Large Study Shows Recent, But Not Lifetime, Exposures Lead to Brain Tumors

Power-frequency magnetic fields can promote brain tumors, according to the largest epidemiological study of its kind ever undertaken. The study promises to breathe new life into the idea that extremely low frequency (ELF) EMFs are more likely to be cancer promoters than causes of cancer. This hypothesis gained support a generation ago but has lost currency in recent years.

The new results, published online earlier this month by the journal Cancer Epidemiology, Biomarkers & Prevention, come from INTEROCC, an international project with seven participating countries designed to investigate occupational health risks from chemicals and EMFs. The project is directed by Elisabeth Cardis at CREAL in Barcelona with $1.5 million from the U.S. National Institutes of Health (though none of the tumor cases are from the U.S.).

The INTEROCC team found that those who were exposed to elevated EMF exposures at work during the five years prior to diagnosis had significantly higher rates of glioma compared to those who were least exposed during that time on the job. The greater the exposure, the greater the tumor risk.

In 2011, Health Canada found itself in a tough spot. The public was becoming more and more uneasy over exposure to RF radiation from the proliferating number of cell phones, cell towers and Wi-Fi routers. After holding hearings in the spring and fall of 2010, Parliament asked the health agency to investigate whether its exposure limits —the Canadian national RF standard known as Safety Code 6 (SC6)— were too lenient and needed strengthening. Soon afterwards, the International Agency for Research on Cancer (IARC) added urgency to the assignment by classifying RF radiation as a possible human cancer agent, or, in the vernacular, a 2B carcinogen.

Health Canada’s dilemma was that it had no interest in tightening SC6. Yet IARC’s 2B designation could not be easily ignored, especially after France and Belgium, among other European countries, had responded by adopting precautionary policies. Last year, for instance, Belgium banned the sale of cell phones to children. How would Health Canada find a way to stick with the status quo?

The answer was to commission a review of SC6 by the Royal Society of Canada (RSC)

Industry Treads Water; Conflicts Abound

Five years ago we reported on what we thought was an important clue in the search for understanding the well-documented association between childhood leukemia and EMF exposure. A team based in Shanghai presented evidence that children carrying a genetic variation linked to DNA repair were four times more likely to develop leukemia than those without that genetic marker. We called the finding a “major breakthrough” and predicted, “It simply cannot be ignored.”

We were wrong. So wrong.

What happened next —or rather, what did not happen— sheds light on why EMF research treads water and never moves forward.

Video Illustrates the Wonders of Nature and Teaches Us a Lesson About Our EM World

Tuesday, January 7, 2014

When asked what he had learned about God from his studies of evolutionary biology, J.B.S. Haldane replied that the Creator has “an inordinate fondness of beetles” — after all, there are 400,000 different species of beetles and only 8,000 species of mammals. Take a look at this video and you might wonder whether red foxes are another of God’s favorite creatures. (Be sure to watch the clip in full screen mode.)

The red fox hunts by jumping up in the air and diving for its prey. As the narrator tells us, the fox can locate a mouse even when hidden under a deep pile of snow. It’s tempting to attribute a fox’s success to a keen sense of hearing or smell, but it turns out to be more complicated than that. A German-Czech team of researchers has found that red foxes have an added advantage: They can use the Earth’s magnetic field to home in on their target.

Danish Cancer Society Plays Games with Brain Cancer Rates

Just over a year ago, the Danish Cancer Society (DCS) issued a news advisory with some alarming news: The number of men diagnosed with glioblastoma, the most malignant type of brain cancer, had doubled over the last ten years. Hans Skovgaard Poulsen, the head of neuro-oncology at Copenhagen University Hospital was quoted in the release as saying that this was a “frightening development.”

At the time, Christoffer Johansen, a senior researcher at the DCS told us: “I think the data is true and valid.” And Joachim Schüz, a long time collaborator of Johansen’s at the DCS who is now at the International Agency for Research on Cancer (IARC) in Lyon told Microwave News that the news was “indeed a concern.” He said that he could not explain it. (See our report here.)

After that, there was silence.

INTEROCC and INTERPHONE have a lot in common —more than their first five letters. So much in common that it’s a bit freaky. Or, maybe it just shows, once again, how small, insulated and polarized the EMF community is.

The most obvious parallels are that Elisabeth Cardis is the principal investigator of both the...

The new INTEROCC paper raises an intriguing question: Might the ELF component of GSM phone radiation present a brain tumor risk?

To date, all the attention on the cancer risk from mobile phones has been on RF radiation. Now that INTEROCC points to a credible association between exposure to ELF EMFs and brain tumors (see main story), is it possible, we have been focusing on the...

Arthur W. Guy, known to all as Bill, died on April 20th at the age of 85. Guy will be best remembered as the leading proponent of the use of specific absorption rates (SARs) as a way of measuring the radiation dose associated with RF/MW exposure.

Guy received a doctorate in electrical engineering in 1966 from the University of Washington, Seattle, and then joined the UW faculty where he remained until his retirement in 1991. He stayed active as a consultant over the next 15 years. He served as a prominent...

EirGrid, the Irish state-owned power line company, is planning to build three new 400 kV lines and to upgrade 2,000 km of existing power lines at a cost of €3.2 billion to help provide reliable service in the years to come. But there's nothing new about its approach to addressing the public's concerns about EMFs.

Take a look at this new 35-minute “Prime Time” video from RTÉ, a local TV station. It illustrates, once again, the double talk endemic to...

The research group at the University of Oxford that reported a link between long-term use of a mobile phone and an elevated risk of acoustic neuroma (AN) in May now says that it is no longer there. In a short letter to the International Journal of Epidemiology (IJE), the Oxford team advises that when the analysis was repeated with data from 2009-2011, "there is no longer a significant...
