How does this energy affect the cells over time?
Does this constant exposure disrupt cellular processes, especially when held up to the brain?
While the NCI says that a cell phone's non-ionizing radiation has not been proven for carcinogenic activity, other studies may prove otherwise.
This study coincides with a report in 2011 from the International Agency for Research on Cancer showing how mobile phones let off radio frequency fields that are capable of possessing carcinogenic activity in some people.
In this new French study, glioma and meningioma brain tumors occurred three times more often than normal in patients who used their cell phones extensively in their careers and day-to-day activities.
"Our study is part of that trend, but the results have to be confirmed," said Isabelle Baldi, of the University of Bordeaux in southwestern France, who took part in the study.
Naysayers of the study believe that the results cannot be confirmed and do not include an accurate picture of phone use in real life, including factors such as smoking. Furthermore, a relationship between cell phone use and cancer is never established in the cohort study. Also, as phone technology evolves, different levels of radioactivity are emitted by different phones, making cancer connections nearly impossible to make.
The study even acknowledged this: "The rapid evolution of technology has led to a considerable increase in the use of mobile phones and a parallel decrease of [radiowave intensity] emitted by the phones."
"It is difficult to define a level of risk, if any, especially as mobile phone technology is constantly evolving."
On average, glioma and meningioma patients used their cell phones more extensively for career and lifestyle purposes. Those in sales used their phone the most, which likely contributed to the higher prevalence of brain cancer.
