Man-talking-cell-phoneSwedes who talked on mobile or cordless phones for more than 25 years had triple the risk of a certain kind of brain cancer compared to those who used wireless phones for less than a year, a new study suggests. The odds of developing glioma, an often-deadly brain cancer, rose with years and hours of use, researchers reported in the journal Pathophysiology. “The risk is three times higher after 25 years of use. We can see this clearly,” lead researcher Dr. Lennart Hardell said in a telephone interview. His finding contrasts with the largest-ever study on the topic—the international Interphone study, which was conducted by the International Agency for Research on Cancer and funded in part by cell phone companies. That study, published in 2010, failed to find strong evidence that mobile phones increased the risk of brain tumors. More
