Chinese researchers published a one year case-study where they measured the levels of BPA in urine of hundreds of patients. After analyzing the data, the researchers found a positive association between higher concentrations of BPA and the occurrence of meningioma, a common brain tumor. The positive association held even after accounting for other meningioma risk factors. Estrogen is known as a risk factor for the development of meningioma and this study supports the idea of synthetic estrogen-like chemicals such as BPA being involved in the cases where tumors are diagnosed. Although there were several limitations to the study, the researchers suggested that clinicians and patients should be aware of the risk of those products that contain BPA.
