Endocrine disruptor include DDT, polychlorinated biphenyls (PCB's), bisphenol A (BPA), polybrominated diphenyl ethers (PBDE's), and a variety of phthalates. In fact, almost all plastic products, including those advertised as "BPA free", have been found to leach endocrine-disrupting chemicals. In a 2011, study it was found that some "BPA-free" products released more endocrine active chemicals than the BPA-containing products. Other forms of endocrine disruptors are phytoestrogens (plant hormones). Xenoestrogens are a type of xenohormone that imitates estrogen. Synthetic xenoestrogens include widely used industrial compounds, such as PCBs, BPA and phthalates, which have estrogenic effects on a living organism. Alkylphenols are xenoestrogens. The European
Multiple endocrine neoplasia type 2b Multiple endocrine neoplasia type 2b Multiple endocrine neoplasia type 2B (also known as "MEN2B", "Mucosal neuromata with endocrine tumors", "Multiple endocrine neoplasia type 3", and "Wagenmann–Froboese syndrome") is a genetic disease that causes multiple tumors on the mouth, eyes, and endocrine glands. It is the most severe type of multiple endocrine neoplasia, differentiated by the presence of benign oral and submucosal tumors in addition to endocrine malignancies. It was first described by Wagenmann in 1922, and was first recognized as a syndrome in 1965-1966 by E.D. Williams and D.J. Pollock. MEN 2B typically manifests before a child is 10 years
