Briefly, there is not enough evidence to know for sure, either way; 

however, research efforts are on-going. The existing scientific 

evidence is conflicting and many of the studies that have been done 

to date have suffered from flaws in their research methods. Animal 

experiments investigating the effects of RF exposures characteristic 

of mobile phones have yielded conflicting results. A few animal 

studies, however, have suggested that low levels of RF could 

accelerate the 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 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. 

When 20 types of glioma were considered separately, however, an 

association was found between mobile phone use and one rare type 

of glioma, neuroepithelliomatous tumors. It is possible with multiple 

comparisons of the same sample that this association occurred by 

chance. Moreover, the risk did not increase with how often the mobile 

phone was used, or the length of the calls. In fact, the risk actually 

decreased with cumulative hours of mobile phone use. Most cancer 

causing agents increase risk with increased exposure. An ongoing 

study of brain cancers by the National Cancer Institute is expected to 

bear on the accuracy and repeatability of these results.(1)
