New research is casting doubt on a link between cell phone use and one type of non-cancerous brain tumor.
A study of Danish adults concludes those who used a cell phone for eleven to 15 years weren’t more likely than non-users to develop a tumor called an acoustic neuroma. The research also found the long-term users weren’t more likely to develop the tumor than those who used a cell phone for shorter periods of time. The tumors studied are slow-growing ones that occur on a nerve running from the inner ear to the brain. In a limited number of cases, the tumors can press on the brain and become a serious problem. Researchers looked at almost three-million adults in the study.
