I always get a fearful emotional when I hear a study of disease say that the average person does or does not get cancer. I had concluded over a decade ago to minimize cell phone use because a study in Sweden took into account how many and how long those with brain cancer attributed to cell phone use increased cancer risk.
Rarely mentioned is that those in weak signal areas are prone to more microwave radiation because the cell companies boost power to reach those areas.
… Brain cancer is a concern that Ms. Davis takes up. Over all, there has not been a general increase in its incidence since cellphones arrived. But the average masks an increase in brain cancer in the 20-to-29 age group and a drop for the older population. …
Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiofrequency radiation had damaged brain DNA. He maintains a database that holds 400 scientific papers on possible biological effects of radiation from wireless communication. He found that 28 percent of studies with cellphone industry funding showed some sort of effect, while 67 percent of studies without such funding did so. “That’s not trivial,” he said. …
The authors included some disturbing data in an appendix available only online. These showed that subjects who used a cellphone 10 or more years doubled the risk of developing brain gliomas, a type of tumor.
The 737 minutes that we talk on cellphones monthly, on average, according to the C.T.I.A., makes today’s typical user indistinguishable from the heavy user of 10 years ago. Ms. Davis recommends keeping a phone out of close proximity to the head or body, by using wired headsets or the phone’s speaker. Children should text rather than call, she said, and pregnant women should keep phones away from the abdomen. … http://www.nytimes.com/2010/11/14/business/14digi.html?src=me&ref=general

WARNING: Holding a cellphone against your ear may be hazardous to your health. So may stuffing it in a pocket against your body.
I’m paraphrasing here. But the legal departments of cellphone manufacturers slip a warning about holding the phone against your head or body into the fine print of the little slip that you toss aside when unpacking your phone. Apple, for example, doesn’t want iPhones to come closer than 5/8 of an inch; Research In Motion, BlackBerry’s manufacturer, is still more cautious: keep a distance of about an inch.
The warnings may be missed by an awful lot of customers. The United States has 292 million wireless numbers in use, approaching one for every adult and child, according to C.T.I.A.-The Wireless Association, the cellphone industry’s primary trade group. It says that as of June, about a quarter of domestic households were wireless-only.
If health issues arise from ordinary use of this hardware, it would affect not just many customers but also a huge industry. Our voice calls — we chat on our cellphones 2.26 trillion minutes annually, according to the C.T.I.A. — generate $109 billion for the wireless carriers.
The cellphone instructions-cum-warnings were brought to my attention by Devra Davis, an epidemiologist who has worked for the University of Pittsburgh and has published a book about cellphone radiation, “Disconnect.” I had assumed that radiation specialists had long ago established that worries about low-energy radiation were unfounded. Her book, however, surveys the scientific investigations and concludes that the question is not yet settled. … http://www.nytimes.com/2010/11/14/business/14digi.html?src=me&ref=general
