Rat Study Finds No Cell Phone - Cancer Link Tue Jun 25, 1:21 PM ET NEW YORK (Reuters Health) - Rats exposed to the type of radiation emitted from cell phones do not show an increase in cancer risk, according to the results of a new study. Cell phones emit low levels of radiation that some researchers suggest may be powerful enough to damage DNA, potentially promoting cancer. But other evidence indicates that the radiation that may be absorbed from cell phones is not powerful enough to inflict genetic damage. Despite a number of studies, scientists have yet to decide whether there is a link between cell phone usage and cancer, particularly brain tumors. Studies are often funded by the wireless industry. And while many have uncovered no increased rates of brain cancer with cell phone use, health officials have said the possibility of a link cannot yet be ruled out. In the current investigation, a team of researchers monitored cancer rates in 480 male and female rats exposed to cell phone radiation for 4 hours a day, 5 days a week for a 2-year period. The rodents were exposed to radiation from either one of the two common cell-phone radio frequencies: analog or digital. A third, "control" group of rats was exposed to no radiation. The study was supported in part by funding from Motorola Inc., a manufacturer of cellular phones. "We tried to mimic a high level of exposure that humans might experience," said the study's lead author, Dr. Joseph L. Roti of the Washington University School of Medicine in St. Louis, Missouri, in a prepared statement. "We found no statistically significant increase in any tumor type, including brain, liver, lung or kidney compared to the control group," Roti said. The findings are being presented this week by Roti and his team at the Bioelectromagnetic Society meeting being held in Quebec City in Quebec, Canada.
