Risk of Breast Cancer? Do you know your Estrogen Metabolites?
Estrogen alone is not the issue when it comes to increasing the risk of breast cancer. The real issue is how is your estrogen being metabolized. You want to have your doctor order a test that evaluates the estrogen metabolites. **I recommend the Dutch Test (https://dutchtest.com) or the Rhein Hormone Test (http://www.rheinlabs.com)
The liver converts estrogens into estrogen metabolites. Three of estrogen’s metabolites, the breakdown products of this hormone, are 2-hydroxyestrone, 4-hydroxyestrone, and 16-alpha-hydroxyestrone.
Since the 1980s, 2-hydroxyestrone has been considered a “good” or chemoprotective form of estrogen, while 16-alpha-hydroxyestrone has been associated with the development of cancer. It can fuel the growth and division of hormone-dependent and other cancer cells more than the 2-hydroxyestrones can. The 2-hydroxyestrones, in contrast, have almost no estrogenic effect. Prevailing evidence has shown that the ratio of 2-hydroxyestrone to 16-alpha-hydroxyestrone is relevant as a risk factor for estrogen-sensitive cancers, including breast and cervical cancers. Simply put, when it comes to estrogen metabolites, you want more 2s than 16s. And guess what can help the body do that? Cruciferous vegetables.
