Study of Cellphone Risks Finds ‘Some Evidence’ of Link to Cancer, at Least in Male Rats

(NY Times) For decades, health experts have struggled to determine whether or not cellphones can cause cancer. On Thursday, a federal agency released the final results of what experts call the world’s largest and most costly experiment to look into the question. The study originated in the Clinton administration, cost $30 million and involved some 3,000 rodents.

The experiment, by the National Toxicology Program, found positive but relatively modest evidence that radio waves from some types of cellphones could raise the risk that male rats develop brain cancer.

“We believe that the link between radio-frequency radiation and tumors in male rats is real,” John Bucher, a senior scientist at the National Toxicology Program, said in a statement.
