BPA exposure linked to brain tumors

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.

Researchers examined the relationship between BPA exposure and the diagnosis of meningioma. They followed 247 patients with the brain cancer and 258 patients with no history of cancer who were getting medical exams at the Union Hospital in Wuhan, China.
Meningioma was confirmed with a brain scan or a biopsy - a tissue sample. BPA concentrations were measured in participants' urine samples.
