It's one of the most debated issues involving cell phones: whether or not they cause brain tumors. According to a new study, the answer is no.
The study, which looked at 2.8 million Danish adults, found that those who had used a cell phone for more than 10 years were no more likely to develop a non-cancerous type of brain tumor than adults who had never used a cell phone or those who had used one for a shorter period of time.
The type of tumor studied was an acoustic neuroma, which is a slow-growing, non-cancerous tumor that forms inside the brain, near the ear. While these tumors are non-cancerous, they are considered an important indicator of the safety of cell phones.
"Of interest is that acoustic neuromas grow in the area of the brain where greater energy emitted from the cellphones is absorbed, compared to other areas of the brain," the study's leader, Dr. Joachim Schuz of World Health Organization's International Agency for Research on Cancer, told Reuters.
