Using a cell phone for long periods could lead to malignant brain tumors, says a new study contradicting earlier findings that found no such link.
Earlier studies did not find evidences that radiation from cell phones was linked with elevated brain tumor risk although the damaging effect of cell phone use has been suspected for long.
Researchers led by Kjell Mild, of the Swedish National Institute for Working Life, compared cell phone use of 2,200 patients with malignant tumors and an equal number of healthy control cases.
Among the tumor patients (aged 20 to 80), 905 had a malignant brain tumor and one third of them were heavy users of cell phones, it said.
"Of these 905 cases, 85 were high users of mobile phones," the study authors said.
Children should avoid using cell phones whenever possible because they are most vulnerable to tumor risk than adults, the study warned.
