Dr. Len over at the American Cancer Society is raising legitimate questions about the early release of findings by the World Health Organization’s International Agency for Research on Cancer (IARC) that cell phone use may increase the risk of brain cancer (hat tip to Gary Schwitzer’s HealthNewsReview). The actual study — drawn from an analysis of “hundreds of scientific articles ” — won’t be published in Lancet Oncology “for a few days,” according to IARC. Says Dr. Len:
Unfortunately, drawing broad and sweeping conclusions based on a press release and a news conference leaves many of us wondering just what the evidence shows that led to the conclusion announced today that “radiofrequency electromagnetic fields” may be possibly cause cancer in people.
The evidence, when it appears, will be murky. A few years ago, I spent several months reviewing some of the evidence in this troubling field, largely from a conflict-of-interest perspective. The global telecommunications industry funds much of the science. Even when government agencies fund research, the results are difficult to interpret. The studies invariably involve looking for a very small number of negative health outcomes (brain cancers) in very large populations. Two researchers, looking at the very same set of epidemiological facts, will often come to different conclusions. And, as often as not, those conclusions correlate with whether the the researchers are independent or whether they are on industry’s payroll.Continue reading…
