Xenoestrogen
Xenoestrogens are clinically significant because they can mimic the effects of endogenous estrogen and thus have been implicated in precocious puberty and other disorders of the reproductive system.
Risk factors for breast cancer
Many xenoestrogens (industrially made estrogenic compounds) are endocrine disruptors, and potential risk factors of breast cancer.
Endocrine disruption is the hypothesis that some chemicals in the body, such as Bisphenol A, are capable of interfering with the production, processing, and transmission of hormones.
