A renowned neurosurgeon and cancer expert recently made strong statements against cell phones, warning that regular use could double a person's risk of developing brain cancer. Though studies have refuted the claim that radiation from cell phones can be damaging, Dr. Vini Kurana says that that research did not take into consideration that most cancers take 10 years to develop and were too short-sighted.

Dr. Kurana went as far to say that cell phones could be more dangerous than smoking or asbestos and called on government officials to regulate their use. That's a pretty radical statement -- more dangerous than smoking? I'm doubtful that one man's research will change the habits of millions of cell phone users around the world, but still...I'd like to hear more. What do you think?

Though it never seemed to slow the use of cell phones, there's been an undercurrent of worry for years that their use may cause the most common type of brain tumor -- a glioma.

Mobile phone users have little reason to worry following a study that found that cell phone use appears to have no link to the development of this kind of tumor. Researchers studied1,521 glioma patients and over 3,000 healthy patients and found no relationship between cell phone use and the cancer. There was a "borderline statistical significance," however, between those who used cell phones for more than 10 years on one side of the head, which was also on the same side of the tumor, but researchers can't say that that finding is truly meaningful.
