International Studies On Cell Phone Use

International studies on cell phone use


International studies show a connection between cell phone use & malignant gliomas & acoustic neuromas in cell phone users.


In 2007, Dr. Lennart Hardell, from Örebro University in Sweden, reviewed published epidemiological papers (2 cohort studies and 16 case-control studies) and found that:


  • Cell phone users had an increased risk of malignant gliomas.
  • Link between cell phone use and a higher rate of acoustic neuromas.
  • Tumours are more likely to occur on the side of the head that the cell handset is used.
  • One hour of cell phone use per day significantly increases tumour risk after ten years or more.


A Swedish scientific team at the Karolinska Institute conducted an epidemiological study (2004) that suggested that regular use of a mobile phone over a decade or more was associated with an increased risk of acoustic neuroma, a type of benign brain tumor. The increase was not noted in those who had used phones for fewer than 10 years.


The 13 nation INTERPHONE project – the largest study of its kind ever undertaken – was published in 2011 and found a doubling of tumour rates among the highest users of mobile phones. High users were defined as those using the phone for an average of half an hour per day.
