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.

Radar, of course, is what cellphone radiation is exactly like. It can be a similar frequency, it's just much weaker power.
