer to 20-54% (5). A mutated BRCA gene can be inherited from either one of the parents. This is why it is called a hereditary mutation because it is from the direct germline. An acquired or somatic mutation comes through environmental stressors.
The BRCA1 gene plays a very important role in stopping the development of cancer. Women who have inherited a damaged version of this gene will have a higher risk of developing breast cancer. BRCA1 may also get altered through environmental stressors that “switch it off” in as many as 30 percent of tumors in patients who had a normal version of the gene.
The BRCA1 mutation is most commonly associated with triple negative breast cancer, which does not respond to hormonal treatments, cancer or radiation (15). These individuals will often have breast cancer appear about 2 decades earlier in the 25-45 age range. BRCA2 is associated primarily with post-menopausal breast cancer, although the risk of pre-menopausal breast cancer is significant. It is typically highly responsive to hormonal treatments. (16)
How BRCA Works
By nature the BRCA gene works to suppress cell reproduction and proliferation. Cancer cells are highly proliferative which means that they reproduce very quickly. BRCA produces proteins that are used by the cell in specific enzymatic pathways to repair DNA molecules that have double stranded breaks. BRCA1 also upregulates intracellular anti-oxidants such as glutathione, which helps protect the DNA from oxidative stress (8).
This process of precise DNA repair orchestrated by BRCA is extremely important to the integrity of our genome. If this process is not performed effectively than it leads to abnormal cell development and proliferation. The whole goal of BRCA1 is to ensure that DNA information has been accurately replicated and translated to the daughter cells. It is a key safeguard of the genome.
The body has the p53 gene (53BP1 in breast tissue) as a backup to the BRCA gene in order to regulate cell division and protect the genome. If the BRCA gene is unable to do its job effectively, 53BP1 would signal for the cell to go through a programmed death called apoptosis (26).
Certain types of mutations in the BRCA genes increase the activity of a protein degrading enzyme called cathepsin L (CTSL) which breaks down 53BP1 (27). This allows for the proliferation and survival of the BRCA mutated cell and the growth of an abnormal cell line.
Vitamin D and BRCA
Vitamin D has been known to regulate the epigenetic expression of thousands of genes. It helps to down-regulate inflammation and oxidative stress at the tissue, cell and genomic level and it may be the secret key to reducing cancer risk in individuals with BRCA mutations.
Susana Gonzalo Ph D and her research team published a powerful paper in the January, 2013 edition of The Journal of Cell Biology (28). Her team showed that vitamin D inhibits CTSL-mediated breakdown of 53BP1 in non-tumor cells. During this study, they found that treating the BRCA1 deficient tumor cells with vitamin D restored high levels of 53BP1.
This increased the genomic stability and reduced proliferation of abnormal cells. This study specifically found this issue in triple-negative breast cancers which are the most challenging cases because they don’t respond to conventional treatments.
Optimizing Vitamin D Levels
Individuals with BRCA1, BRCA2, a family or personal history of breast cancer should optimize their vitamin D3 levels. One can do this by getting high quality sun exposure that creates a light color change in their skin (pink, tan or darker) without burning. If you do this over 40% of your body weight, you have gotten 10-20,000 IU of vitamin D.
Getting vitamin D3 levels checked every 90 days is highly recommended and keeping the levels between 50-100 ng/ml is ideal. Individuals with chronic inflammatory diseases like cancer should aim to get their levels around 80-90 ng/ml. Regular sun exposure and supplementing with 5-10,000 IU of vitamin D3 daily (take supplement with fat based meal) will typically get the levels into this range. (21)
Glutathione and BRCA
BRCA1 and BRCA2 play a key role in controlling oxidative stress levels within the cell and in the DNA strands themselves. When these genes are mutated, they lose their ability to control oxidative stress within the genome. This leads to increased oxidative damage to the DNA and genomic instability.
