Wide Danish study: cellphones don't cause brain cancer

Denmark study shows no sign of phone cancer risk

The frequently contradicting studies on cellphones producing cancer leaned against such a verdict late Thursday after the publication of a Danish study. A very large 358,403-person, 18-year Institute of Cancer Epidemiology project in the British Medical Journal showed 356 instances of gilomas (brain cancer variants) and 846 central nervous system cancers, the same ratio as for those who didn't have a cellphone at all. Not all users had the the same use, but even those who had a cellphone for a long time, up to 13 years, showed no increased rate.

Researchers were cautious and still wanted to gauge the effect on children as well as even longer-term effects. They were likewise interested at looking at those who had to use a cellphone for work, where their use would be very heavy relative to others.

Organizations have alternated between suggesting an increased risk, such as the WHO, as well as those that have doubted the link. One of the most controversial rejecting the study, Interphone, has been criticized for omitting some respondents.

The city of San Francisco has declined to wait for proof and has proposed a contested cellphone radiation disclosure law. Although it wouldn't restrict the sale of devices, the carrier-run CTIA has objected as it believes FCC approval is enough to deem any cellphone safe. [via BBC]

    What affect does it have?

    Holding a device against your skull that emits micro-waves has not negative affects? Smoking was once considered part of a health lifestyle. When there are corporations making billions of dollars on a product they will lie.
