Danish study finds no health risk for long-term mobile phone users

The biggest and longest-running study on the issue has found that long-term mobile phone use does not raise the risk of cancer.

A Danish study followed 420,000 mobile phone users for up to 21 years and found that long-term mobile phone users did not have a higher risk of brain or central nervous system cancers, salivary gland tumours, eye tumours or leukaemia.

The study, which appears in the Journal of the National Cancer Institute, is the first to include people who have used a mobile phone for as long as 21 years.

The study matched Denmark’s mobile phone records against the Danish Cancer Registry. It followed people who started using mobile phones between 1982 and 1995 and checked them for a range of cancers in 2002. About 52,000 of the participants in the study had been using their mobile phones for 10 years or more and the study found their cancer rate was no higher than that of the general population.

“We found no evidence for an association between tumour risk and cellular telephone use among either short-term or long-term users,” said Christoffer Johansen of the Danish Institute of Cancer Epidemiology, who led the research.

“Moreover, the narrow confidence intervals provide evidence that any large association of risk of cancer and cellular telephone use can be excluded.”

The Chief Executive Officer of the Australian Mobile Telecommunications Association (AMTA), Chris Althaus, said the Danish study offered reassurance to long-term users of mobile phones.

“This study confirms the large body of research into the health effects of radiofrequency emissions. Comprehensive reviews of more than 1400 research publications, including 350 studies specifically on mobile phones, by governments and health authorities continue, without exception, to find there is no substantiated scientific evidence of health effects,” he said.
