development of cancer in laboratory animals. In one study, mice genetically altered
to be predisposed to developing one type of cancer developed more than twice as
many such cancers when they were exposed to RF energy compared to controls.
There is much uncertainty among scientists about whether results obtained from
animal studies apply to the use of mobile phones. First, it is uncertain how to apply
the results obtained in rats and mice to humans. Second, many of the studies that
showed increased tumor development used animals that had already been treated
with cancer-causing chemicals, and other studies exposed the animals to the RF
virtually continuously--up to 22 hours per day.
For the past five years in the United States, the mobile phone industry has supported
research into the safety of mobile phones. This research has resulted in two findings
in particular that merit additional study:
In a hospital-based, case-control study, researchers looked for an association
between mobile phone use and either glioma (a type of brain cancer) or acoustic
neuroma (a benign tumor of the nerve sheath). No statistically significant association
was found between mobile phone use and acoustic neuroma. There was also no
association between mobile phone use and gliomas when all types of gliomas were
considered together. It should be noted that the average length of mobile phone
exposure in this study was less than three years.
