Cell phones are a carcinogenic device, which means they can cause cancer. Cell phones have the same amount of carcinogenic risk as lead, engine exhaust, and chloroform. WHO found that radiation from cell phones is called non-ionizing. It's not like an x-ray, but more like a very low power microwave. The manufacturers of many popular cell phones already warn consumers to keep the device away from the body in other ways to minimize cell phone radiation. Ultimately, cell phones emit the most radiation when they attempt to interface with cell towers. A moving phone or a phone in an area with a weaker signal has to work harder, emitting more radiation. People should avoid using cell phones in areas such as elevators, buildings and rural areas if they want to reduce their exposure. In 2011, the World Health Organization defined the type of low-vital radiation transmitted by cell phones as “potentially carcinogenic” due to a connection between phone use and a kind of dangerous brain tumor called glioma and a benign brain tumor called acoustic. neuroma (Dellorto). According to Dellorto, “children's skulls and scalps are thinner. This allows radiation to penetrate deeper into the brains of children and young adults. Their cells divide at a faster rate, so the impact of radiation can be much greater”,
