Mobile phones do not increase cancer risk study reveals

Mobile phones do not increase the risk of cancer, according to the findings of a Danish study published this week. 

Scientists from the Institute of Cancer Epidemiology in Copenhagen conducted a large study involving more than 350,000 people.

They looked people aged at least 30 who subscribed to mobile phone contracts and compared their rates of brain tumours with non-subscribers between 1990 and 2007.

Outside experts said the large scale of the trial was impressive, and that a series of other studies have reached similar conclusions.

"This paper supports most other reports which do not find any detrimental effects of phone use under normal exposures," said Malcolm Sperrin, director of Medical Physics at Britain's Royal Berkshire Hospital and Fellow of the Institute of Physics and Engineering in Medicine.

The World Health Organisation's International Agency for Research on Cancer decided in May that cellphone use should be classified as "possibly carcinogenic to humans", putting then in the same category as lead, chloroform and coffee.

However the International Commission on Non-Ionizing Radiation Protection's committee on epidemiology said just a month later that the scientific evidence increasingly pointed away from a link between mobile phone use and brain tumours.

The number of mobile phones has risen hugely since the early 1980s, with nearly 5 billion handsets in use today, prompting lengthy debate about their potential link to the main types of brain tumour, glioma and meningioma.

The results of the Danish study have been released on the British Medical Journal's website.
