If you're someone who's constantly on a cell phone, this should make you feel a little better about your habit.
Some have worried that cell phone use may lead to brain tumors. A study of nearly a thousand brain tumor patients measured all their minutes with that little phone up against their ears and found that cell phones are unlikely to trigger the most common type of brain tumor. It's called a glioma. The report is in the British Medical Journal, but more studies are planned.
