Breast Cancer and The Estrogen Connection
Many of today’s female cancers
—breast in particular—are estrogen dependent. If your body has too much estrogen
, the normally supportive hormone can become toxic, leading to cancer.
Most medical professionals refer to excess estrogen as estrogen dominance. To thoroughly understand why estrogen dominance is a major risk factor for female cancers, let’s take a quick look at the way estrogen is metabolized in your body.
Though we speak of estrogen in general, your body actually produces three types of estrogen: estradiol (the most potent), estrone, and estriol.
During estrogen metabolism, estradial is converted into estrone. Estrone then becomes either 2-hydroxyestrone—a “good” estrone metabolite—or 16-alpha-hydroxyestrone—a “bad” estrogen metabolite. The good metabolite (2-hydroxyestrone) is then converted into 2-methoxyestrone and 2-methoxyestrodial.
