WITH such a large rise in mobile phone users around the world over the last 10 years,many people are worried about possible health risks. For some time,scientists have been thinking that mobile phones could lead to cancer. But so far,there is no strong evidence (證據(jù)) for this.

The Norwegian Institute of Public Health and theUK's Health Protection Agency both reported some studies last year. They said that there was no evidence found between mobile phone radiation (輻射) and cancer.

However,many heavy users of mobile phones often complain of headaches and even feeling sick. Last October,a court case inItalysaid that heavy mobile phone usage had caused brain cancer in one man. He had used a mobile phone up to six hours a day for 12 years.

But the biggest problem with research now is that it is too early to reach conclusions. Mobile phones have only been widely used since the 1990s,and cancers can take many years to develop.

There is also still a strong argument that mobile phones are a major risk for children. "In a child,the more central brain structures are going to be exposed (暴露) ”， said Dr Annie Sasco of the Institute of Public Health,speaking to the BB   C. She added, "Besides,kids have a skull (頭蓋骨) which is thinner. There is much more water in their brain. So there are many reasons that they take in more of the same radiation."
