Mobile phones 'not linked to brain tumours'Study finds mobile use doesn't raise cancer risk
06 December 2006
People who regularly use a mobile phone do not have an increased risk of developing brain tumours, a major study has found.
The Danish study, which is the largest and longest-running probe into the possible cancer link, suggests there is no association between the two.
It followed 420,000 Danish mobile phone users for up to 21-years and discovered that mobile phone users have no greater chance of developing the disease than the general population.
The researchers, from the Danish Institute of Cancer Epidemiology in Copenhagen, looked at data on people who had been using mobiles between 1982 and 1995.
More than 55,000 of the study group had been using a mobile phone for at least 10 years.
Their health was then followed until 2002. Researchers found no evidence to suggest users had a higher risk of tumours in the brain, eye, salivary gland or leukaemia.
A total of 14,249 cases of cancer were recorded which was a similar number to the expected total of 15,001 meaning mobile phone use had no impact on the risk of cancer.
The researchers concluded: ‘We found no evidence for an association between tumour risk and cellular telephone use among either short-term or long-term users.
‘Moreover, the narrow confidence intervals provide evidence that any large association of risk of cancer and cellular telephone use can be excluded.’
The study, published in the Journal of the National Cancer Institute, backs the findings of a report earlier this year by the Institute of Cancer Research which concluded that using a mobile phone is not linked to an increased risk of brain tumours.
More than 40 million people in the UK are thought to use mobile phones, including many children.
Last year Health Protection Agency Chairman, Sir William Stewart, called on parents to ban children under eight from using mobile phones.
He also said he wanted teenagers to restrict their use and rely more on sending text messages.
Some scientists believe youngsters are at greatest risk from the potentially damaging health effects of mobile phone emissions.
They advise youngsters to limit mobile phone use as a precautionary measure as their nervous system may still be developing.
