The use of mobile phones is not linked to cancer, according to a new joint Danish-American study. "We found no increased risk of brain tumors, acoustic neuromas, salivary gland tumors, eye tumors, leukemias or overall cancer," report researchers from the Danish Cancer Society in Copenhagen and the International Epidemiology Institute (IEI) in Rockville, MD. This was the case for both short-term and long-term users. Their results appear in tomorrow's edition of the Journal of the National Cancer Institute (JNCI).
