The Science Media Centre asked an expert to comment on the findings, from the Danish Institute of Cancer Epidemiology in Copenhagen, that there was no link between mobile phone use and cancers of the head or neck.
Professor Tricia McKinney, Centre for Epidemiology and Biostatistics, University of Leeds, said:
“The results of this Danish cohort study are important as they have analysed data from mobile phone company records and do not rely on users remembering for up to 10 years in the past how often they used their phone. The large numbers of subscribers in the study mean we can have some confidence in the results that have not linked mobile phone use to a risk of any cancer, including brain tumours.”
