Does Cell Phone cause cancer?
There have been several studies about the effect of radiation caused by cell phone to humans especially if it could cause cancer. Although cell phones emit a small amount of radiation, it is not considered harmful to humans.
If you are really worried about it, you can lessen your exposure to the radiation by using a hands-free earpiece or a car kit antenna. And try keeping the antenna as far as possible from your head. Also using the hands-free earpiece can lessen the risk of accidents if driving while using the cell phone.
