What is known about cases of human cancer that have been reported in users of handheld 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
What is FDA’s role concerning the safety of mobile phones?
Under the law, FDA does not review the safety of
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:
•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 for device 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.
At the same time, FDA belongs to an interagency working group of the federal agencies that have responsibility for different aspects of mobile phone safety to ensure a coordinated effort at the federal level. These agencies are:
•National Institute for Occupational Safety and Health
•Environmental Protection Agency
•Federal Communications Commission
•Occupational Health and Safety Administration
•National Telecommunications and Information Administration
•The National Institutes of Health also participates in this group.
In the absence of conclusive information about any possible risk, what can concerned individuals do?
If there is a risk from these products — and at this point we do not know that there is — it is probably very small. But if people are concerned about avoiding even potential risks, there are simple steps they can take to do so.
