Despite What Robert F. Kennedy Wants You To Think, Cell Phones Do Not Cause Brain Cancer
“numerous studies going back to the year 2000 all indicate there is no particular reason to fear cell phones as a cause of cancer, and a new paper by Li Zhang and Joshua Muscat of the Department of Public Health Sciences at Pennsylvania State University examines the most up-to-date data from the United States to examine this question as if for the first time.
Most studies on this question so far have been case-control studies. This type of study is subject to biases (information bias and selection bias) because it selects subjects who already have the disease of interest (in this case, brain cancer). Although prospective studies avoid the biases inherent in case-control studies, they are expensive and difficult to carry out, especially for rare diseases such as brain cancer.
But now researchers can take advantage of the exponential increase in exposure to cell phones since their introduction in the mid-1980s. In the space of several decades, humans have gone from having no exposure—zero percent of the population exposed—to nearly universal exposure. This means that we can take advantage of what is referred to as a “natural experiment,” the approach that Li and Muscat take in their illuminating new study.
An earlier analysis of this type was carried out by the National Cancer Institute. That study showed no evidence of an association between cell phone use and cancer, but the data only went up to 2012. Possibly cell phones had not been in use long enough for an effect to show up. Li and Muscat extend the period of observation by nine years.

The authors conclude that “these findings suggest that mobile phone use does not appear to be associated with an increased risk of brain cancer, either malignant or benign.””

“in the face of this evidence, RFK Jr. insists on propagating this debunked claim, and he is sponsoring a study by a discredited researcher that he hopes will provide the answer he favors. This is an unforgivable waste of money that could be spent on addressing an important health issue. But it is also more than that.
From observing RFK Jr., and those he appeals to, we see that the belief in different bogus claims tends to be correlated. A belief that cell phones are causing cancer or that vaccines cause autism can serve as a sentinel indicator of the susceptibility to other false beliefs, such as those targeting pesticides and genetically engineered crops. It’s noteworthy that the prominent anti-biotech advocacy organization U.S. Right-to-Know is anti-vaccine in addition to being fiercely against glyphosate and other pesticides and genetically modified crops.
These, and many others, are zombie risks that never die. It doesn’t matter what the specific risk is. The credulity, the failure to take any commonsense evidence or distillations of the scientific evidence into account, the refusal to value the judgment of experts who have spent untold hours examining the issue, or the conclusions reached by institutions such as the National Institutes of Health, the Institute of Medicine, or the American Cancer Society, into account are the same.
RFK Jr. appears to have an implacable drive to do away with vaccines by undermining public confidence, disrupting insurance coverage, and making it too costly for pharmaceutical companies to produce them, as happened in the 1980s. Exposing his lies is literally a matter of protecting the lives of children and adults from the all-too-real infectious diseases that RFK Jr. doesn’t believe in.”
