July 28, 2011 Children and adolescents who use mobile phones are
not at a statistically significant increased risk of brain
cancer compared to their peers who do not use mobile phones,
according to a study published July 27 in the Journal of The
National Cancer Institute. Mobile phone usage has increased
among children and adolescents in recent years. The increased
usage has raised a concern about the possibility of the
development of brain tumors in this population since children
have a developing nervous system; also, because their head
circumference is smaller, the radio frequency electromagnetic
fields may penetrate regions that are deeper in their brains.
However, no previous study has examined whether mobile phone
usage among children and adolescents is associated with a
difference in brain tumor risk. To determine the relationship
between mobile phone usage and brain tumor risk among children
and adolescents, Martin Röösli, Ph.D, of the Swiss Tropical and
Public Health Institute in Basel, Switzerland,
