Health risks

Because mobile phones emit electromagnetic radiation, concerns have been raised about cancer risks that may pose when used for long periods of time.[21] This radiation is non-ionizing, but localized heating can occur. The current consensus view of the scientific and medical communities is that health effects are very unlikely to be caused by cellular phones or their base stations

Cellular phones became widely available only relatively recently, while tumors can take decades to develop. For this reason, some health authorities have urged that the precautionary principle be observed, recommending that use and proximity to the head be minimized, especially by children.
