Surveillance, Epidemiology, and End Results (SEER) 
program of the National Cancer Institute
 
The National Cancer Institute (NCI) actively follows cancer 
statistics in the United States to detect any change in rates of 
new cases for brain cancer. If cell phones play a role in risk for 
brain cancer, rates should go up, as heavy cell phone use has 
been common for quite some time in the U.S. Between 1987 
and 2005, the overall age-adjusted incidence of brain cancer 
did not increase. Additional information about SEER can be 
found at http://seer.cancer.gov/.
Cell Phone Industry Actions
 
Although the existing scientific data do not justify FDA 
regulatory actions, the FDA has urged the cell phone industry 
to take a number of steps, including the following: 
Support-needed research on possible biological effects of 
RF for the type of signal emitted by cell phones;
Design cell phones in a way that minimizes any RF exposure 
to the user; and
Cooperate in providing users of cell phones with the current 
information on cell phone use and human health concerns.
The FDA also is working with voluntary standard-setting bodies 
such as the Institute of Electrical and Electronics Engineers 
(IEEE), the International Commission on Non-Ionizing Radiation 
Protection (ICNIRP), and others to assure that safety standards 
continue to adequately protect the public.
Reducing Exposure: Hands-Free 
Kits and Other Accessories
Steps to Reduce Exposure to Radiofrequency 
Energy
If there is a risk from being exposed to radiofrequency energy 
(RF) from cell phones - and at this point we do not know that 
there is - it is probably very small. But if you are concerned 
about avoiding even potential risks, you can take a few simple 
steps to minimize your RF exposure.
Reduce the amount of time spent using your cell phone;
Use speaker mode or a headset to place more distance 
between your head and the cell phone.
Hands-Free Kits
Hand-free kits may include audio or Bluetooth
®
 headsets and 
various types of body-worn accessories such as belt-clips and 
holsters.  
Combinations of these can be used to reduce RF energy 
absorption from cell phones.
