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. The new study, published in the Journal of Public Health and Environment … set out to investigate the rise of an aggressive and often fatal type of brain tumour known as Glioblastoma Multiforme (GBM). [It found] that cases of GBM in England have increased from around 1,250 a year in 1995 to just under 3,000. 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. The group said the increasing rate of tumours in the frontal temporal lobe “raises the suspicion that mobile and cordless phone use may be promoting gliomas”. Professor Denis Henshaw said: “Our findings illustrate the need to look more carefully at, and to try and explain the mechanisms behind, these cancer trends, instead of brushing the causal factors under the carpet and focusing only on cures.” The new study list causal factors aside from mobile phone use that may explain the GMB trend, including radiation from X-rays, CT scans and the fallout from atomic bomb tests in the atmosphere.
