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. *3

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.

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
provide the necessary answers to the outstanding questions about
the safety of mobile phones.
What is known about cases of human cancer that have been reported
in users of hand-held mobile phones?

Some people who have used mobile phones have been diagnosed
with brain cancer. But it is important to understand that this
type of cancer also occurs among people who have not used mobile
phones. In fact, brain cancer occurs in the U.S. population at a
rate of about 6 new cases per 100,000 people each year. ###203 At
that rate, assuming 80 million users of mobile phones (a number
increasing at a rate of about 1 million per month), about 4800
cases of brain cancer would be expected each year among those 80
million people, whether or not they used their phones. Thus it is
not possible to tell whether any individual's cancer arose because
of the phone, or whether it would have happened anyway. A key
question is whether the risk of getting a particular form of
cancer is greater among people who use mobile phones than among
the rest of the population. One way to answer that question is to
compare the usage of mobile phones among people with brain cancer
with the use of mobile phones among appropriately matched people
without brain cancer. This is called a case-control study. The
current case-control study of brain cancers by the National Cancer
Institute, as well as the follow-up research to be sponsored by
industry, will begin to generate this type of information.
