An European Study has revealed that a few years of cell phone use does not raise a risk of brain cancer in children.

Research has also been conducted on adults which has shown positive results, although a previous statement by the World Health Organization earlier this year said that cell phone usages poses a threat to users.

A team of Swiss scientists investigated more than 350 children aged between 7 and 19 who were diagnosed with brain cancer between 2004 and 2008 in Denmark, Norway, Switzerland and Sweden. The scientists interviewed the kids about their cell phone use and compared the result with more than 600 teens.

The team found out that both the groups have been regular cell phone users and reported it in the Journal of the National Cancer Institute. Children, who admitted they started to use cell phones at least five years earlier, were not at risk of cancer than those who never regularly used them.

The researchers managed to check the phone records for a group of kids and said that a few dozen who had cell phone service the longest, about three years or more, did, however, have an increased risk.

"This is a very important study," said Elizabeth Ward of the American Cancer Society, but one that will be debated. "It is important that additional studies be done in children, adolescents and young adults with early life exposure to mobile phones."

The Cancer society, however, has asked people who are concerned about a possible threat can keep the phone away from their heads and limit children's use, according to a Forbes report.
