Cell phones more dangerous than smoking?

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?
