Hour A Day Raises Cellphone Cancer Risk
Cellphones are at the centre of new safety fears in Britain since
scientists have found the first evidence of a link with brain cancer. Users
who spend more than an hour a day talking on a cellphone are almost a third
more at risk of developing a rare form of brain tumour, a study has found.
But the biggest British study three years ago, led by the government's former chief scientific adviser, William Stewart, found that there was no evidence of a risk to human health.
A report by the American National Cancer Institute in 2001 also failed to find a link between mobile phone use and brain cancer.
The latest findings are the first to show a link between the instruments and disease in humans.
In the study, lead researcher Kjell Mild examined the medical records of 1 600 tumour victims who had been using cellphones for up to 10 years before diagnosis. Mild, a biophysicist at Orebro University in Sweden, said the evidence was clear: "The more you use phones and the greater number of years you have them, the greater the risk of brain tumours."
The study found that spending more than an hour a day on the phone increased the risk of a type of tumour known as acoustic neuroma by 30 percent.
