World Cancer Report 2014 published by the International Agency for Research on Cancer (IARC)
The World Cancer Report is book from the International Agency for Research on Cancer, the specialized cancer agency of the World Health Organization, and provides a unique global view of cancer, including cancer patterns, causes, and prevention.
The World Cancer Report series is recognized as an authoritative source of global perspective and information on cancer. The first volume appeared in 2003 and the second in 2008. This third volume in the series encompasses both established knowledge and recent research achievement.
Specifically on mobile phones and cancer:
“No consistent association has been found between use of mobile (cell) phones and brain tumours,” the report says
“Associations between heavy use of mobile phones and certain brain cancers have been observed, but causal interpretation is controversial; more data are needed, particularly on longer-term use of mobile phones.”
However, these possible links are not supported by evidence of an increase in the number of brain cancer cases during the rapid increase in mobile phone use globally.
Time trends in glioma incidence based on Nordic countries and the USA exclude any large increase in incidence attributable to mobile phone use, albeit with reference to a relatively short time from initiation of exposure. No association was observed between mobile phone use and other cancers.
Several studies on occupational exposure to radiofrequency electromagnetic fields provide no consistent associations.
Specifically on mobile phone networks, television and radio transmitters and cancer:
“With regard to environmental exposures from transmitters, including television, radio, and military transmissions as well as mobile phone networks, the evidence is inadequate due to lack of high-quality studies with accurate individual exposure assessment,” the report says
The report also says that research into mobile phones and cancer is continuing with major population studies on children and animal studies looking for a possible mechanism in progress.
“Prospective epidemiological studies – with accurate exposure assessment – still in progress now focus on possible effects of mobile phone use, also among youngsters,” the report says.
