Fresh fears have been raised over the role of mobile phones in brain cancer after new evidence revealed rates of a malignant type of tumour have doubled in the last two decades.

Charities and scientists have called on the Government to heed longstanding warnings about the dangers of radiation after a fresh analysis revealed a more “alarming” trend in cancers than previously thought.

However, the new study, published in the Journal of Public Health and Environment, has stoked controversy among scientists, with some experts saying the disease could be caused by other factors.

The research team set out to investigate the rise of an aggressive and often fatal type of brain tumour known as Glioblastoma Multiforme (GBM).

They analysed 79,241 malignant brain tumours over 21 years, finding that cases of GBM in England have increased from around 1,250 a year in 1995 to just under 3,000.

The study is the first recent effort of its kind to analyse in detail the incidence of different types of malignant tumours.

The scientists at the Physicians’ Health Initiative for Radiation and Environment (PHIRE) say the increase of GBM has till now been masked by the overall fall in incidence of other types of brain tumour.
