Can endocrine disruptors elevate risk of breast cancer?

August 15, 2017

"Hormone disruptors can affect how estrogen and other hormones act in the body, by blocking them or mimicking them, which throws off the body's hormonal balance." This imbalance may lead to the development of cancer later in life, Soto says, because "chemicals that affect mammary gland development may also increase the propensity to develop breast cancer." US News & World Report.
