obesity increases risk of brain tumor

Study finds that obesity increases risk of developing brain tumor.


A study published in the journal Neurology has reported on a review of available clinical trials that have assessed the effect of overweight and physical activity on the risk of developing meningioma, a specific type of brain tumor.

The analysis of 18 clinical trials revealed that being overweight or obese increased the risk of developing meningioma, while being either overweight or obese did not have any effect on the risk of developing glioma. In addition, high levels of physical activity were inversely associated with meningioma.

The authors conclude that for meningioma, but not glioma, being overweight or obese increases your risk, while increased physical activity reduces your risk of developing this type of brain tumor.
