The potential risk of using cell phone to human bodies has been a concern for quite some time. Although no solid link has been established between cancer and cell phones, some scientists suggest taking a precautionary approach in the light of recent studies that indicate the possibility of such a connection.Each cell phone is embedded with a small radio transmitter inside to communicate with the telephone network. While some people are worried that the radio frequency may seep into brain tissue, damages cell and cause tumors, years of research and experiments have failed to prove the theory.
But recently, some new studies are starting to show that long-term use of these mobile devices may pose a threat to our health. According to Environmental Working Group, a government watchdog group, people who have used cell phones for at least 10 years face higher risk of brain and mouth cancers.
Nevertheless, CTIA – the Wireless Association, disagrees with the study by saying "scientific evidence has overwhelmingly indicated that wireless devices do not pose" a health hazard to human beings. The Food & Drug Administration also express a similar view on its Web: "the weight of scientific evidence has not linked cell phones with any health problems".
Despite their different standpoints, they all share the same view on the need for more research. For instance, the U.S. National Institute of Environmental Health Sciences is funding a large-scale animal testing, which exposes rodents to the same levels of radiation as humans are when using handsets. But the results won’t be available until sometime in 2013.
Until we have firm results on the issue, cell phone users who might be worried about the possible health threat can take several precautions by using speakers, wired handsfree devices or wireless Bluetooth headsets. You can also choose a low-radiation phone and use text messaging instead of voice calls if possible.
