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...

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.

In May, the U.S. National Toxicology Program (NTP) announced that male rats exposed to cell phone radiation developed higher rates of cancer. Soon, the NTP will explain how that might have happened.

The same RF/microwave radiation that led male rats to develop brain tumors also caused DNA breaks in their brains. Female rats —which did not have significant elevated tumor counts— had fewer DNA breaks.

All these findings are part of the same $25 million NTP project.

The NTP results provide “strong evidence for the genotoxicity of cell phone radiation,” Ron Melnick told Microwave News.

Also here. Mostly Michael Wyde’s talk with important comments by NTP Director Linda Birnbaum and Associate Director John Bucher. Birnbaum calls the link between RF and Schwannomas of the heart “unequivocally clear” (@43:20-minute mark). A few minutes later, she describes it as having a “beautiful dose-relationship.” Bucher talks about the continuity in the spectrum between hyperplasia and glioma.

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.

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...

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 26, 2016

This evening, the National Toxicology Program (NTP) released a draft of the report on its two-year cell phone cancer study. Linda Birnbaum, the director of the NIEHS, and John Bucher, the leader of the study, will present the report at a teleconference tomorrow, Friday. They are the director and associate director of the NTP, respectively. [Birnbaum did not...

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.

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.

March 13, 2015

The RF–cancer story took a remarkable turn a few days ago. A new animal study challenged many of the assumptions which lie at the heart of claims that RF radiation —whether from cell phones, cell towers or Wi-Fi— are safe.

The new study, from Germany, a replication of an earlier experiment, also from Germany, found that weak cell phone signals can promote the growth of tumors in mice. It used radiation levels that do not cause heating and are well below current safety standards. Complicating matters even further, lower doses were often found to be more effective tumor promoters than higher levels; in effect, turning the conventional concept of a linear dose-response on its head.

PERFORM-A is a washout. The eight-year, $10 million industry research project that was supposed to answer the question, "Does cellphone radiation cause cancer in animals?" instead promises to sow more confusion and mistrust.

July 30, 2004

The National Institute of Environmental Health Sciences (NIEHS) is negotiating a sole source contract with the IIT Research Institute (IITRI) in Chicago to run the National Toxicology Program’s (NTP) RF–animal studies. The studies will cost in excess of $10 million. The NIEHS requested proposals last February, but no one responded.

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.
