The French Interphone results are out and they are not reassuring.
The French study team, which includes Elisabeth Cardis, who is in charge of the overall Interphone project, has found high rates of brain tumors (gliomas) among heavy cell phone users. It's not a significant result, statistically speaking, but what is noteworthy is that this excess was apparent regardless of the way a heavy user was defined. As the researchers themselves put it: There is a "general tendency" for a greater glioma risk for "long-term users, heavy users [and] users with the largest numbers of telephones."
