“There was no clear evidence for interactions between occupational ELF and chemical exposures in relation to glioma or meningioma risk observed.” For more on INTEROCC, go here.

“An increased risk in late stage (promotion/progression) of astrocytoma grade IV for occupational ELF-EMF exposure was found.” From Sweden (including Lennart Hardell). For background, see our “EMF Cancer Promotion: An Old Idea Makes a Strong Comeback.”

The incidence of glioblastoma multiforme (GBM), the most virulent and deadly type of brain cancer, is going up in the U.K., while the incidence there of other types of malignant brain tumors are declining, according to some newly published raw data.

Take a look at the two plots below and the trends are immediately apparent.

The incidence rates are not corrected for age, or...

Novocure’s 200 kHz signals kept 43% of GBM patients alive compared to 30% on the standard treatment.

Senior managers at the National Toxicology Program (NTP) released the preliminary results of their cell phone radiation study late last week. They were so concerned about the elevated rates of two types of cancer among exposed rats that they felt an immediate public alert was warranted. They considered it unwise to wait for the results to wend their way into a journal sometime next year. Not surprisingly, the NTP report generated worldwide media attention.

There were some startling reactions. Both the American Cancer Society (ACS) and Consumers Reports immediately shelved their long-held, wait-and-see positions. In a statement issued soon after the NTP’s press conference, Otis Brawley, ACS’ chief medical officer, called the NTP report “good science.” Consumer Reports said that the new study was “groundbreaking” and encouraged people to take simple precautions to limit their exposures.

However, much of the mainstream media saw it very differently. The Washington Post ran its story under the headline, “Do Cell Phones Cause Cancer? Don’t Believe the Hype.”

The latest on NovoCure’s EM therapy for brain tumors. Not a cure; it increases overall survival time by about three months. The cost is high: $21,000/month. See also our other stories about NovoCure going back to 2007.

Those who first used wireless phones before the age of 20 have a higher brain tumor risk and a shorter survival time, Hardell told us. This paper, along with others like a recent German-Iranian paper, call for an “urgent revision of current exposure guidelines,” they write. Open access.

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...

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 our study, we found an increased risk in those subjects reporting a prolonged use, making numerous calls, whose use was especially occupational and more often in urban areas…” For ≥ 986 h of life-long use, OR=2.89, 95% CI: 1.41-5.93 for gliomas; OR=2.57, 95% CI: 1.02-6.44 for meningiomas; for ≥18,360 calls, OR=2.10, 95% CI: 1.03-4.31 for gliomas. (All these elevated risks are statistically significant.) From Bordeaux University Segalen, France.

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.

“For lung, breast and brain cancer, we found no evidence of an association.…We did observe associations between ELF-EMF exposure and follicular lymphoma and acute myeloid leukemia in men although AML did not show clear exposure-response relationship.” From the Institute for Risk Assessment Sciences at Utrecht University.

September 26, 2013

“We show a clear association between national penetration of cellular telecommunications subscriptions and higher incidence of brain and nervous system cancers, with a latency between exposure and clinical onset of at least 11–12 years, but probably more than 20 years.”

Using a new data set covering 2007-2009, Lennart Hardell and his research team have reaffirmed their previous findings that long-term use of a wireless phone leads to higher rates of both malignant brain tumors and acoustic neuromas (AN), but not of meningiomas, a type of benign brain tumor. In general, they report, the longer the use, the greater the risk for AN and malignant brain tumors.

All three new papers are open access. For the malignant brain tumor paper, click here; for the AN paper...

A new study from the U.K. is adding support to the still controversial proposition that long-term use of a cell phone increases the risk of developing acoustic neuroma, a tumor of the auditory nerve. No higher risk of glioma or meningioma, two types of brain cancer, was observed.

Women who used a mobile phone for more than ten years were two-and-half-times more likely to have an acoustic neuroma than those who never used a phone. The finding is statistically significant. This is the fourth epidemiological study that shows an association between long-term use of a cell phone and acoustic neuroma.

November 8, 2012

The Danish Cancer Society is reporting that the number of men diagnosed with glioblastoma —the most malignant type of brain cancer— has nearly doubled over the last ten years. Hans Skovgaard Poulsen, the head of neuro-oncology at Copenhagen University Hospital, is calling it a "frightening development...
