IARC: Microwave News Article Archive (2004 - )

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.

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.

Partial results of the Ramazzini Institute’s RF–animal study, which show a statistically significant increase in tumors in the hearts of male rats exposed to GSM radiation, were officially released today. They appear in Environmental Research, a peer-reviewed journal.

As we reported last month, the Ramazzini finding of Schwann cell tumors —called schwannomas— in the rat hearts is consistent with a similar finding by the U.S. National Toxicology Program (NTP) in a $25 million RF project.

In an interview with Microwave News, Fiorella Belpoggi, the senior author of the new paper and the director of the Ramazzini Institute’s Research Center in Bologna, Italy, offered her views on the new results, the parallels with those of the NTP and the implications for IARC’s designation of the cancer risk of RF radiation.

IARC has closed the book on the Interphone project, its study of mobile phone tumor risks. A couple of days ago, the cancer agency quietly issued a final report, stating that its work "has now been formally completed." The report, though dated October 3, 2011, was released on March 16th.