Glutathione is the body’s master anti-oxidant and the most important anti-oxidant for protecting the DNA particles. Individuals with this gene mutation produce less glutathione endogeniously (within the body) but can increase exogenous (acquired) glutathione levels through natural lifestyle strategies. (20)
The most important factors include a nutrient rich diet full of vegetables, organic meat, herbs such as turmeric, onions and garlic along with fermented foods. Good sleep and stress management as well as regular exercise are especially key.
Additional supplementation with S-Acetyl Glutathione, Alpha Lipoic Acid, milk thistle, selenium and N-Acetyl Cysteine are also extremely helpful and highly recommended for someone with BRCA gene mutations or a history of cancer.
Estrogen Quotient Testing
Estrogen is an essential hormone for the function and well-being of the female and at a reduced level the male body. Estrogen can be broken down into 3 major subtypes. The ratios of these subtypes give us a lot of critical health information that correlate to the risk of someone developing a hormone sensitive cancer.
Estrogen is considered a growth and development hormone that is manufactured from cholesterol by a woman’s ovaries. It is also produced in lower concentrations in the fat cells and the adrenal glands in both males and females. The estrogen circulates in the blood and passes in and out of all the organs and tissues and is eventually metabolized by enzymes in the liver. (22)
Three Major Estrogens
- E1 or Estrone: This is the main form of estrogen produced during menopause. This is produced mainly in your liver and fat cells. Since toxins such as xenoestrogens, heavy metals, and other pollutants that directly affect hormone levels are stored in your liver and fat cells, individuals with higher levels of toxicity have altered and contaminated forms of estrone.
- E2 or Estradiol: This is the predominant estrogen produced during reproductive years and it is ten times more potent than E1 and about 80 times stronger than E3. Elevations in estradiol are linked to cancers of the breast, ovaries and uterus.
- E3 or Estriol: This is the protective form of estrogen that reduces cellular growth factors and other estrogens. Estriol reduces the more aggressive estradiol and protects against radiation induced cancer of the breast. We should normally have a ratio of 90% Estriol, 7% Estradiol and 3% Estrone in what is referred to as the Tri-Estrogen Formula. (17)
The Estrogen Quotient
The overall ratios of these hormones are titled your Estrogen Quotient or EQ. This formula was developed by estrogen researcher Dr Henry Lemon (29). He discovered that the greater the amount of cancer protective E3 is present in comparison to the growth promoting E1 and E2, the lower the risk of estrogen sensitive cancer development.
The EQ is found through the following formula:
Total E1+Total E2
If the EQ is below 1.0, the risk of Breast Cancer is higher than that of the individual whose EQ is above 1.0. The optimal ratio that is considered most protective to breast tissue is an EQ that is greater than 1.5. This quotient can also be useful to determine other aspects of hormonal health and risk of autoimmunity.
Estrogen Receptors and Tissue Growth
The estrogen receptor alpha (ER-alpha) is stimulated by both E1 and E2. ER-alpha receptor activation is considered to promote proliferative and pro-carcinogenic tissue changes. This receptor is found in the blood vessels, hypothalamus, ovaries, breast, liver, prostate, endometrium, lung and testes. (18)
The estrogen receptor beta (ER-beta) is stimulated by E2 and E3. The ER-beta receptor activation is considered to be anti-proliferative and anti-carcinogenic. This receptor is found in the blood vessels, kidney, prostate, breast, heart, skin, brain, intestines, endothelial cells, bone and lung. (19)
Estriol’s Cancer Protective Status
According to Dr Jonathon Wright MD, “Most conventional physicians and pharmaceutical researchers have long dismissed Estriol as a weak and unimportant estrogen. They have considered it to be primarily a metabolite of Estradiol and Estrone, which are far more potent in producing estrogenic effects.” (29)
Estriol acts much like many plant estrogens in that it benignly binds to ER-beta receptors throughout the body and especially where they are dense in the uterus and breast. Estriol and plant estrogens have a much weaker estrogenic effect than E1 and E2 and thus shield the tissues from the more potent estrogens.
