Two draft reports from the National Toxicology Program (NTP) offer mixed findings on a potential association between cell phone use and cancer.
Researchers conducted studies in which rats and mice were exposed to varying levels of radiofrequency radiation (RFR) for roughly 9 hours a day for up to 2 years. Among the findings:
“The levels and duration of exposure to RFR were much greater than what people experience with even the highest level of cell phone use and exposed the rodents’ whole bodies. So, these findings should not be directly extrapolated to human cell phone usage,” said an NTP senior scientist in a news release.
“We note, however, that the tumors we saw in these studies are similar to tumors previously reported in some studies of frequent cell phone users.”
