Cellphones are dangerous / not dangerous: Danish chatterbox edition

Concerned that a decade and a half of regular cellphone will have a long-term effect on your health? Hopefully the latest study conducted by members of the World Health Organization (WHO) will put your mind at ease. The examination followed nearly 3 million Danish adults, studying links between phone use and the formation of acoustic neuromas -- non-cancerous, slow-growing brain tumors that form on the main nerve that connects the inner ear to the brain. The study concluded that people who've used a handset for 11-15 years weren't any more likely to develop a tumor than those who don't use cellphones at all, though scientists are unsure that this is a long enough period of time to determine a significant correlation (or lack thereof). Still, this comes as refreshing news two months after the WHO released a study revealing that RF waves coming from phones are "potentially carcinogenic," due to a limited link to glioma and acoustic neuroma. Of course, none of these reports can actually conclude that cellphones cause cancer -- only that the two may be correlated. So, what does this latest study really do? It legitimizes the need to conduct more studies.