It is hypothesized that many xenoestrogens, artificial estrogens, act more like the stronger estrogen molecule E2 and thus when they are not detoxified they end up leading to symptoms of estrogen dominance. European studies have demonstrated that higher Estriol counts in menopausal women are correlated with lower menopausal symptoms such as incontinence, vaginal drying, thinning hair and hot flashes.
The American Cancer Society summed up their look into new studies involving the risks and benefits of breast cancer screening with updated guidelines in October of 2015. New recommendations follow for women with an average risk: (1)
- Most women should receive yearly mammograms starting at age 45.
- Women should speak with their medical provider if they choose to begin screening at age 40.
- Women should have mammograms every other year starting at age 55.
- So long as a woman is in good health she should receive regular screenings.
- Both breast exams by a doctor and self-exams are not recommended.
These recommendations contradict the American College of Obstetricians and Gynecologists guidelines which maintains that women should receive a clinical breast exam and regular screenings starting at age 40.
Experts analyzing the efficacy of early breast cancer detection learned that women between the ages of 40 to 69 whom received regular mammograms reduced the number of breast cancer deaths (2). Dr. Richard Wender with the American Cancer Society stated that a “woman should make a personal decision as whether she should start screening before age 45 but we clearly recommend that by age 45 all women should start regular screening every year (3).”
So what is the right choice for you to make and should mammograms be the recommended strategy to early detection screening?
The absence of pain in a breast lump is not a sign of the absence of breast cancer as up to 98% of women in some countries may believe. Completing monthly self-breast examinations can help reduce mortality rates associated with breast cancer by increasing the likelihood that a woman will receive attention from a healthcare practitioner immediately. In fact, awareness for “early cancer lump is painless” as it is coined is an effective strategy for women in low and middle income countries to decrease breast cancer mortality. (4)
Keeping cost effective breast cancer screenings on the public health agenda in countries like the U.S. may seem worth its benefits to you. Conducting breast self-examinations continues to raise awareness of a disease that is the most common cancer in the world amongst women (6).
Risk of Mammography
The high cost and funding for mammograms may be partially to blame for the general public’s assumptions that mammography testing is essential to detecting breast cancer. Unfortunately, there are several risks and dangers involved in mammography use that you should be aware of.
- Radiation Exposure: Patients are exposed to ionizing radiation to produce an X-ray image of breasts (9). For instance, cancer promoters such as oncogene AC prevalent in DCIS becomes stimulated from exposure to radiation during mammograms increasing risk of developing breast cancer.
- False Positives: Doctors in both the medical and natural health communities are skeptical of the high percentage of false positives detected during screening. False positives lead to further unnecessary, invasive and dangerous testing that results in no presence of tumors in 70-80% of cases (12).
- Financial Burden & Stress: Patients undergo a considerable amount of pain and stress involved in receiving mammograms. Both the screening and treatment cost is enough to burden any individual and family promoting greater emotional and physical stress.
Benefits of Thermography
Thermography testing is a new diagnostic tool designed to detect physiological abnormalities present in the body. A digital map is produced using heat patterns that identify inflammatory pathways associated with infection and cancer. This type of screening can be used well before the presence of a large mass is detectable on a mammogram by providing detailed information on vascular function. Mammograms only detect anatomical changes. (7)
Thermography screening works by providing a relatively accurate image of blood flow and temperature of areas in the body. Areas that present a state of thermal asymmetry may indicate cancerous development. Cancer cells rely on a steady supply of blood flow and nutrients resulting in the image of increased thermal heat to the infected area.
So reliant are the results of thermography that this screening can detect cancer cell growth an estimated 10 years prior to the identification of tumor by a mammogram. Thermography screening was found in a large and longer term study over 30 years and consisting of 250,000 women to be 90% accurate (10, 11).
Unlike mammograms, thermograms are more cost effective, painless, non-invasive, reliable and safe.
