Cell Phone Brain Tumor Link: Inconclusive

An international study into the link between cell phone use and two types of brain cancer has proved inconclusive, according to the World Health Organization’s International Agency for Research on Cancer. Results from the study are published this week in the International Journal of Epidemiology.

The 10-year study found that most cell phone use did not increase the risk of developing either meningioma or glioma. However, there were suggestions that heavy use of cell phones (more than 30 minutes per day) could increase the risk of glioma, but “biases and errors limit the strength of the conclusions that can be drawn from these analyses and prevent a causal interpretation.†

Despite the inconclusive results, the authors suggested further research was necessary.  A press release quotes Dr. Christopher Wild, director of the IARC saying:

An increased risk of brain cancer is not established from the data from Interphone. However, observations at the highest level of cumulative call time and the changing patterns of mobile phone use since the period studied by Interphone, particularly in young people, mean that further investigation of mobile phone use and brain cancer risk is merited.†

The IARC notes that mobile phone use has become much more prevalent today and it is not unusual for young people to use mobile phones for an hour or more a day. But this increasing use is tempered by the lower emissions, on average, from newer technology phones, and the increasing use of texting and hands-free operations that keep the phone away from the head.
