If you are a physician and someone comes to see you with an absolutely incapacitating headache or a swollen arm, you don't tell them, "Come back in 10 years when I've completed my study and I'll see what I can do for you."

The reality is, cellphones have to be used safely. They are today like cars and trucks - we can't live without them, but we certainly wouldn't give a car or truck to a toddler to drive. Why are we thinking it's perfectly okay to give a device that the World Health Organization has said is a "possible human carcinogen" to infants and toddlers, and for that matter, schoolchildren?

Where people are using phones in rural areas their risk of brain cancer is higher than in urban areas.

We get dopamine in the brain when we like something a lot. Well, cellphones stimulate dopamine, too. So it really is the case that there are some people who are pretty addicted to these devices.

Cellphone and other wireless radiation should be classified as a "probable human carcinogen."

The question is, do you want to play Russian roulette with your brain?

The average studies of cellphones and brain cancer have studied people who have used cellphones for five years or less. Sometimes eight years. Every study that has actually examined people who have used phones for 10 years or more, and is well designed, finds a 50 percent to an 800 percent increased risk. So that is why the Israelis, the Finnish, the French governments have all issued warnings.
