October is breast cancer awareness month and is a great time to review the new research, which brings promising new breast cancer advancements in the fight against this devastating disease.
My best friend has been diagnosed with breast cancer – yet again. Since breast cancer is the second leading cause of cancer death and the most commonly diagnosed cancer among women worldwide, I am painfully aware my dear friend is far from alone. Standing by her side as she once again bravely fights this battle for her life has led me to research and gain new insights into what causes this horrible disease and where the keys to prevention lie.
Breast Cancer Advancement #1: It’s Your Environment, Not Your Genes That Determines Your Risk
In 1994, scientists discovered the BRCA1 gene and thought they had finally cracked the code on what causes breast cancer. But, subsequent studies showed that even though this gene may increase your risk of breast cancer, it isn’t the primary cause. Twin studies in Scandinavia showed that inherited genetics accounted for only 27 percent of breast cancer risk.
Then a study was done on Japanese descendants who migrated to the United States. Within one or two generations, these women’s rates of breast cancer increased to match the higher breast cancer rates of women in the US. These two studies together (and others like them) brought the truth to light – your environmental exposures play the most significant role in your breast cancer risk. Or, as genetic researchers like to say – genes may load the gun, but environment pulls the trigger.
There are many types of breast cancer, some hormone-sensitive and some not, and while they are different in their presentations, all of them share one thing in common – environmental triggers. These exposures can start as early as during development in the womb or as late as just before diagnosis, and are the hot topic for research right now. Environmental causes of breast cancer include:
- Urban air pollution
- Pesticides like DDT and glyphosate (RoundUp)
- Plastics like PCBs and BPA (NEVER microwave in plastic bags or containers!)
- X-ray and gamma radiation
- DES (a synthetic estrogen used to prevent miscarriages)
- Ethylene oxide (a sterilizing chemical)
- Smoking cigarettes
- Drinking alcohol
- Flame retardants in clothing, furniture, carpeting, and more
- Chemical solvents and dyes
- Mercury in seafood and dental amalgams
- Food additives
- Industrial chemicals used to make rubber
- Vinyl and polyurethane foams
- Byproducts and exhaust from burning fuels
- Too much artificial light at night
- Diet high in saturated and trans fats
- Triclosan in antimicrobial soaps and hand sanitizers
- Chemicals in sunscreens
- And so many more…
The diversity of breast cancer is challenging for researchers, because just as there are many different environmental causes, there are several types of breast cancer, some sensitive to certain hormones and some are not.
Breast Cancer Advancement #2: Hormone Replacement Therapy May Actually Reduce Risk
If you have modified your diet, take all the recommended supplements, and follow all the lifestyle recommendations I’ve outlined in Before the Change and still suffer with hormone imbalance, the good news is you can choose individualized bioidentical hormone replacement therapy to balance your hormones safely – and it doesn’t need to be discontinued after age 65.
Until 2017, we didn’t hear the whole truth on Hormone Replacement Therapy (HRT). Leaders like Holly Thacker, MD, who is a nationally known expert in womens health, criticized the unscientific interpretations of the Womens Health Initiative (WHI) and the conclusion that HRT is unsafe – from the time these conclusions were made. Unfortunately, her objections and those of her colleagues were initially blocked from publication 15 years ago. Thankfully, the tide has turned and the anti-hormone conclusions have recently been debunked.
Based on the input from Dr. Thacker and her colleagues, the North American Menopause Society reversed their decision and made a new statement about HRT in 2017. The scientific research shows they do not cause early death or increase cancer risk when used properly. They have determined that as with any hormone, whether it be thyroid, insulin, or sex hormones, hormones like HRT should be dosed based on the woman’s age, sex, stage in life, medical history, symptoms, test results, and her individual concerns. This means the dose is individualized, which is an important distinction to make when it comes to prescribing hormones, and one that was not accounted in the unscientific analysis of the WHI.
They even found balancing a woman’s hormones through HRT reduces her risk of breast cancer, colon cancer, and Type 2 Diabetes. In addition, family or personal history of breast cancer does not mean you can’t use HRT – though I would strongly suggest consulting a very knowledgeable health care professional before going this route. I also advocate using only bioidentical hormone replacement when it’s needed, and not the synthetic forms.
While all of this is promising, there is no magic pill – you need a healthy, anti-inflammatory diet and regular detox to keep your hormones balanced, even if you decide to use bioidentical replacements.
Breast Cancer Advancement #3: Eat Right for Your Hormones
It’s no secret obesity is a cancer risk. Your adipose tissue (aka fat cells) makes estrogen – it’s one way your body compensates as your ovaries start making less during perimenopause and menopause. This estrogen is metabolically active and when you have a lot of adipose tissue, you make a lot of estrogen and become estrogen dominant.
Estrogen dominance is a strong risk factor for breast cancer, as my good friend can attest. Her weight had crept up once again before the cancer returned. As you lose weight, your hormones come back into a better balance and your breast cancer risk decreases. And if you choose an anti-inflammatory diet to lose weight, recent studies show your risk of deadly postmenopausal breast cancer dramatically drops.
Over 60,000 postmenopausal women in the Netherlands were studied for more than 20 years for diet and other lifestyle factors. They looked specifically at the diets of over 2300 women who developed breast cancer, and found that postmenopausal estrogen receptor negative breast cancer was 40% lower when the following diet factors were present:
- Rich in vegetables and fruits of all types
- Includes whole grains
- Fats balanced and primarily from nuts, seeds, and their oils
- Regularly eats fish
- No processed meats (sausage, hot dogs, pepperoni, lunch meats, etc.) and very little red meat
- No legumes (beans, peas, etc.)
- No alcohol (includes red wine)
Spoiler alert: My new Radical Metabolism plan has all of these dietary components and more, to help you bring your health and your hormones back into optimal balance!
When you build healthy cells, they send the signals for balancing hormones of all types, from insulin to thyroid and sex hormones. If you are overweight and your energy is low, you very likely have a toxic metabolism and DNA damage to your cells. You need an anti-inflammatory approach to weight loss, hormone balancing, and detox, and it needs to start at the cellular level.
I know this all sounds like a daunting task, to get everything in your body back in balance when you feel fat and fatigued and your hormones are out-of-whack. This is why I created my new Radical Metabolism plan. It’s more than an anti-inflammatory, weight loss diet. It’s more than a seasonal and daily detox. It’s a lifestyle that takes you step-by-step through repairing your cells, reversing the DNA damage, detoxing your overworked organs, and creating an ideal environment – both in your body and in your home – to stay healthy and minimize your risk of all chronic diseases, including breast cancer.
