An estimated 275 million people in the United States and 4 billion-use cell phones worldwide.

A recent review of studies assessed whether there was epidemiologic evidence for an association between long-term cell phone usage and the risk of developing a brain tumor.

In order to be included in the analysis, studies were required to have been published in a peer-reviewed journal, included participants who had used cell phone for 10 or more years, and analyzed the side of the brain tumor relative to the side of the head preferred for cell phone usage. Eleven long-term epidemiologic studies fit the criteria.

The results indicated that using a cell phone for 10 or more years approximately doubles the risk of being diagnosed with a brain tumor on the same side of the head as that preferred for cell phone use.

Iowa senator Tom Harkin, newly empowered to investigate health matters as chairman of the Senate Health, Education, Labor and Pensions Committee, has promised to probe deeply into any potential links between cell phone use and cancer.

Harkin, who took over the committee after the death of Massachusetts Senator Edward Kennedy, said he was concerned no one has been able to prove cell phones do not cause cancer. A staffer said the senator became concerned by a report from the Environmental Working Group showing that radio wave emissions vary from one cell phone brand and model to another, as well as some reports suggesting there might be a link.

Dangers Known for a DecadeCell phones use radio waves to transmit voice data, and the dangers of consistent exposure to information-carrying radio waves have been known since at least 1998. Yet few have been willing to accept the evidence, and the cellular industry has followed in the footsteps of the tobacco industry, vehemently denying any risks.

It’s worth remembering that the telecommunication industry is even BIGGER than Big Pharma, and they have far more influence than the drug companies.

To get a better understanding of the physics and biological impact of information-carrying radio waves and the electromagnetic fields emitted from your cell phone, please review the article, "If Mobile Phones Were a Type of Food, They Simply Would Not be Licensed."

The first major indication that cell phones might be a health hazard came out of a massive, $28 million research project funded by the Cellular Telephone Industry Association (CTIA). To the industry’s surprise and dismay, the results of the study came to the opposite conclusion from the one they were hoping for.

The study's results included findings of:A nearly 300 percent increase in the incidence of genetic damage when human blood cells were exposed to radiation in the cellular frequency band

A significant increase in cell phone users’ risk of brain tumors at the brain’s outer edge, on whichever side the cell phone was held most often

A 60 percent greater chance of acoustic neuromas, a tumor affecting the nerve that controls hearing, among people who had used cell phones for six years or more

A higher rate of brain cancer deaths among handheld mobile phone users than among car phone users (car phones are mounted on the dashboard rather than held next to your head)

Prior to this, Alfred Gilman and Martin Rodbell had won the Nobel Prize (1994) for their research showing your body's cells communicate with each other by subtle low electromagnetic signals. These signals carry all the vital information that are then translated into biochemical and physiological processes.

The following year, researchers discovered that animals exposed to cell phone radiation suffered double-strand DNA breakage – the type of genetic alterations that can lead to cancer, cell death and mutagenic problems.

Since then, many more scientists confirmed all of the above findings.

The latest meta-analysis looks at the epidemiological evidence of cell phone usage and your risk of developing a brain tumor.

Eleven long-term epidemiologic studies were included, which led to the following findings:

“The results indicate that using a cell phone for > or = 10 years approximately doubles the risk of being diagnosed with a brain tumor on the same ("ipsilateral") side of the head as that preferred for cell phone use.

The data achieve statistical significance for glioma and acoustic neuroma but not for meningioma.

The authors conclude that there is adequate epidemiologic evidence to suggest a link between prolonged cell phone usage and the development of an ipsilateral brain tumor.”

So far, in addition to the widespread concern about brain cancer, scientists have found that information-carrying radio waves transmitted by cell phones and other wireless devices can:
