expected to lead to FDA providing research recommendations and
scientific oversight of new CTIA-funded research based on such
recommendations.
Two other studies of interest have been reported recently in the
literature:
1. Two groups of 18 people were exposed to simulated mobile
phone signals under laboratory conditions while they
performed cognitive function tests. There were no changes in
the subjects' ability to recall words, numbers, or pictures, or
in their spatial memory, but they were able to make choices
more quickly in one visual test when they were exposed to
simulated mobile phone signals. This was the only change
noted among more than 20 variables compared.
2. In a study of 209 brain tumor cases and 425 matched
controls, there was no increased risk of brain tumors
associated with mobile phone use. When tumors did exist in
certain locations, however, they were more likely to be on the
side of the head where the mobile phone was used.
Because this occurred in only a small number of cases, the
increased likelihood was too small to be statistically
4
significant.
In summary, we do not have enough information at this point to
assure the public that there are, or are not, any low incident
health problems associated with use of mobile phones. FDA
continues to work with all parties, including other federal
agencies and industry, to assure that research is undertaken to
