Question: can excessive drinking cause a brain tumor?
Answer: The RRs for drinkers versus non-drinkers were 0.93 (95% CI 0.81-1.07) for glioma and 0.71 (95% CI 0.45-1.12) for meningioma. Conclusions: Alcohol drinking does not appear to be associated with adult brain cancer, though a potential effect of high doses deserves further study.
