It's a wireless world we live in! should i be worried about emf exposure in the home? does it cause cancer?

Low risk: Cell phones, held directly to your head, are probably the highest RF radiation that people are exposed to and yet there has been no spike in brain cancer incidence. The jury is still out as to whether there is a cancer risk on a population basis, but the risks to an individual must be very small. If your worried, then connect your cell phone to a headset or use as a speaker phone.
