Exposure to bisphenol A may be a risk factor for a common type of brain tumor called meningioma, reports a study from China. This is the first study to suggest a link between brain cancer and the chemical, which is widely used in consumer products.
Those with the highest urine BPA levels were about 1.6 times more likely to be diagnosed with meningioma compared to those with lower concentrations.
This link was observed even after accounting for other factors associated with meningioma. More research is needed to confirm the findings.
