University graduates face higher brain tumour risk: study

People with at least three years of higher education are at greater risk for cancerous brain tumours than those with no more than nine years of schooling, perplexed researchers said Tuesday. "There is a 19 percent increased risk that university-educated men could be diagnosed with glioma," said Amal Khanolkar, a scientist at the Institute of Child Health in London and lead author of a study in the Journal of Epidemiology and Community. "It was a surprising result which is difficult to explain," Khanolkar told AFP.
