WARNING: Bisphenol A (used in can linings and plastic water bottles) exposure linked to brain tumor diagnosis.

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.

What does it mean?

Exposure to BPA may be a risk factor for the hormone-related brain cancer meningioma. The preliminary study found the higher the levels of BPA measured in urine samples, the higher the chance of a positive tumor diagnosis.

This is the first study to show a link between BPA exposure and diagnosis of meningioma.

Previous studies in animals have observed an association between BPA and other hormone-sensitive cancers like breast and prostate cancer. This study adds to that because, according to the authors, it "demonstrated emerging evidence of the role of environmental exposure to BPA on estrogen-sensitive tumors in humans."
