He cites laboratory studies in mice and in test tubes that he says suggest there may be genetic damage from cell phone use. He says some studies have found an increase in certain rare cancers among cell phone users. Carlo says studies such as the Danish one looking at trends in cancer rates among cell phone users are inadequate. No matter which way we looked at our data, we could not find any evidence or even a suggestion of elevations in any cancer. Boice says the study was funded with grants from two Danish companies that supply cell phone service and from his institute, which has no connection to the industry.
More studies are underway.
The Food and Drug Administration has signed an agreement with the Cellular Telecommunications Industry Association to conduct more research together, and the National Institutes of Health also is looking at possible health problems resulting from cell phone use. The industry says more than 106 million Americans use cellular phones, and that is growing by about 67,000 new users each day.
