Endocrine disruptors are chemicals that interfere with our endocrine systems, which control the body’s hormones—such as insulin, testosterone, and estrogen—and numerous bodily functions ...
A comparison of the structures of the natural estrogen hormone estradiol (left) and one of the nonyl-phenols (right), a xenoestrogen endocrine disruptor. Endocrine disruptors, sometimes also referred to as hormonally active agents, [1] endocrine disrupting chemicals, [2] or endocrine disrupting compounds [3] are chemicals that can interfere with endocrine (or hormonal) systems. [4]
Xenoestrogens are a type of xenohormone that imitates estrogen.They can be either synthetic or natural chemical compounds.Synthetic xenoestrogens include some widely used industrial compounds, such as PCBs, BPA, and phthalates, which have estrogenic effects on a living organism even though they differ chemically from the estrogenic substances produced internally by the endocrine system of any ...
The concerns began with the hypothesis that BPA is an endocrine disruptor, i.e. it mimics endocrine hormones and thus has the unintended and possibly far-reaching effects on people in physical contact with the chemical. Since 2008, several governments have investigated its safety, which prompted some retailers to withdraw polycarbonate products.

There are 40 proton therapy centers in the U.S., said Dr. John J. Warner, CEO of the Wexner Medical Center and executive vice president at Ohio State. Cincinnati and Cleveland both have centers ...
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. [78]
DDT is an endocrine disruptor. [100] [101] It is considered likely to be a human carcinogen although the majority of studies suggest it is not directly genotoxic. [102] [103] [104] DDE acts as a weak androgen receptor antagonist, but not as an estrogen. [105] p,p '-DDT, DDT's main component, has little or no androgenic or estrogenic activity. [106]
