"That might potentially mean that people who are genetically predisposed are at a greater risk by using cell phones but, over the years the effect washes out because people who were going to get tumors already got them," said Dr. Michael Schulder, vice chairman of neurosurgery at the Cushing Neuroscience Institute of the Hofstra North Shore-LIJ School of Medicine in Manhasset, N.Y.
One limitation of the new study is that the authors weren't able to look at how long or often people used their cell phones or if, in fact, they used them at all, Kornel noted.
Despite the findings, it's unlikely that the question of a link between brain cancer and cell phone use will be answered to everyone's satisfaction anytime soon.
In the meantime, there are some common-sense measures people can take to reduce any risk there might be.
"Rather than clamp the cell phone to the side of your head, use an earpiece with a wire," advised Schulder.
Dr. Jay Brooks, chairman of hematology/oncology at Ochsner Health System in Baton Rouge, La., said, "If you're going to use a cell phone, I'd try to use it as little as you need to."
He added, though, that he did not believe that "the risks, if any, are very great."
But the biggest danger from cell phones may not be from brain cancer.
"The biggest risk incurred from cell phones is during driving," said Schulder. "If you studied 10 million people for 100 years, the risk from texting while driving, looking at emails, holding the phone with your hand to your head and probably, to some extent, even talking on the phone are all far greater than anything that might ever show up in a study like this."
