The past two decades have witnessed a dramatic increase in the number of child cell phone users in developed countries where statics suggest that a majority of youngsters start to use mobile phones by the of age nine or 10.

Young brains possessing a developing nervous system may be more susceptible to serious health effects, including cancer through cell phones, as the device emissions tends to penetrate deeper into their brains. Various studies have suggested that that the outer brain tissue of children aged from 5 to 8 may absorb twice the amount of cell phone energy as absorbed by adult brains.

However, a recent study has denied the facts and claimed no association between cellular-phone use and brain tumors in children and adolescents. The study, on around 1, 000 participants, was stimulated through concerns that young brains are particularly sensitive to phone emissions.

The lead study researcher, Denis Aydin, from the Swiss Tropical and Public Health Institute, in collaboration with colleagues has examined the data on various parameters, as an attempt to understand negative effects of cell phone among long term users.

"Scientific evidence has overwhelmingly indicated that wireless devices do not pose a public health risk for adults or children”, added John Walls of CTIA-The Wireless Association, in a statement.
