The correlation between smartphone usage and brain cancer is one which has baffled researchers for decades but a new study now shows that concerns were likely blown out of proportion. According to a study from the University of Sydney and the University of New South Wales, any correlation found between the usage of mobile phones and brain cancer isn’t found.
In Australia, where the number of mobile phone users has increased from just around 9 percent in 1993 to around 90 percent today, mobile phones have blown to fairly large proportions. The rise of mobile phones hasn’t been matched by an equal rise in chances of getting brain cancer among people on whom the research was conducted, however.
Among the group of people being looked at, from the stats available from the last three decades, the likelihood of getting the disease only increased significantly among the aged, people more than 70 years old.
Among males, the incidences of the disease increased only slightly while among the females it was fairly stable over 30 years.
For the correlation to exist, the total number of cases to have existed in the data would be 1,866. Instead, there were only 1,435 cases, markedly lower than being justified by the rise in phones around. The research assumes a 10-year lag between the usage of mobile phones and the increase in likelihood of getting cancer.
A fairly large number, 34000, who were diagnosed with brain cancer between 1982 and 2012, and national phone usage data between 1987 and 2012 was used in the study.
This study doesn’t mean you should go out of your way and start using your phones even more, but at least we now have data on your hands to dispel the myth which has circulated for decades.
