Children and teens who use cell phones are not at increased risk of getting brain cancer, according to a new Swiss study.

We did not find that young mobile phone users have an increased risk for brain tumors when regularly using mobile phones

says study researcher Martin Roosli, PhD, of the Swiss Tropical and Public Health Institute, University of Basel.

Nor did they find a link with longer use.

We did not see that the risk increased after five years or more since the first use of mobile phones

Among the results of the study:

  • The parts of the brain with the highest exposure to the phone’s radio-frequency waves were not linked with an increased risk of brain cancer among regular users.

Furthermore, Roosli says:

The incidence of brain cancers has not risen over the last 20 years in countries with widespread cell phone use, which further refutes a link

My Opinion

This is just another study in a recent stream of studies that shows at cell phones do not cause brain cancer. Although cell phones do produce radiation, it is not the same kind of radiation that people should be worrying about. For an explanation of this and why there is not a plausible connection due to physics, refer to this previous post about cell phones and brain cancer.

With all of these studies piling up behind the claim that cell phones do not cause brain cancer, we should be wary of all the fear-mongering. Yes, technology can be scary. And yes, when it comes to your brain or your child’s brain, you can never be too safe. But with the science behind us, we have one less thing to worry about (until proven otherwise with many conclusive studies, which we don’t have).

There are whole websites devoted to selling products which supposedly block the radiation put out by cell phones and other electronic devices. All of the websites like this and their products are rife with pseudoscience, with “life protecting” products that do basically nothing, except make your wallet lighter.

So we have to remain skeptical, and keep science on our side. Because we have the science on the side of no link between cell phones and brain cancer, you can save your time, money, and brain.
