Analog mobile phones can cause tumors after long-term use

Ten or more years of mobile phone use increases the risk of developing acoustic neuroma, a benign tumor on the auditory nerve, according to a study released on Wednesday by Sweden's Karolinska Institute.

The risk was confined to the side of the head where the phone was usually held and there were no indications of increased risk for those who have used their mobile for less than 10 years, the Karolinska Institute said in a statement.

The institute, one of Europe's largest medical universities and a clinical and biomedical research center, awards the Nobel Prize in physiology or medicine.

"At the time when the study was conducted only analog mobile phones had been in use for more than 10 years and therefore we cannot determine if there results are confined to use of analog phones or if the results would be similar also after long-term use of digital (GSM) phones," it said.
