Unfortunately, that study is virtually meaningless, at least as reported.

It studied 500 people who all had brain cancer and found that the 250 that had meningioma tended to have higher levels of BPA in their urine. While this implies that BPA causes meningioma, one could just as validly deduce that meningioma causes higher levels of BPA or that meningioma causes one to consume more canned food.

Apparently, meningioma is most often benign and asymptomatic, so if BPA makes one more likely to that type of cancer instead of another, perhaps we should eat more canned food!
