A study from the UK has found that the incidence of Glioblastoma Multiforme (a malignant brain tumor) more than doubled between 1995 and 2015.[i]
Gliomas are tumors associated with glial cells (cells that support and protect neurons in the brain). They classified by cell type, by grade, and by location. Glioblastoma Multiforme (GBM) are an aggressive malignant form of the most common glioma (astrocytoma).
Critics of the study argue that the observed increase could be due to better diagnostic imaging such as MRI and a change in how the WHO classifies gliomas during the analyzed time period. But it confirms the findings of a previous study in the US that also found an increase in GBM.[ii]
While the study did not examine the possible cause of the increase, it is particularly concerning in light of recent research from the National Toxicology Program showing “clear evidence” that exposure to cellphone radiation resulted in tumors in rats. And previous research linking cellphone radiation to an increased risk of glioma led the World Health Organization (WHO) to classify radiofrequency electromagnetic fields as possibly carcinogenic.
