The World Health Organization’s cancer committee has released a statement that heavy cell phone use (more than 30 minutes a day) may increase the risk of “glioma,” a form of malignant brain tumor. Note the use of the word “may,” which is also used in the report.
Lest we get all excited about this, let’s look at the numbers: Glioblastomas (gliomas) occur in 2–3 cases per 100,000 people in Europe and North America. The maximum increase of 40% mentioned in the report means that may increase to a total of 2.8 – 4.2 cases per 100,000 people — .0042 percent of the population.
Epidemiologically speaking, that’s a lot of cancer. Taken on an individual basis, you’re far more likely to be killed in your car on the way to the doctor, especially if you use your phone while you’re driving.
