Danish researchers have found no support for Lennart Hardell and Kjell Hansson Mild’s contention that mobile phones increase the risk of acoustic neuromas. A team led by Christoffer Johansen of the Danish Cancer Society in Copenhagen compared the histories of 106 cases of acoustic neuromas, benign tumors of the cranial nerve, with those of 212 controls. There was no elevated rate of cancer, even among those who had used a cell phone for ten years or more.
