ABSTRACT
There has been a rapid increase in the use of both mobile phones and cordless phones during the last decade. The brain is the primary target organ during the use of the handheld phone. This has given concern of an increased risk for brain tumors, although other health effects are also discussed. Worldwide, an estimate of 6.8 billion mobile phone subscriptions was reported at the end of 2013 by the International Telecommunication Union (ITU; http:/ / www. itu. int/ en/ ITUD/ Statistics/ Documents/ facts/ ICTFactsFigures2013-e. pdf).
