Is there any connection between cell phones and brain cancer?
Cell phones and cancer are in the news all the time now it seems. But almost everyone uses cell phones. All over the world, tens of millions of people are pressing them against their heads for hours every day. In the U.S. it is estimated that there were at least 100 million cell phone users, as of early 2002, and that number has continued to climb. So what’s the fuss? Is cancer caused by cell phones a serious concern, or the media’s panic-du-jour? A cell phone, and a household cordless phone, use a low level form of microwave radiation to send and receive their signals. (see “How do cell phones work” here.) Microwaves, as you know, are used to cook food. As the radiation penetrates tissue it causes it to heat. Is this a problem for us with cell phones? That is the current debate. Let’s examine the positions and the known evidence, without hype or prejudice. As always, EHSO will provide citations and links to the sources of any evidence provided, so you can verify it for yourself.
Dec. 3, 2009 — Scientists say they could find no substantial change in the incidence trend of brain tumors among a study group of 60,000 people five to 10 years after cell phone usage rose sharply in the countries where they lived. Cell phones have been mentioned for years as possible causes of brain tumors, but the new study, published in the Dec. 3 online issue of the Journal of the National Cancer Institute, found no cell phone-related increase during this study period. Researchers from Denmark, Finland, Norway, and Sweden say they found that the incidence of brain tumors in the studied population of people from the four countries remained stable, decreased, or showed only a gradual increase that started before the introduction of the wireless devices between 1974 and 2003. Mobile phone use in those Nordic countries rose dramatically in the mid-1990s, the study says.
