The Japanese/Korean partial repeat of the U.S. National Toxicology Project’s (NTP) RF–animal cancer study has been hit by delays. The project is two years behind schedule, with results now not expected before the middle of next year.

“We hope we will present our data” next summer at the BioEM 2026 conference in Australia, Professor Katsumi Imaida of Kagawa University, the leader of the Japanese team, told Microwave News via email. The international NTP validation project —nicknamed “NTP Lite”— is in its “final stages,” he wrote.

The project was launched in 2019 to confirm or counter the $30+ million NTP animal study, which showed “clear evidence” that RF radiation can cause cancer in rats.

An advisory group to the International Agency for Research on Cancer (IARC) has —once again— recommended a new assessment of the cancer risk posed by RF radiation. RF is one of about a hundred agents listed as “high priority” for evaluation over the next five years, 2025-2029.

The panel, made up of 28 independent scientists from 22 countries, met last month in Lyon, France (IARC’s hometown), to consider more than 200 agents that had been nominated for evaluation or reevaluation. The panel’s recommendations were announced yesterday in the news section of Lancet Oncology and an IARC press release.

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.
