Mobile phones, brain tumors and the Interphone study: where are we now?
In just 15 years the mobile phone has evolved from an uncommon, expensive, brick shaped object used in restricted areas of Western countries to a convenient and ubiquitous part of modern life, with more than 4.6 billion subscriptions worldwide (International Telecommunication Union 2010). The arrival of this mass technology has been accompanied by some public and media concern about the possibility that the radio frequency (RF) fields emitted by the phones might cause cancer, especially brain tumors.
