I know most of us worry about the risk of using cell phones. Here is an article which may reassure you…
Cell Phones and Cancer
By EarthTalk – Feb 12, 2011
(HealthNewsDigest.com) – Cell phones have only been in widespread use for a couple of decades, which is far too short a time for us to know conclusively whether or not using them could cause cancer. Research thus far appears to indicate that most of us have little if anything to worry about.
According to the federally funded National Cancer Institute, the low-frequency electromagnetic radiation that cell phones give off when we hold them up to our heads is “non-ionizing,” meaning it cannot cause significant human tissue heating or body temperature increases that could lead to direct damage to cellular DNA. By contrast, X-rays consist of high-frequency ionizing electromagnetic radiation and can lead to the kind of cellular damage resulting in cancer. Nonetheless, some cell phone users and researchers still worry about our cell phone usage, given how much we now use them and how little we know about their potential long-term effects.
The reason the issue keeps coming up is that some initial studies in Europe, where cell phone usage caught on a decade before the U.S., showed links between some forms of tumors and heavy cell phone usage. As a result, researchers teamed up to do a more definitive study, called the “Interphone” study, across 13 countries between 2000 and 2004. The results, published in May 2010 in the peer-reviewed International Journal of Epidemiology, indicated no increased risk of developing two of the most common types of brain tumors, glioma and meningioma, from typical everyday cell phone usage. Study participants who reported spending the most time on their phones showed a slightly increased risk of developing gliomas, but researchers considered this finding inconclusive due to factors such as recall bias, whereby participants with brain tumors may have simply remembered past cell phone use differently from healthy respondents.
Researchers looking to get past the relatively short timing window and the recall bias issues of the Interphone study recently launched a longer term study, dubbed COSMOS (short for Cohort Study on Mobile Communications), in Europe. Some 250,000 cell phone users between the ages of 18 and 69 and located in Britain, Finland, the Netherlands, Sweden and Denmark will participate by allowing researchers to track their cell phone usage and health over three decades. According to an April 22, 2010 article in Reuters, the study will factor in the use of hands-free devices and how people carry their phones and will also be on the lookout for links to neurological diseases such as Parkinson’s and Alzheimer’s.
There are some precautions you can take to minimize whatever risk may exist. The Federal Communications Commission (FCC) suggests reserving the use of cell phones for shorter conversations, or for times when a conventional phone isn’t available. Also, using a hands-free device places more distance between the phone and your head, significantly reducing the amount of radiation exposure. If the fact that many states require hands-free devices for using a cell phone while driving isn’t enough to make you go out and spend the extra money on such an accessory, maybe the cancer risk, perceived or real, will.
So I guess it is OK to call away… I use my “speaker” option so I can talk with the phone away from my head whenever possible.
Feel good and keep smiling! Pat
