Dr. Hyla Cass on recent studies on cell phone radiation and related medical risks

Both Cell phones and electromagnetic fields are more dangerous than widely assumed, as growing numbers of news reports and academic studies are pointing out.
Hyla Cass, M.D., "Are Cell Phones and Wi-Fi Hazardous to Your Health?," Huffington Post, October 13, 2010.
She cites two recent books, Ann Louise Gittleman's "Zapped: Why Your Cell Phone Shouldn't Be Your Alarm Clock and 1,268 Ways to Outsmart the Hazards of Electronic Pollution." and
Devra Davis' "Disconnect: The Truth About Cell Phone Radiation, What the Industry Has Done to Hide It, and How to Protect Your Family."
Key excerpts in Dr. Cass' Huffington Post article:

The UK's BioInitiative Report of July 2007 (updated in 2009) describes hundreds of studies that link EMF exposure to Alzheimer's disease, ALS (Lou Gehrig's disease), brain fog, cardiovascular disease, miscarriage, infertility, insomnia, learning impairment, as well as anxiety and depression. Wireless technologies -- like cell and cordless phones -- produce microwaves that increase the permeability of the blood-brain barrier, leading to changes in brain chemistry. Even low-level EMFs can cause brain cells to leak.

That's not all: Although actual tissue heating does not occur, EMFs also cause breaks in DNA, speed up cell division, disrupting the orderly process of chromosome matching and detaching, and activate stress protein or heat shock proteins. And as Anne Louise Gittleman writes in Zapped:

"Most disturbing of all, the Swedish National Institute for Working Life found that people using cell phones for 2,000 hours -- a total most of us could easily rack up over the years -- had a 240 percent increased risk for malignant brain tumors on the side of the head where they usually held their phone."

A related study from the Mercury News:

An excerpt from this article reads,

Several players at the heart of this debate converged on San Francisco last week. CTIA-The Wireless Association had

its annual trade show, which it promised would be the last in the city because of the new disclosure law. Marks organized several protests outside the event. And noted epidemiologist Devra Davis, a visiting professor at Harvard University, arrived for several speaking engagements about her recently published book, "Disconnect: The Truth About Cell Phone Radiation, What the Industry Has Done to Hide It, and How To Protect Your Family."

"When I first heard that there could be problems with cell phones, I didn't believe it," Davis said. "I wrote the book because I was stunned to find out I was wrong to assume that these things had to be safe."

For many years it was believed the low levels of radiation generated by cell phones and towers had no effect on human biology. Now a small but growing number of scientists and health activists are challenging those findings.
