brain tumors: Microwave News Article Archive (2004 - )

The incidence of brain tumors in Australia did not increase between 2003 and 2013, according to a new analysis by the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) and the Australian Centre for Electromagnetic Bioeffects Research (ACEBR). This means that there can be no link between the use of mobile phones and brain cancer, they claim. 

If such an association were true, “then the brain tumor rates would be higher than those that are observed,” states an ARPANSA press release that accompanies the new paper published in BMJ Open.

“People say mobile phones can cause cancer but our study showed this was not the case,” said ARPANSA’s Ken Karipidis, the lead author.

Others are skeptical. The work is incomplete and misleading —or worse, they say.

A U.K. epidemiologist has confirmed that glioblastoma (GBM), the most aggressive type of brain tumor, is on the rise in England. In a new paper, Frank de Vocht of the University of Bristol reports that he sees a significant and consistent increase in GBM in the frontal and temporal lobes of the brain over the last 20-30 years.

Alasdair Philips, an independent researcher based in Scotland, and three colleagues first documented the increase last March. It was not due to improved diagnosis, they said, but they could not pinpoint which “environmental or lifestyle factor” was responsible. There was one obvious possibility: cell phones.

The incidence of glioblastoma multiforme (GBM), the deadliest type of brain tumor, more than doubled in England between 1995 and 2015, according to a new analysis of national statistics. During that time, the number of cases of GBM rose from 983 to 2,531.

“We found a sustained and highly significant increase in GBM throughout the 21 years and across all ages,” said Alasdair Philips, the lead author of the study, which has just been released online by the peer-reviewed, open access, Journal of Environmental and Public Health.

“The incidence rate of GBM, the most aggressive and quickly fatal brain tumor, is rising dramatically in England while the rates for lower grade tumors have decreased, masking this dramatic trend in the overall data,” Philips told Microwave News from his home in Beeswing in southern Scotland, not far from the English border.

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.
