Why the Largest Study Ever on Cellphones and Cancer Won’t Settle the Debate
Research found small increases in tumors and DNA damage in some rats; ‘No smoking gun’
U.S. researchers spent nearly two decades to design and carry out a definitive study on the health effects of cellphone radiation. The final results, released Friday, are likely to fuel rather than dispel the long-running debate about the planet’s most ubiquitous electronic device.
Among the observations: Male rats exposed to the radiation had small increases of tumors in their hearts and brains. Females didn’t. Exposed animals also showed signs of DNA damage, which experts thought wasn’t possible. But they also lived longer...
