Cancer Cell Calls
According to a Swedish study, spending at least an hour a day using a cell phone over many years raises the chance of suffering from a brain tumor by 240 percent, compared with someone who never uses a cell phone. The tumors were more likely to appear on the side of the head where users placed their phones.
The simple answer, conclude researchers, is to use a hands-free headset when making cell-phone calls, though it isn’t clear on what part of the body a caller should wear a phone and not be affected by radiation. The studies were noteworthy because they provided very different conclusions from earlier work that found no link between phone use and cancer. For instance, a four-year British study concluded in 2005 that cell-phone use didn’t lead to glioma, a common type of brain tumor.
