In October 2014, a Swedish research team published a medical journal "Pathopsysiology". The study resulted in a heightening concern for the increase of brain cancer by longtime users of mobile phones and wireless phones.
The study was conducted using two control trials. One included patients from 1997 to 2003 and the second included patients from 2007 to 2009. Almost 1500 Patients with malignant brain tumors were used along with 3530 controls.
The research indicated that people who use mobile phones for over 25 years are three times more likely to develop Glioma, a deadly brain cancer, compared to those who use these electronic devices less than a year.
The risk for developing brain cancer increased, by 30 percent, from the exposure to cell phone radiation. The risk appears to start low, but it increases over time. The risk of Glioma brain cancer increased significantly for every 100 hours of mobile phone use and per year of latency. The largest risk of Glioma seemed to be in the temporal lobe of the brain. The participants of the study who began using mobile phones at a younger age, and those before the age of 20, seemed to be at a higher risk for Glioma than all other age group participants.
The World Health Organization (WHO), announced in 2011, that it would reclassify radiofrequency electromagnetic fields emitted by wireless phones as a possible carcinogen. The Federal Communications Commission (FCC) also announced, early this year, that the will reassess the potential effects of radiation exposure from cell phones and mobile devices, as well. The FCC plans to look at the radiation exposure and determine how much is emitted by the devices and how those emissions affect humans, specifically, the human brain.
In the meantime, it is recommended that users of these devices try and reduce their risk of cancer by using headsets, speakerphones, holding the phone away from the body and text as often as possible.
