Last week, three famous neurosurgeons told the CNN interviewer Larry King that they do not hold cellphones next to their ears. Dr. Keith Black, a surgeon at Cedars-Sinai Medical Center in Los Angeles as well as Dr. Sanjay Gupta, a neurosurgeon at Emory University Hospital said that they use earpieces so you keep the microwave antenna away from your brain. The other neurosurgeon, Dr. Vini Khurana, an associate professor of neurosurgery at the Australian National University also said that he uses it on the speaker-phone mode and do not hold the cell to his ears.
It is not clearly defined if the cellphone causes cancer; however, vast numbers of studies that have been published in scientific journals around the world show that wireless phones do pose a health risk.
Cellphones emit non-ionizing radiation, waves of energy that are too weak to break chemical bonds or to set off the DNA damage. There is no explanation if this wave leads to cancer yet but researchers say that just because science can’t explain the mechanism doesn’t mean one doesn’t exist. They claim that since the heat generated by cellphones and the fact that the radio frequencies are absorbed mostly by the head and neck, there are good chances of risk. Supporting that, in recent studies, the tumors tend to occur on the same side of the head where the patient typically holds the phone. Not only that but also some of the research suggests a link between cellphone use and three types of tumors: glioma; cancer of the parotid, a salivary gland near the ear; and acoustic neuroma, a tumor that essentially occurs where the ear meets the brain.
What is more concerned is that more and more children are using cellphones. Since their brain is still in the process of growing and their skulls thinner, they have more chances to be in risk.
It is much early to reach a conclusion that cellphones are either safe or not safe yet it is no harm to be careful.

Nowadays, there are not many people without cellphone. Especially in Korea, most of the people including young and old have their own cellphones to carry. Starting from the moment they wake up, during breakfast, lunch, and dinner, during spare time, during classes, upto the end of the day when they go to sleep, people always carry cellphone with them and use it continuously. Since the market is almost saturated in Korea, the cellphone companies including Samsung are expanding their market to the other countries abroad. Yet if the concerns about cellphone continue on, those companies would meet a big downturn of the market.
The only way not to do so is to differentiate their products. Of course companies like Samsung have more advanced technology than other firms and have big technological potentials. It is nice to have camera, MP3 and other stuff in the cell yet what the customers need right now is the cellphone that does no harm to their health: that is the differentiation point that they need to make.
