Scientists Study Cell Phones As Cause of Brain Tumors

The world's most comprehensive study of the health effect of cell phone use, two years overdue, has yet to be published. But some of the studies that contribute to the report are raising old concerns about the long-term safety of using wireless technology, according to the Toronto Star.

The World Health Organization's International Agency for Research on Cancer expects to complete work on its 13-nation, 50-scientist collaboration soon. The intent is to define what, if any, risk of cancer comes from prolonged use of cell phones.

It "involves the pooled analysis of thousands of cases of tumours in the head and neck area: gliomas, meningiomas, acoustic neuromas and parotid gland tumors," the Star reports. Until now, authoritative research had supported the overall safety of cell phones, but some say the newly widespread use of cell phone technology, and the prolonged use over years, could represent risks that weren't adequately tested in earlier studies.
