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.
What is FDA's role concerning the safety of
mobile phones?
Under the law, FDA does not review the safety of radia-
tion emitting consumer products such as mobile
phones before marketing, as it does with new drugs or
medical devices. However, the agency has authority to
take action if mobile phones are shown to emit radia-
tion at a level that is hazardous to the user. In such a
case, FDA could require the manufacturers of mobile
