Researchers see BPA effects in monkey mammary glands
Study adds to growing health concerns about common plastic additive
PULLMAN, Wash.—A new study finds that fetal exposure to the plastic additive bisphenol A, or BPA, alters mammary gland development in primates. The finding adds to the evidence that the chemical can be causing health problems in humans and bolsters concerns about it contributing to breast cancer.
“Previous studies in mice have demonstrated that low doses of BPA alter the developing mammary gland and that these subtle changes increase the risk of cancer in the adult,” says Patricia Hunt, a geneticist in Washington State University’s School of Molecular Biosciences. “Some have questioned the relevance of these findings in mice to humans. But finding the same thing in a primate model really hits uncomfortably close to home.”
