INTERPHONE, a 13-nation study, is the biggest study undertaken of its kind into potential health impacts of mobile phones. It was co-ordinated by the International Agency for Research on Cancer (IARC), which is part of the World Health Organization (WHO), and adds to the large body of existing research into health effects of radiofrequency emissions.

Dr Christopher Wild, Director of the International Agency for Research on Cancer (IARC) in announcing the INTERPHONE results said:

“An increased risk of brain cancer is not established from the data from interphone. However, observations at the highest level of cumulative mobile phone use since the period studied by interphone, particularly in young people, mean that further investigation of mobile phone use and brain cancer risk is merited.”
