A Report on Non-Ionizing Radiation

Hans Skovgaard Poulsen sounded the alarm seven years ago. There’s a spike in glioblastoma —GBM— in Denmark, he warned. Poulsen, the head of neuro-oncology at Copenhagen University Hospital, called it “frightening.”

On November 2, 2012, the Danish Cancer Society dutifully sent out a press advisory under the title “...

“Occupational Exposure to ELF Magnetic Fields and Risk for Central Nervous System Disease: An Update of the Danish Cohort Study Among Utility Workers,” International Archives of Occupational and Environmental Health, online April 20, 2017.

“We observed elevated risks of dementia, motor neurone disease, multiple sclerosis and epilepsy and lower risks of Parkinson disease in relation to exposure to ELF-MF in a large cohort of utility employees.”

Freaky or What?

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...

Something Is Rotten in Denmark

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.

Spike in “Aggressive” Brain Cancer in Denmark

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...

The Danish Cohort Study:The Politics and Economics of Bias

The latest update of the Danish cell phone-cancer study is being touted as the biggest and best ever. It shows “no link between mobile phone use and [brain] tumors,” according to the press release.

Don’t believe a word of it.

On October 20, the British Medical Journal released the third installment of the Danish Cancer Society’s cohort study, which has been tracking some 400,000 mobile phones subscribers since the 1980s. The whole enterprise has been dogged by controversy and political suspicions since the first results were published ten years ago.

No Risk of Eye Cancer

Cell phones do not increase the risk of developing eye cancer, at least for the first ten years of use, according to a group of German researchers led by Andreas Stang at the Martin-Luther-University of Halle-Wittenberg in Halle. This marks a reversal. Eight years ago, Stang reported a possible association in a smaller and less detailed study (see MWN, J/F01, p.9).

WHO Welcomes Electric Utility Industry To Key EMF Meeting, Bars the Press

The week of October 3 in Geneva, the World Health Organization (WHO) will set its recommendations for public exposures to power-frequency electromagnetic fields (EMFs).

A 20-member task group from 17 countries, assembled by Michael Repacholi, the head of the WHO EMF project, will finalize an Environmental Health Criteria (EHC) document, which is designed to guide the development of standards for extremely low frequency (ELF) EMFs all over the world. It will likely represent WHO’s official position on EMF health risks for years to come.

Can RF Protect Against Cancer?

Could cell phone radiation actually protect against brain cancer? Could it provide “vitamins for the brain”, as one irreverent epidemiologist suggested recently? Such a possibility, however improbable, is not as far fetched as it may sound.

Danes See No Link to Acoustic Neuroma

Danish researchers have found no support for Lennart Hardell and Kjell Hansson Mild’s contention that mobile phones increase the risk of acoustic neuromas. A team led by Christoffer Johansen of the Danish Cancer Society in Copenhagen compared the histories of 106 cases of acoustic neuromas, benign tumors of the cranial nerve, with those of 212 controls. There was no elevated rate of cancer, even among those who had used a cell phone for ten years or more.
