On call: Cell phones and hospitals
Cell phones and hospitals
Q. When I visited a friend in the hospital recently, I was annoyed that I was not allowed to use my cell phone. Are cell phones really dangerous?
A. Ever since they became popular, cell phones have provoked controversy. Because they emit radio-frequency fields, they've been blamed for everything from cancer to pacemaker malfunction. But the facts are reassuring.
Cancer is not a realistic worry. One study evaluated 420,095 Danish people who had been using cell phones for up to 21 years. Confirming earlier studies, the scientists found no link between cell phone use and cancer, including tumors of the acoustic nerve in the ear, the salivary glands, the eyes, or the brain.
