occurred in only a small number of cases, the increased likelihood was too
small to be statistically significant.(4)
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.
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 hazardous 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 justify 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:
