Is Estrogen Dominance Linked to Breast Cancer?


At one point in my life I had a lot of symptoms that seemed unrelated at the time: extremely painful periods, heavy clotting and even vomiting and insomnia. As time went on, I also had to deal with fibrocystic breasts and ovaries. You may know what came next: Breast Cancer.

After diving into research and connecting the dots, I realized that estrogen dominance was one of the root causes of my developing Breast Cancer. 

Xeno-estrogens Contribute to Estrogen Dominance

Despite what some doctors may tell you, your hormones are not your enemy. Xeno-estrogens, however, most definitely are!

Xeno-estrogens are chemical toxins found in commercially produced food and body care products, pesticides, tap water, and in a multitude of other environmental toxins. BPA, or Bisphenol A, found in plastic water bottles and tin cans is probably the most well-known synthetic estrogen that can mimic estrogen in the body. 

If one has a problem breaking down estrogen and foreign chemicals because of poor  methylation pathways or a sluggish liver, these estrogens can build up in the body and in the blood stream.  This can be a contributing factor to estrogen dominance. 

Reduce your toxic exposure to chemical estrogens since they

can increase your risk for Breast Cancer. 

And this, coupled with lower levels of progesterone as we age, can also set the stage for cancer development.  

Top Symptoms of Estrogen Dominance

Here are some signs that you may be suffering from estrogen dominance (or high levels of estrogens):

-Heavy, painful periods

-Large clots during your period

-Emotional issues (i.e. depression, anxiety, mood swings, irritability and PMS-like symptoms)

-Uterine fibroids

Estrogen Dominance and Breast Cancer

The most severe consequence of long-term estrogen dominance is cancer. For women, this can come in the form of uterine, ovarian, thyroid, lung or Breast Cancer.

There are dozens of studies which connect xeno-estrogens and estrogen dominance  to the development of Breast Cancer. One ground-breaking study was conducted in 2010 by the Fox Chase Cancer Center in Philadelphia. The researchers at Fox Chase created both laboratory and live models which demonstrated the carcinogenic effects of an overabundance of aggressive forms of estrogen and BPA on breast tissue.

What You Can Do to Prevent or Reverse Estrogen Dominance

In my quest to balance my hormones and heal my body,  I completed a saliva test that measured the levels of the three forms of estrogen: estradiol (E2, the most aggressive form), Estrone (E1) and estriol (E3, the mildest form). Talk to your health professional about getting this test done. The EQ Ratio, or estrogen quotient ratio, should be above 1. 

This formula was developed by Dr. Henry Lemon, a hormone researcher who discovered that the higher the Estriol in relationship to the other 2 estrogens, the lower the Breast Cancer Risk.

An important aspect of reducing your estrogen load is to include plenty of cancer-busting and hormone-balancing substances in your diet such as  organic cruciferous and leafy green vegetables, turmeric, matcha green tea and flax seeds.

The side effects of estrogen dominance can make your life very challenging.. I know because I experienced it for years. What I also know is that with time, patience and lifestyle changes, you can be free of estrogen dominance forever!

  • Finding this information so helpful! Didn’t know about the saliva test to measure different types of estrogen but my doc does bloodwork for this. Seems less invasive to test the saliva. Would be an interesting comparison too. Now I can go back to my doc (also a natural – path) and talk about this. So appreciate your research !
