Another day and another study, this time one that decides mobile phones can cause brain tumors. Researchers at the Swedish National Institute for Working Life have concluded there is a link:

Kjell Mild, who led the study, said the figures meant that heavy users of mobile phones, for instance of who make mobile phone calls for 2,000 hours or more in their life, had a 240 percent increased risk for a malignant tumor on the side of the head the phone is used.

However, the study only used people that had brain tumors and then researchers went back to find a link.
