Does poor gut health increase breast cancer risk?

According to a new study published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism, women with diverse gut bacteria have a more favorable ratio of estrogen metabolites. These estrogen metabolites are associated with reduced risk for breast cancer. According to James Goedert, MD of the National Institutes of Health’s National Cancer Institute, women that had more different communities of gut bacteria had higher levels of estrogen fragments after the body metabolized the hormone, compared to women with less diversity intestinal bacteria.
More studies are needed on how gut health impacts breast cancer risk, but the findings from this particular study certainly indicate that indeed there is a relationship between a healthy gut and breast cancer. If you need more guidance on how to improve gut health or more diverse bacteria in the gut, please check back for my next blog post tomorrow. You can always schedule an appointment with my office as well.
