Inflammatory breast cancer (IBC) is the most difficult type of breast cancer to cure in part due to its ability to quickly develop resistance to cancer treatment drugs. Bisphenol-A (BPA) is a nearly ubiquitous chemical substance used in plastic food and drink containers and in epoxy resins (such as those used to seal food cans). In this study, IBC cells were treated with low levels of BPA, as well as five other endocrine-disrupting chemicals. The results were especially alarming for those diagnosed with IBC. The findings indicate that BPA can play a role in inhibiting the effectiveness of some drugs used to treat IBC.
