Don't hang up-cellphones don't cause brain tumours (probably)

摘要

Do Cellphones cause brain tumours? The World Health Organization hoped a $30 million study, involving 50 scientists in 13 countries, would provide an answer. Its "Interphone" study reported its final results this week and, sadly, we remain none the wiser, "An increased risk of brain cancer is not established, but it's important to note that we can't establish absence of risk either," says study leader Elisabeth Cardis of the Centre for Research in Environmental Epidemiology in Barcelona, Spain.
