We don’t know for sure yet; people haven’t been using the technology long enough for us to be sure of the health effects.
So far there is no overwhelming evidence that cell phones cause brain tumours, or other serious health effects in humans.
Nevertheless, studies have turned up enough disturbing findings to warrant caution in how much we use cell phones.
For example, it appears that cell phone use causes temporary raised blood pressure in blood vessels in the head, which may be dangerous for people at risk for stroke or heart attack. Other studies have found that cell phone radiation causes cell damage in animal test subjects. Medical experts remain concerned about the long-term effects of cell phone use on children’s developing brains.
