The World Health Organisation (WHO) has taken a step back from its earlier claims that cell phones incur a tumour risk with 2.8 million-participant research pointing against the idea.A new study led by the World Health Organisation’s (WHO) International Agency for Research on Cancer head, Dr. Joachim Schuz, has found that people who had used mobile phones for over a decade were no more likely to develop a type of non-cancerous brain tumour than new phone users.
The study observed data from more than 2.8 million Danish adults and was reported in the American Journal of Epidemiology.
The tumours observed were acoustic neuromas – slow-growing, non-cancerous tumours – that cropped up in around 800 of the 2.8 million Danish subjects between 1998 and 2006. The research found that those who had used cell phones the longest had no greater risk than short term or non-users.
The news comes after the World Health Organisation’s announcement less than two months ago that labelled cell phones as a carcinogenic hazard – similar to substances like lead – that increases the risk of glioma, a malignant type of brain cancer.
The study of 20 years-worth of research and data by 31 scientists found that research for cell phone-related glioma and acoustic neuroma was limited but strong enough to draw conclusions on risk.
This research was based on an aggregation of current evidence and data in the field rather than unique evidence though.
