“Occupational Exposure to High-Frequency EMFs and Brain Tumor Risk in the INTEROCC Study: An Individualized Assessment Approach,” Environment International, online July 31, 2018.

“In conclusion, despite the improved quantitative exposure assessment used in this study, the results do not support a positive association between occupational exposure to high-frequency EMF and either glioma or meningioma risk. However, given our limited statistical power, due to the small number of exposed participants, and despite our results’ lack of significance our findings foster the need for further research focusing on RF magnetic fields and tumor promotion, as well as possible interactions with other frequencies and with chemicals.” (see press release.)

“Interactions Between Occupational Exposure to ELF Magnetic Fields and Chemicals for Brain Tumour Risk in the INTEROCC Study,” Occupational & Environmental Medicine, posted June 9, 2017.

“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.

“Investigation of Bias Related to Differences Between Case and Control Interview Dates in Five Interphone Countries,” Annals of Epidemiology, December 2016.

This new analysis found “generally similar results” to the original Interphone study, but with “stronger positive associations among long-term users.”

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 battle over Interphone continues. This time it's in full public view as key players publish papers detailing where they stand on cell phone tumor risks. There haven't been any big surprises since their opinions have long been known. Yet, the diametrically opposing views have led to conflicting stories in the media as each new study is released.

"[I]ndications of an increased risk in high- and long-term users [of cell phones] from Interphone and other studies are of concern." This is the conclusion of a commentary, published yesterday in Occupational Environmental Medicine by Elisabeth Cardis and Siegal Sadetzki. Cardis is the head of the ...

It's only a short letter buried in the back pages of a journal, but it could change the entire cell phone–cancer controversy.

A group at Hebrew University in Jerusalem has reported a sharp increase in the incidence of parotid gland tumors in Israel over the last 30 years. Rakefet Czerninski, Avi Zini and Harold Sgan-Cohen found that these tumors have quadrupled since 1970, "with the steepest increase" after 2001 (see plot below). Their letter appears in the January 2011 issue of Epidemiology; it's a free download. They are with the Hadassah School of Dental Medicine at the university.

There’s an old saying that a camel is a horse designed by a committee. Welcome to Interphone.

The good news is that the Interphone paper has finally been made public after a four-year stalemate within the 13-country research team. But it comes at a price. A series of compromises over how to interpret the results of the largest and most expensive study of cell phones and brain tumors ever attempted has left the paper with no clear conclusions other than more research is needed.

Senator Arlen Specter (D-PA) will hold a hearing on cell phones and health on September 14. So says Devra Davis, an activist scientist at the University of Pittsburgh. If Specter follows through, it would be the centerpiece of a conference she is organizing that week in Washington, as well as a triumph for Davis herself. She is on a mission to make cell phones a more visible public health issue in the U.S. and to secure funding for a major research program. It would be the first time in more than 30 years that the U.S. Senate has addressed RF/microwave health risks.

The stalemate over Interphone is coming to an end. A project of the International Agency for Research on Cancer (IARC) on the possible links between mobile phones and tumors, Interphone has been bogged down for over three years while its members feuded over how to interpret their results. Now, Microwave News has learned, a paper on brain tumor risks is about to be submitted for publication. Christopher Wild, the director of IARC, forced a compromise to resolve what had become a major embarrassment for the agency.

Some news notes on the Interphone study:

• Those who say there are no long-term cell phone risks often point to the Interphone study from Japan, published earlier this year, for support. As we have previously reported, the Japanese researchers said there was no association between cell phones and brain tumors, even though they found a close to sixfold increase in glioma among heavily-exposed users after ten or more years (see our February 15 post). That link was based on a small number of cases and was not statistically significant; the Japanese attributed the increase to recall bias. Bruce Hocking, an occupational and environmental health physician in Melbourne, Australia, suggests otherwise. In a letter published this week in the British Journal of Cancer, Hocking points out that the risk of meningioma (another type of brain tumor) is hardly raised at all (OR=1.14). He writes: "If recall bias is the true explanation for the increased risk of glioma, it should similarly have affected the meningioma group, but it has not. Therefore, the increased risk in the glioma group may be a true finding."

April 28, 2008

Another Interphone researcher is expressing concern over the tumor risks associated with the long-term use of mobile phones. "I think the evidence that is accumulating is pointing towards an effect of mobile phones on tumors," Professor Bruce Armstrong of the University of Sydney School of Public Health told "TodayTonight," an Australian current affairs show on Channel 7, a national network.
