30 year study finds no link between using mobile phones and brain cancer


A study carried out by the University of Sydney has found there is no link between the increase in usage of mobile phones and brain cancer.

Researchers carried out the study titled, Has the incidence of brain cancer risen in Australia since the introduction of mobile phones 29 years ago?, from 1982 to 2013 and found there was no statistical evidence to support claims that using mobile phones can lead to brain cancer.

According to the study published on Cancer Epidemiology, researchers examined the cases of 14,222 women and 19,858 men who had been diagnosed with brain cancer since 1982.

The study found that despite massive increases in mobile phone usage throughout the population in Australia, there was not a major increase in cases of brain cancer.

“With extremely high proportions of the population having used mobile phones across some 20-plus years (from about 9% in 1993 to about 90% today), we found that age-adjusted brain cancer incidence rates (in those aged 20-84 years, per 100,000 people) had risen only slightly in males but were stable over 30 years in females”, the study read.

However, the slight increase in cases that researcher found were only in the over 70 age group and started in 1982, which was before the introduction of the mobile phone in 1987. Researchers concluded that this increase in number of cases was likely to be due to improvements made in diagnosing the disease.

“The rise started before mobile phones were even available in Australia. It’s almost certainly attributable to the rise in Australia of more advanced diagnostic techniques,” said Simon Chapman, study lead and Emeritus Professor in Public Health at the University of Sydney.

Chapman said that the findings from the study come to the same conclusion as similar studies carried out in the US, UK and New Zealand.

“They are consistent in showing, over the time that mobile phones have been around – 29 years in Australia, there’s just been no increase in brain cancer in the population,” he added.

The possible health risks from long term use of mobile phones have long been debated.

In 2009, lawmakers in the United States wanted stickers to be added to handset warning of the potential risk from electromagnetic radiation on the brain when using a mobile phone. However, the plan was abandoned in 2013.

What are your thoughts on the findings of the study? Do you believe the increasing evidence that there is no link between long term mobile phone use and brain cancer?
