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.

“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.

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.

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.

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.

Ron Melnick, formerly with NTP, spells out 15 “extensive and misleading” statements made by ICNIRP on the NTP and Ramazzini cell phone–animal studies. Also today, Ramazzini’s Fiorella Belpoggi  posted her comments. See also Melnick’s commentary on the NTP study posted (...

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...

“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.

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.

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.

Here are four key takeaways from the NTP press conference held this afternoon, soon after the release of its two cell phone reports:

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...

The NTP has released two reports on the cancer risks from cell phone radiation (GSM and CDMA) on rats and mice. They are available here.

The NTP press release, “High Exposure to RF Radiation Linked to Tumor Activity in Male Rats” is here.

The National Toxicology Program (NTP) has announced that the draft reports...

“Considering (a) the conflicting results of RF epidemiology studies and (b) the lack of generally accepted biophysical or molecular mechanisms through which RF could induce or promote neoplasia, data from animal bioassays will play a central role in ‘weight-of-the-evidence’ assessments of the possible health effects of RF exposure.” Abstract only. By IITRI’s David McCormick, who ran the exposures for the NTP–cell phone cancer study.

The National Toxicology Program (NTP) will release the “complete results” of its $25 million project on cell phone cancer risks early next year, according to a statement posted on its Web site yesterday.

“The complete results from all the rats and mice studies will be available for peer review and public comment by early 2018,” the NTP states. The animals were exposed to GSM or CDMA radiation for two years before they were sacrificed...

March 21, 2017

The National Toxicology Program (NTP) has changed course and will not —at least for the time being— publish its findings of increased DNA breaks among rats exposed to cell phone radiation as a stand-alone paper.

The DNA study, which is part of NTP’s landmark experiment showing that RF radiation can lead to tumors in the brains and hearts of laboratory animals, will now be incorporated in NTP’s Technical Report on the $25 million project, the NTP has told Microwave News.

From China. The third recent meta-analysis that points to a cancer risk. Here are links to all three.

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...

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

Geoffrey Kabat offers a remarkably apt critique of his own writings with his answer to the question, “Do Cell Phones Cause Brain Cancer?”:

“The problem with research in this area is not that it is worthless but that all too frequently it is interpreted naively and uncritically and used for partisan rather than scientific purposes.”

That’s from his new book, Getting Risk Right. It may be the only thing he gets right in the whole book. Hard to say because after reading the chapter on cell phone radiation, we couldn’t slog on much further.