12 Ways to Prevent Breast Cancer
Here are the best action steps to get started with on your journey to prevent and/or beat breast cancer naturally. You should always consult with your physician before stopping or changing medications or taking on new health strategies.
Additionally, you should be working with a functional health practitioner to help guide you through these strategies. This is not an exhaustive list and there are other natural therapeutic strategies that I and functional health practitioners will utilize to help individuals with breast cancer.
1) Anti-Inflammatory Diet: Following a nutrition plan that is low in sugar and carbohydrates and rich in anti-oxidants, healthy fats and clean, organic protein is extremely important. Be sure to avoid commercial raised meats, trans fats and high sugar foods. Load up on healthy fat sources like coconut products, avocados, grass-fed butter and olives and olive oil. Get a lot of vegetables, herbs and low sugar fruits like berries in your diet. Look for organic and grass-fed/pasture-raised animal products.
2) Optimize Your Vitamin D: Low vitamin D3 is associated with poor cellular growth control and increased risk of breast cancer. Be sure to increase your vitamin D through good amounts of regular sun exposure and/or taking a high quality vitamin D3/K2 supplement.
2) Good Sleep: It is absolutely critical to sleep well in order to produce healthy sex hormones. Inadequate sleep will result in elevated stress hormone production and estrogen imbalance. It also causes blood sugar imbalances and abnormal breast growth. Follow these strategies to improve your sleep quality.
4) Increase Anti-Oxidant Consumption: Drink anti-oxidant rich teas such as passionflower, chamomile and decaf green tea for an extra dose of anti-oxidants and phytochemicals to assist the body in the detoxification cycles necessary for healthy estrogen levels.
5) Use Natural Products: Be sure to avoid all plastics, deodorants, shampoos, household cleaning agents and anything else with xenoestrogen substances. This article has a list of things to avoid.
6) Use a High Quality Omega 3 Supplement: I have all of my prostate clients using 2-5 grams of omega 3 fatty acids. This helps to reduce inflammation in the breast and estrogen dominance. Research has revealed that high dose omega 3 fatty acids are very effective at balancing estrogen levels. I also recommend 200 -500 mg of GLA with the omega 3’s for added anti-inflammatory benefits.
7) Zinc and Magnesium: Be sure to optimize your zinc and magnesium levels. Both of these nutrients are key for estrogen balance and xenoestrogen detoxification. Pumpkin seeds are one of the richest sources of both zinc and magnesium. Additionally, make green drinks or use super green powders and consume healthy organic meat products.
8) Practice Deep Breathing: Deep breathing can help calm an overactive sympathetic (fight or flight) nervous system and relax the body. This lowers stress hormone and reduces inflammation and abnormal growth in the body. Check this article out for more info on deep breathing.
9) Low Intensity Movement: A sedentary lifestyle is detrimental for estrogen balance and promotes overall estrogen dominance. Throughout the day, get a lot of low-intensity movement such as walking, light cycling, playing, etc. Regular movement will help reduce inflammation in the body and improve estrogen balance and breast health.
10) Intermittent Fasting: Going 16 hours between dinner and breakfast is one of the best ways to cleanse the body and reduce whole body inflammation and cancer growth. Consume your meals in an 8 hour window such as 11am – 7pm. Read this article for more info on fasting.
11) Use Cancer Stem Cell Killing Agents: There are many natural agents that prevent the growth of cancer stem cells. Using things like green tea extract, curcumin, glycosinolates, DIM, lycopene, resveratrol, quercetin and many others will help to induce cancer stem cell apoptosis and help to improve the bodies natural immune response.
12) Improve Your Lymphatic System: The lymphatic system is like the drains in your home. When your toilet dosn’t flush, particles become stagnant in the drain and the substances in the toilet begin to rot and decay. Just like your pipes, the lymphatic system can become congested and lead to adverse health reactions including soreness of breast, fatigue, eczema and chronic skin problems, cold limbs, bloating, headaches, body rigidity, and weakened immunity. Follow the strategies in this article to improve your lymphatic system.
