A Report on Non-Ionizing Radiation

Thyroid cancer among women is skyrocketing all over the world. Incidence is growing faster than for any other cancer. This has been going on for a long time, and the reasons why remain elusive.

The prevailing view is that there’s been an “epidemic of diagnosis” —that is, overdiagnosis— particularly following a screening program. The tumors have always been there, the argument goes, but new and better detection tools (ultrasound, for example) have made it easier to spot small ones, many of which would likely never present a real threat. In any case, thyroid cancer is not one of the bad ones; 98-99 percent of those diagnosed survive at least five years, the highest for all cancers. Watchful waiting is often the best prescription.

The only recognized cause for thyroid cancer is ionizing radiation.

Last January, a team led by Yawei Zhang of the Yale School of Public Health in New Haven published an epidemiological study on the possible link between thyroid cancer and cell phones. Though some “suggestive” associations were seen among long-term users, none was statistically significant. Still, the results “warrant further investigation,” they advised.

Zhang did follow up, and what she found could well change the way people think about cell phone cancer risks.

She discovered that some people have an innate susceptibility to thyroid cancer when exposed to cell phone radiation. These individuals have small variations in their DNA which affect the functioning of seven different genes.

All seven genes regulate DNA repair.

This could be a breakthrough, a major breakthrough. It could explain how power lines promote childhood leukemia. It could identify which children are at greatest risk. And it could shed new light on the pivotal role played by EMF-induced DNA breaks.

Chinese researchers have found that children who carry a defective version of a gene that would otherwise help repair damaged DNA are much more likely to develop leukemia if they also live near power lines or transformers. Xiaoming Shen and coworkers at the Jiao Tong University School of Medicine in Shanghai have reported that children with this genetic variant —known as a polymorphism or snp (pronounced "snip") —and who lived within 100 meters of these sources of EMFs had over four times more leukemia than neighboring children with a fully functional version of the same gene.

It's long been known that children with Down's syndrome have a much greater chance of developing acute leukemia —up to 20 times greater or even higher. Now, in the first study of its kind, a group of Mexican researchers have shown that Down's children exposed to magnetic fields of 6 mG (0.6 µT) or more had close to four times the risk of developing acute leukemia compared to other Down's children. (The analysis was based on spot measurements, rather than the more commonly used 24-hour readings.) Writing in the January 2007 issue of Epidemiology, Juan Mejia-Arangure and coworkers conclude that genetic susceptibility to leukemia may well modify the effects of EMFs.

Wolfgang Löscher has suffered numerous personal attacks for his work on EMFs and breast cancer. But he struggled on, and now he may have resolved a fundamental problem in EMF research: Why different labs doing what appear to be identical experiments, produce conflicting results.
