association was found between mobile phone use and one rare type of

glioma, neuroepithelliomatous tumors. It is possible with multiple

comparisons of the same sample that this association occurred by

chance.

Moreover, the risk did not increase with how often the mobile phone was

used, or the length of the calls. In fact, the risk actually decreased with

cumulative hours of mobile phone use. Most cancer causing agents

increase risk with increased exposure. An ongoing study of brain cancers

by the National Cancer Institute is expected to bear on the accuracy and

repeatability of these results.

2.Researchers conducted a large battery of laboratory tests to assess the

effect of exposure to mobile phone RF on genetic material. These included

tests for several kinds of abnormalities, including mutations, chromosomal

aberrations, DNA strand breaks, and structural changes in the genetic

material of blood cells called lymphocytes. None of the tests showed any

effect from the RF except for the micronucleus assay, which detects

structural effects on the genetic material. The cells in this assay showed

changes after exposure to simulated cell phone radiation, but only after 24

hours of exposure. It is possible that exposing the test cells to radiation for

this long resulted in heating. Since this assay is known to be sensitive to

heating, heat alone could have caused the abnormalities to occur. The

data already in the literature on the response of the micronucleus assay to

RF are conflicting. Thus, followup research is necessary.

FDA is currently working with government, industry, and academic

groups to ensure the proper follow-up to these industry-funded

research findings. Collaboration with the Cellular Telecommunications

Industry Association (CTIA) in particular is expected to lead to FDA

providing research recommendations and scientific oversight of new

CTIA-funded research based on such recommendations. 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 test.

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.

2.In 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. Because this

occurred in only a small number of cases, the increased likelihood was too

small to be statistically significant.

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 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 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
