The World Health Organization's International Center for Cancer Research recently said the use of mobile phones or other wireless communications devices "may increase the risk of cancer in humans," the statement by the wireless communications industry, a fierce retort.  As a result, the old debate over whether wireless communications devices can induce brain tumors is heating up again. The use of wireless communications equipment for human impact of scientific research is currently concentrated in two areas: first, the microwave heating phenomenon of human tissue damage. People who have used microwaves will notice that when certain electromagnetic waves radiate to food containing moisture, the food temperature will rise.  Some scientists suspect that when using a cell phone, the radiated electromagnetic waves heat the body and cause damage. The other is the damage of electromagnetic wave under the condition of non heating. In this respect, scientists have done a specific study in two different ways. The first is that electromagnetic waves can cause vasoconstriction. Senerios, a physicist at the University of Linkoping, Sweden, found that water molecules in cells have a very weak electrical power and thus form a gravitational pull between cells. This gravitational attraction is usually extremely weak, but it will increase dramatically under the influence of the electromechanical magnetic field of the hand.  Senerios speculated that the change was enough to cause blood vessels to contract and cause damage. Another potential danger is the cell phone's risk of cancer, such as brain tumors. In this respect, academic institutions and international organizations in a number of countries have conducted several large-scale and long-term surveys. In 2000, for example, the Journal of the American Medical Association reported that there was little link between the use of mobile phones and brain cancer. The following year, a report published by the Ministry of General Affairs of Japan said that there was no causal relationship between cell phone radiation and brain tumor onset. In 2006, the Danish Institute for Cancer Epidemiology reported that long-term follow-up of more than 420,000 mobile users showed that using mobile phones did not increase the risk of cancer. In 2008, the German Federal Agency for Radiological Protection reported that in a 10-year study, no use of mobile phones was found to cause cancer risk to adults.  Last year, the International Center for Cancer Research said it was not certain that using a cell phone would trigger a brain tumor. Various studies may draw different conclusions using different methods and different samples.  So so far, the use of mobile phones is still a problem of cancer is not fully solved. While some findings suggest there is no causal link between using mobile phones and cancer, one of the best ways to deal with potential threats is to prevent them. Among the many preventive measures, the World Health Organization and many Governments have emphasized that teenagers should be cautious about using mobile phones.  Teenagers ' ears and skulls are smaller and thinner than adults, and when they use their cellphones, the brain absorbs 50% more radiation than adults. For the sake of health, for the sake of safety, teenagers should minimize the use of mobile phones. (according to Xinhua news Agency)
