We've heard the warning before, but now it's an official alert. Cell phone use may cause cancer. That's the world from the World Health Organization.
According to a group of 31 scientists from 14 countries, there is not enough long-term data to link cancer and cell phone use directly. However, officials believe there is enough information to issue an alert.
With this latest announcement, WHO now groups cell phones in the same hazard category as chloroform, lead, and engine exhaust.
The report comes as a proposed class action lawsuit against 19 defendants, mostly cellphone manufacturers and telecommunications companies, has landed at the Supreme Court. The defendants -- which include Nokia, AT&T and Samsung -- are accused of misrepresenting that their cellphones are safe, when they in fact knew of potential dangers.
