Study links tumors to cell phone use
Consumer Affairs

A study in the international journal Epidemiology finds that people who have used cell phones for at least 10 years may have an increased risk of developing a rare brain tumor.

A research team from the Institute of Environmental Medicine at the Karolinska Institute in Stockholm, Sweden, found that using a cell phone for a decade or more quadrupled the risk of developing acoustic neuromas. The rare tumors generally occurred on the side of the head where the phone was most often held.

"We were surprised by the results," said Anders Ahlbom, professor of epidemiology at the institute and leader of the research team. "We think this is relatively strong data that is not down to chance."

The World Health Organization sponsored the research and medical and technology experts say it's likely to renew concerns about cell phone safety. They say it will be much harder for the industry to stonewall further medical research in this area.
