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. 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.
What is FDA's role concerning the safety of mobile phones?
Under the law, FDA does not review the safety of radiation- 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 radiation at a level that is ha zardous to the user.
In such a case, FDA could require the manufacturers of mobile phones to notify users of the health hazard and to repair,
replace or recall the phones so that the hazard no longer exists.
Although the existing scientific data do not jus tify FDA regulatory actions at this time, FDA has urged the mobile
phone industry to take a number of steps to assure public safety. The agency has recommended
that the industry:
" support needed research into possible biological effects of RF of the type emitted by mobile phones;
" design mobile phones in a way that minimizes any RF exposure to the user that is not necessary fordevice function ;
and
" cooperate in providing mobile phone users with the best possible information on what is known about possible effects
of mobile phone use on human health.
