More and more experts are saying that cell phones may pose a very serious health risk by increasing your chance of developing a brain tumor.
That means that over 270 million Americans may be playing Russian roulette with their cell phones every day. Each year, more than 21,000 adults and 1,500 children are diagnosed with brain tumors, and researchers believe some of them may have been caused by talking on a mobile phone.
A new study examined a decade's worth of research and concluded that people who use cell phones for more than 10 years are up to 30% more likely to develop brain tumors than people who rarely use them.
Every time we call to say we're late for a meeting or to ask if we can pick something up at the store, the cell phones we use are emitting radiofrequency radiation. While not as damaging as the radiation from X-rays, it can still affect our DNA. In fact, animal studies have shown that the radiation from cell phones can change the cells inside their brains. Whether those changes will cause serious damage is still up for debate. But because cell phone use is a relatively recent phenomenon, and brain cancer can take many years to develop, some scientists warn we will not see the results until it is too late.
A group of researchers from South Korea and California analyzed 23 studies that looked at the association between tumors and mobile phone use. As a group, the studies did not show an increased risk, but when the researchers focused on the higher quality studies and the longer-term use studies, they discovered about a 30 percent increased risk of tumors.
Children's brains are thinner and contain more fluid than adult brains, which means they can more readily absorb electricity. Mathematical models show that when children hold a mobile phone up to their ears, the brain surface they expose to radiation is more than double that of adults. Some countries, including Finland and Israel, have already issued warnings that children not use cell phones, and Maine recently passed an emergency bill mandating warning labels about children and cell phones.More and more experts are saying that cell phones may pose a very serious health risk by increasing your chance of developing a brain tumor.

There are three main reasons why people are concerned that cellular telephones (also known as "wireless" or "mobile" telephones) may cause certain types of cancer:
• Cellular telephones emit radiofrequency (RF) energy (radio waves), which is a form of radiation that is under investigation for its effects on the human body.
• Cellular telephone technology emerged in Europe in the 1980s but did not come into widespread use in the United States until the 1990s. The technology is rapidly changing, so there are few long-term studies of the effects of RF energy from cellular telephones on the human body.
• The number of cellular telephone users has increased rapidly. As of December 2008, there were more than 270 million subscribers to cellular telephone service in the United States, according to the Cellular Telecommunications and Internet Association. This is an increase from 110 million users in 2000 and 208 million users in 2005.
For these reasons, it is important to learn whether RF energy from cellular telephones affects human health.
