Abstract
The aim of the present meta-analysis was to identify whether there was a relationship between mobile phone use and risk of brain tumor. A comprehensive search strategy was developed, and studies were eliminated in a stepwise manner, based on the inclusion criteria. The current meta-analysis collected data from the 24 eligible studies to investigate the relationship between mobile phone use and risk of brain tumor, while a detailed analysis of different classification was also conducted in order to identify the risk of mobile phone use. From the results, the relationship between cell phone use and brain tumor incidence had no significant difference between men and women. Cell phone use can increase the RF energy absorbed in the brain and apoptosis genes expression level, but glioma cell line cells were not significantly affected. Most calculations of laterality show a trend of increasing risk for time since first use, cumulative duration of subscriptions, cumulative duration of calls, and cumulative number of calls. In Asian people’s, cell phone use and glioma had certain relations, while has very little relationship with meningioma incidence. This result seems to be no racial difference. In children and teenagers, cell phone use is associated with the incidence of brain tumors. We need longer time observation to supervise longer time (>20 years) mobile phone use whether has severe effects on incidence of brain tumor.
Highlights
With the rapid development of communication technology, mobile phones gradually began to rise from the mid - 1990s, and it is very popular in many countries
Research [9, 11] shows the relationship between cell phone use and brain tumor incidence had no significant difference between men and women
Further researches are need on the risk of brain tumors in children associated with use of mobile phones; future researches must accord with basic demands on quality, by which we mean efforts taken to ensure reliable assessment of results, and to obtain a sufficient number of cases and controls of which not just a few by modern measures have been exposed
Summary
With the rapid development of communication technology, mobile phones gradually began to rise from the mid - 1990s, and it is very popular in many countries. Due to the invention of the various APP, people were more and more inseparable from the mobile phones. Whether the using mobile phones harm human health had been received the widespread attention. Mobile phones made people exposed to highfrequency electromagnetic fields. In July 28th 2014, For all the diverse high-frequency exposures occurring in environmental and occupational settings ranging from long-waves [a type of amplitude modulation (AM) broadcasting with carrier frequencies between 153 and 280 kHz] to radar waves. Only a few long-term observational studies have been published (17.3). With the rapid development of nearly 10 years mobile phone usage, conclusions on this issue is changing.
