A new study into the dangers of mobile phones has found no connection between the use of cell phones and increased risk of brain tumors.

    BEIJING, April 13 -- A new study into the dangers of mobile phones has found no connection between the use of cell phones and increased risk of brain tumors. The studied, conducted in Denmark, was published Tuesday by the American Academy of Neurology.

    Researchers questioned more than 1,200 people, of whom 822 were healthy and 427 had brain tumors. When they compared the two groups, they found the risk of developing a brain tumor was not related to the frequency of mobile phone calls or the number of years they had been used.

    The Danish study looked at the two main types of brain tumor "glioma and meningioma" and found that neither was linked to mobile phone use.

    They also found that there was no association between the side of the head habitually used by a mobile phone user and on which side of the brain a tumor developed.

    The findings are consistent with other studies, Dr. Christoffer Johansen of the Danish Cancer Society, said in a statement. Johansen was one of the study's authors.

    "These results are in line with other large studies on this question, including a recently published large-scale, population-based study by the Swedish Interphone Study Group," Johansen said. "There have been a few studies that found an increased risk of brain tumors with cell phone use, but those studies have been criticized for problems with the study design."

    Several laboratory studies have suggested that the radiation emanating from mobile phones could damage living tissues and one in particular demonstrated that a long conversation on a mobile phone can cause small temperature rises in the brain.

    Professor Johansen said the latest study published in the journal Neurology was the most comprehensive and detailed so far but it did not include children so the findings were only applicable to adults. Enditem
