Cell Phones and Brain Cancer -- Jury Still Out
October 14, 2009 — Cellular telephones have become an integral part of everyday life; they are now used by an estimated 4 billion people worldwide. But this is a relatively new technology, and there are lingering concerns about health risks, in particular a risk for brain cancer.
A new report suggests that that regular use of cell phones can result in a "significant" risk for brain tumors. But previous studies have been inconsistent. Even so, some European countries have taken precautionary measures, aimed specifically at children.
Cell phones can be made safer, and the technology to do so exists right now. For example, said Mr. Morgan, "you can get a 10,000-fold reduction in exposure simply by keeping the phone 6 inches away from the head."
There are also steps that can be taken right now to make cell phones safer to use, he said. These include using a wired headset (not a wireless headset such as a Bluetooth), using speaker-phone mode, or sending text messages; keeping the phone away from the body when not in use; avoiding use in a moving car, train, or bus, or in rural areas at some distance from a cell tower, because any of these uses will increase the power of the cell phone's radiation; and keeping the cell phone turned off until you need to use it.
The authors also recommend using a corded land-line phone whenever possible, instead of a wireless phone, and to avoid cell phones when inside buildings, particularly with steel structures. Since children face a greater health risk, they should not be allowed to sleep with a cell phone under their pillows or at the bedside, said Mr. Morgan. Ideally, those younger than 18 years should not use a cell phone at all, except for emergencies.
