Radiation from cell phones can possibly cause cancer, according to the World Health Organization. The agency now lists mobile phone use in the same "carcinogenic hazard" category as lead, engine exhaust and chloroform.

A team of 31 scientists from 14 countries, including the United States, made the decision after reviewing peer-reviewed studies on cell phone safety. The team found enough evidence to categorize personal exposure as "possibly carcinogenic to humans."

What that means is they found some evidence of increase in glioma and acoustic neuroma brain cancer for mobile phone users, but have not been able to draw conclusions for other types of cancers

Wireless industry responded to Tuesday's announcement saying it "does not mean cell phones cause cancer."

CNN 报道世界卫生组织WHO 最新的公告已经将手机和铅、发动机排气，和氯仿并列成为了有致癌风险。

据说包括美国在内的14个国家31个科学家共同研究审查出来了这个结果。这表示科学家们已经找出了一些证据表明手机能够导致或者增大脑神经癌症的迹象。

而手机的辐射更像是微波炉的辐射，来自洛杉矶的Keith Black 博士说“这就好像手机在微博你的大脑一样。”

但手机无线行业却认为这是无稽之谈。
