IARC: Cell Phone Radiation Is a Possible Human Carcinogen

Testify on non-ionizing RF radiation in general, not directly about cell phone. 

Zaret was the first medical doctor to testify in Congress on the hazards of microwaves. On March 9, 1973, he told a hearing convened by then Senator John Tunney of California:

"There is a clear, present and ever-increasing danger to the entire population of our country from exposure to the entire non-ionizing portion of the electromagnetic spectrum. The dangers cannot be overstated because most non-ionizing radiation injuries occur covertly, usually do not become manifest until after latent periods of years, and when they do become manifest, the effects are seldom recognized."
