Adult brain tumours have not increased since the mid-1990s, a new study has shown.
The report, which was conducted by the Danish Cancer Society and is published in the Journal of the National Cancer Institute, studied incidence of brain tumours in Denmark, Sweden, Finland and Norway.
Among the key findings of the ten-year research project was the discovery that there had been no discernable rise in brain tumours among 20 to79 year-olds since mobile phone usage became widespread in the mid 1990s.
Mike Dolan, of the Mobile Operators Association, welcomed the study’s conclusions which he noted were in line with earlier research.
He told BBC Online: "This finding is consistent with previous studies in this field and will form part of the overall body of scientific research.
"The UK mobile phone operators are supporting a large cohort study which is a recommendation of this paper."
Some 60,000 brain tumour cases between 1974 and 2003 were investigated for the report.
