More Proof Long-Term Use of Cellular Phones is as Unhealthy as Cigarettes A new large-scale study has shown that long-term users of mobile phones are much more likely to develop a certain type of brain tumor on the side of the head where they hold their handsets. Those who regularly used mobiles for longer than 10 years were almost 40 percent more likely to develop nervous system tumors called gliomas. This is the second study to suggest an increased brain tumor risk associated with mobile phones. The study examined more than 1,500 people with gliomas, and an additional 3,300 people who did not suffer from the cancers. Scientists at first found no link between cellular phones and tumors, until they specifically reviewed the medical histories of patients who had been using mobiles for at least a decade.
