An article published on February 11, 2014 on the web page of the broadcasting service Michigan Radio covers a recent study finding tumors in mice exposed prenatally to low doses of bisphenol A (BPA) (Weinhouse et al. 2014). The study published online on February 3, 2014 in the peer-reviewed scientific journal Environmental Health Perspectives (EHP) investigated the effects of BPA exposure on the liver. Animals were exposed to BPA during gestation and lactation. The researchers fed mice with doses of 0ng, 50ng, 50µg and 50 mg BPA per kg diet. Whereas previous studies detected only precancerous lesions in organ tissues following BPA exposure at statistically significant levels, Weinhouse and colleagues found hepatic tumors. They detected the tumors in mid-adulthood but, Dolinoy, senior researcher of the study, states in the article, more research is needed to understand the human relevance of these findings.
