A government report could heat up the debate over cellphone use and cancer. A study by the Department of Health and Human Services's National Toxicology Program discovered a link between cellphone radiation and two types of cancer. Reporting on its partial results so far, researchers found low incidences of heart and brain tumors in male rats. The report said, "...even a very small increase in the incidence of disease resulting from exposure to radio frequency radiation could have broad implications." The rodents were exposed to the two common radio frequencies used in U.S. wireless networks, GSM and CDMA, for nine hours every day over two years. Other studies have indicated that it's safe to use cellphones despite the radiation they give off. Government researchers say they'll come out with more data on the impact on rats in two forthcoming reports.
