UPDATE 3
A new group of IARC advisors is meeting in Lyon this week to set priority agents for the agency to review in 2025-2029. More here.

January 19, 2024
UPDATE 2
IARC has announced that the agency will evaluate the cancer risks of “automotive gasoline and some oxygenated additives” from February 25 to March 4, 2025. The reassesssment of RF radiation will have to wait.

October 25, 2023
UPDATE 1
Other Monograph meetings have now been scheduled for March, June and November 2024. The next possible slot for RF radiation is in early 2025.

December 12, 2022

On November 23, 2002, Elisabete Weiderpass, the Director of the International Agency for Research on Cancer (IARC), revealed that a new assessment of the evidence linking radiofrequency (RF) radiation to cancer would likely take place in early 2024. A formal decision could come within a few months.

Calls for a new IARC evaluation have been mounting for some years following the release of two large animal studies showing elevated tumor counts after lifelong exposure to RF radiation.

March 14, 2024

The International Commission on the Biological Effects of Electromagnetic Fields (ICBE-EMF) has written to Italian government officials to support the country’s strict 6 V/m RF exposure limit.

The letter, dated March 13, expresses “great concern” that the standard might be weakened. It is signed by Ronald Melnick, the chair of ICBE-EMF, and by Elizabeth Kelley, its managing director.

November 1, 2022

An international group of research scientists has come together to challenge ICNIRP, the International Commission on Non-Ionizing Radiation Protection.

The new panel wants a complete revision of ICNIRP’s guidelines for exposures to radiofrequency (RF) radiation. The researchers are demanding the adoption of more scientifically rigorous standards, which better protect public health and the environment.

“We are calling for an independent evaluation of the limits,” said Joel Moskowitz of Berkeley Public Health.

Senior environmental health scientists are calling for JAMA Oncology to retract a review of RF radiation and cancer by David Robert Grimes, a physicist at Dublin City University.*

Grimes’s paper, which was posted on the journal’s website on December 9th, has prompted a barrage of letters of protest to Nora Disis, the editor of JAMA Oncology.

Among those calling for retraction is Linda Birnbaum, who, for ten years, 2009-2019, was the director of the National Institute of Environmental Health Sciences (NIEHS) and the National Toxicology Program (NTP). Ronald Melnick, who led the team that designed the NTP RF–cancer study, is another harsh critic.

September 17, 2019

The U.S. National Toxicology Program (NTP) will soon embark on a new phase of its long-running RF project. Last year, the NTP concluded that RF radiation causes cancer; now it will begin a systematic search for mechanisms to explain how and why the tumors developed. Work is expected to begin by the end of the year.

The research plan is wide-ranging. It will include studies on gene expression, oxidative stress and DNA damage and repair, as well as on the possible role played by heat. Other priorities on the NTP agenda are studies on behavior and stress.

“Critique of the ICNIRP Note of September 4, 2018, Regarding Recent Animal Carcinogenesis Studies,” Ron Melnick, September 12, 2018.

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 (Sept 20) by Environmental Research.

April 9, 2018

“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.

December 1, 2017

”A few days ago, I received an urgent warning from a longtime contact in Sweden. An industry associate had told him that the U.S. National Toxicology Program’s study on cell phone cancer risks was screwed up and essentially “useless.”

I was tempted to disregard it as nothing more than a corporate delusion. But the original source was said to be Maria Feychting, a professor at the Karolinska Institute and the vice chair of the International Commission on Non-Ionizing Radiation Protection (ICNIRP). She had cast doubt on the landmark $25 million NTP RF–animal study in a talk presented at the Royal Swedish Academy of Sciences —the institute that awards the Nobel prizes in physics and chemistry every year.

I decided I had to check out the rumor.

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.

June 10, 2016

On May 31, the New York Times ran a piece in what it calls “The Upshot” on the National Toxicology Program’s (NTP) cell phone animal study. The column is a regular feature in the Times that seeks to give readers context for stories in the news. This one was titled “Why It’s Not Time to Panic About Cell Phones and Cancer.” It was written by Aaron Carroll, a pediatrician at the Indiana University School of Medicine.

