No link found between cancer, mobile phones

NO CLEAR evidence of a link between mobile phones and brain cancer has been found in the largest cohort study to date.

Researchers found in an 18-year study of almost ­360,000 Danish mobile phone subscribers and a total 10,729 cases of central nervous system tumour that the incidence among subscribers was comparable to non-subscribers.

Even when restricted to those with phone contracts spanning more than 10 years, there was little difference in the rate of incidence of glioma or meningioma for those exposed to phones compared to non-exposed individuals, the researchers found.

However Professor Bruce Armstrong, from the University of Sydney’s School of Public Health, cautioned that the study was based on phone subscriptions that did not account for volume of use.

Considerable uncertainty remained about a mobile phone cancer link, he said.
