"Scientists Question Industry-Funded Research and Say FDA Should Probe Possible Link To Cancer" Claim Wireless Phones May Cause Brain Tumors Cell phones are no longer a symbol of affluence but a must-have form of communication now used by some 70 to 100 million Americans. But their use has also spawned a debate on safety, reports CBS News Correspondent Sandra Hughes. . . . Dave Reynard, a widowed Florida businessman, was expecting more concrete information [from a $25 million study by the cell phone industry]. Reynard lost his wife to a brain tumor he says was caused by her cell phone. "She had a tumor the size of a golf ball right here on the side of her head which is where the antenna would go when you're using the phone," Reynard said. Just before her death, Susie Reynard videotaped a deposition for a lawsuit. "We didn't realize they were bad for you," she said in her statement. The editor of Microwave News, an industry publication, says consumers should be outraged. "Basically the industry has not honored its commitment to the American public to get to the bottom of this," Louis Slesin says. "Even if it's a small risk, we're talking on a societal basis a very large problem." The cell phone industry vigorously defends its research as fair and independent.