Carroll outlined reasons for his skepticism over the cancer results, calling the $25 million NTP study “imperfect.” This prompted a response from Ron Melnick, who led the study’s design team before he retired in 2009. In an eight-point rebuttal, Melnick corrected what he called “numerous and misleading statements.” The full text of his letter is reprinted below.

June 1, 2016

One common criticism of the new NTP cell phone cancer study is that, unlike the male rats, there was no significant increase in tumors among female rats.

For instance in its latest assault on the NTP results, the New York Times is running a comment by a pediatrics professor in Indiana, in which he states:

“It’s also odd that...

May 31, 2016

Senior managers at the National Toxicology Program (NTP) released the preliminary results of their cell phone radiation study late last week. They were so concerned about the elevated rates of two types of cancer among exposed rats that they felt an immediate public alert was warranted. They considered it unwise to wait for the results to wend their way into a journal sometime next year. Not surprisingly, the NTP report generated worldwide media attention.

There were some startling reactions. Both the American Cancer Society (ACS) and Consumer Reports immediately shelved their long-held, wait-and-see positions. In a statement issued soon after the NTP’s press conference, Otis Brawley, ACS’ chief medical officer, called the NTP report “good science.” Consumer Reports said that the new study was “groundbreaking” and encouraged people to take simple precautions to limit their exposures.

However, much of the mainstream media saw it very differently. The Washington Post ran its story under the headline, “Do Cell Phones Cause Cancer? Don’t Believe the Hype.”

May 25, 2016

The cell phone cancer controversy will never be the same again.

The U.S. National Toxicology Program (NTP) is expected to issue a public announcement that cell phone radiation presents a cancer risk for humans. The move comes soon after its recently completed study showed statistically significant increases in cancer among rats that had been exposed to GSM or CDMA signals for two-years.

Discussions are currently underway among federal agencies on how to inform the public about the new findings. NTP senior managers believe that these results should be released as soon as possible because just about everyone is exposed to wireless radiation all the time and therefore everyone is potentially at risk.

November 30, 2015

NIEHS really doesn’t want to talk about it. Ten years into a $25+ million project to assess the cancer risk of wireless radiation in laboratory animals, the staff at the National Institute of Environmental Health Sciences remains tight-lipped and refuses to release project documents.

NIEHS has many reasons for keeping a low profile. The RF project, the most expensive in National Toxicology Program history, is years late and two-to-three times over budget. A more immediate concern is that it could force the institute into a position it would desperately prefer to avoid: Being at the center of the ever-contentious controversy over cell phone radiation and cancer.

June 3, 2011

It's not easy to reach unanimous agreement on anything to do with cell phone radiation. And when it comes to cell phones and cancer, forget about it. But the International Agency for Research on Cancer (IARC) nearly pulled it off. On Tuesday, May 31, more than two dozen scientists and doctors from 14 countries —a group IARC Director Christopher Wild called “the world’s leading experts”— issued a joint statement that cell phone and other types of radiofrequency (RF) and microwave radiation might cause cancer.

January 18, 2010

Lorenzo Tomatis got it. But few others do. Among those who don’t are the many managers at the National Institute of Environmental Health Sciences (NIEHS) who refuse to allow that the EMF–cancer playbook may be different from the one for chemicals. Even now, when there is ample evidence that power line EMFs can increase the risk of childhood leukemia and there is a growing suspicion that cell phone radiation is associated with three different types of tumors, NIEHS prefers to look the other way. The institute has long resisted endorsing precautionary policies for any kind of EMFs.

June 10, 2004

The U.S. National Toxicology Program (NTP) was ready to spend some $10 million on RF research, but no one wanted it. In February, the NTP issued a request for proposals to carry out a number of animal studies on the possible cancer risks associated with wireless communications. Not a single lab responded by the April 8 deadline.
