No link between mobiles and brain cancer

                There is no link between increasing mobile phones use and brain cancer, claims a new study by researchers from University of Sydney. They found no rise in tumours over 30 years in Australia despite widespread use of the devices. There were significant increases in brain cancer incidence only in those aged 70 years or more. But the increase in incidence in this age group began from 1982, before the introduction of mobile phones in 1987 and so could not be explained by it. The most likely explanation of the rise in this older age group was improved diagnosis.
