GBM Incidence Rates Relatively Steady in U.S. and Canada

The incidence of glioblastoma multiforme, GBM, the most aggressive type of brain tumor, though rising slowly over the last 20 years, has not jumped up in the U.S. and Canada, as it has in England and a number of other northern European countries, according to a new analysis of national brain tumor registry data.

Between 1995 and 2015, GBM rates went up 10% in the U.S. and 26% in Canada. In contrast, the increase in England over the same period was 110%.

GBM Rising in Denmark,Much as in England

GBM is going up in Denmark. The steady rise is very similar to what has been seen in England.

New government data, released in May by a member of the Danish Parliament, show a near doubling of this fatal brain tumor, glioblastoma multiforme, since the year 2000. You can see the trend by following the orange line in the histogram …

Colorectal Cancer Soaring in Young Adults; Are Smartphones in the Mix?

De-Kun Li wants to change the conversation on cell phones and cancer. Li, a senior epidemiologist and veteran EMF researcher, believes that brain tumors have been getting too much attention at the expense of other types of cancer, notably colorectal cancer.

Efforts to reduce colon and rectal cancers have been a striking success story for those over 50 years old. Incidence among older Americans declined 32% between 2000 and 2013, due largely to better screening. But the story for young adults is very different. Those born around 1990 now face four times the risk of developing rectal cancer and twice the risk of colon cancer in their 20s, compared to those born around 1950, according to the American Cancer Society.

“No one can explain this apparent contradiction,” Li told Microwave News. Known risk factors for colorectal cancer include obesity, an unhealthy diet and lack of physical activity, but Li doesn’t think they can resolve the paradox.

The Precarious Case Against Precaution

It has been nearly eight years since an expert panel of the International Agency for Research on Cancer (IARC) classified RF radiation as a possible human carcinogen. Since then, neither the World Health Organization (WHO) nor the International Commission on Non-Ionizing Radiation Protection (ICNIRP) has recommended precautionary policies to limit potential health risks.

No U.S. health agency has yet advised the public to reduce RF exposures.

Even after two large animal studies —by the U.S. National Toxicology Program (NTP) and Italy’s Ramazzini Institute— presented clear evidence of a cancer link last year, the WHO has remained silent; ICNIRP responded by calling both animal studies unconvincing.

Now comes the Annual Review of Public Health, which on January 11 posted a paper by five leading epidemiologists who posit that, after a systematic review of all the human studies, they don’t see an elevated cancer risk. The takeaway is that the IARC classification was a mistake.

Row over Cancer, Cell Phone Review

A major review of cell phone cancer risks is at the center of an ongoing controversy over whether it is biased and should be withdrawn.

The new paper by some of the most prominent members of the RF–health community contends that epidemiological studies do not show an increased risk of brain tumors or acoustic neuroma associated with the use of mobile phones. That is, cell phones are cancer safe.

Aussies Claim No Brain Tumor Link; Skepticism Abounds

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.

How NTP Controlled Coverageof Cell Phone Cancer Story

Much of the press coverage of the final NTP cell phone/cancer report was lousy. This time, the NTP seems to have wanted it that way.

Reporters were given very little notice to join the NTP teleconference on the release of the report. Nor was there much time to prepare a story for publication.

I received an email at 10:45 am on October 31 for a teleconference at 2 pm that same day. Many reporters missed the advisory and the call. Editors had little time to assign the story.

Attendance on the teleconference was spotty.

Cell Phone Radiation Leads to Cancer, Says U.S. NTP in Final Report

“We believe that the link between radiofrequency (RF) radiation and tumors in male rats is real,” says John Bucher, the former associate director of the U.S. National Toxicology Program (NTP).

The announcement accompanies this morning’s release of the NTP final reports of studies on cancer in rats and mice exposed to cell phone radiation. Bucher’s project, the largest in NTP history, cost $30 million and took more than ten years to complete.

The NTP found what it calls “clear evidence” that two different types of cell phone signals, GSM and CDMA, increased the incidence of malignant tumors in the hearts of male rats over the course of the two-year study.

Location, Location, LocationAggressive Brain Tumors Tell a Story

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.

Japan and Korea Planning Their Own Cell Phone Animal Studies

Japanese and Korean officials are working on a partial replication of the U.S. National Toxicology Program (NTP) animal study on cancer risks from cell phone radiation. The project is expected to be approved and get underway late next year.

Though collaborating on a common experimental design, each country will carry out its own exposures with animals from the same breeder. If the designs are similar enough, the two sets of data will be combined in a joint analysis.

“We have been discussing this issue in Japan,” said Masao Taki of the Department of Electrical and Electronic Engineering at Tokyo Metropolitan University, who was a member of ICNIRP from 1996 to 2008.

“Analyses of Temporal and Spatial Patterns of GBM and other Brain Cancers Subtypes in Relation to Mobile Phones Using Synthetic Counterfactuals,” Environmental Research, posted October 17, 2018.

Frank de Vocht confirms that GBM is rising in the U.K. but argues that it’s “unlikely” that RF from cell phones is responsible.

ICNIRP Finds NTP & Ramazzini RF–Animal Studies Unconvincing

The International Commission on Non-Ionizing Radiation Protection (ICNIRP) has determined that the two recent animal studies pointing to a cancer risk from cell phone radiation are not convincing and should not be used to revise current exposure standards.

In a “note” published today, the 12-member group states that the studies by the National Toxicology Program (NTP) and the...

“Clear Evidence” of Cell Phone Cancer Risk, Say Leading Pathologists

“You had it right the first time.” That was the implicit message to the National Toxicology Program (NTP) from an expert panel after a point-by-point review of NTP’s draft reports on its $25 million study of cancer risks of cell phone radiation in mice and rats.

Two years ago, with the results in hand, the NTP rushed to warn the public about the dangers of cell phones. It issued an interim report pointing to higher rates of tumors in the hearts and brains of male rats exposed to two different kinds of phone radiation. Then early this February with the release of the formal draft reports, the NTP made a U-turn, saying that using a cell phone “is not a high-risk situation.”

Now a peer review panel —11 pathologists and toxicologists from academia and industry and one statistician— has concluded that there is “clear evidence of carcinogenic activity” in those male rats.

Aggressive Brain Tumors on the Rise in England

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.

What Changed at NTP?

Why was the NTP so ambivalent about its cell phone cancer findings at the press conference last Friday when two years ago the same scientific evidence prompted a public health warning?

Some of the pathology numbers got tweaked since they were first released in 2016, but the changes were minor. It’s the same data set —but with a very different interpretation. The NTP mindset somehow shifted from we need to release this important new health data now to this is “not a high-risk situation.”

Who or what moved the NTP managers to change their outlook? There’s no shortage of suspects and suspicions.

Cell Phone Use Is “Not a High-Risk Situation”

Here are four key takeaways from the NTP press conference held this afternoon, soon after the release of its two cell phone reports [these are no longer available]:

1. NTP’s bottom line on cell phone use: “This is not a high-risk situation.”

2. RF radiation has biological effects at levels previously believed to be innocuous —they may be good or bad.

3. NTP will continue to do RF health studies. A new exposure facility is being built on the NIEHS campus, which will be smaller and more flexible than the one used...
