Without any ambiguity, the authors reveal "a causal link between the use of mobile phones and development of parotid gland tumors. And more the use of the phone is protracted, the danger seems more important. " The risk is (thus) increased 50% in people who use their phones for more than 22 hours per month" the authors said.
Another important point: the exposure is more dangerous in rural areas (where the transmitters are more powerful) than urbain. It's an important step that has just been crossed.

A new technology should (in effect) to be rapidly developed to reduce the risk of tumors associated with radiation.
