COSMOS: Prospective Cohort Study: Mobile Phone Use and Brain Tumur Risk
“Our findings suggest that the cumulative amount of mobile phone use is not associated with the risk of developing glioma, meningioma or acoustic neuroma.”
From Denmark, Finland, the Netherlands, Sweden and the U.K. (but not France). Team includes Maria Feychting, Joachim Schüz, Anssi Auvinen, Anke Huss, Christoffer Johansen and Paul Elliott.
The COSMOS paper does not mention the different types of glioma, notably glioblastoma (GBM), the most aggressive type of brain tumors.
Yet, Supplementary Table S1 shows ~70% of gliomas in the COSMOS study population are GBM, which is higher than the expected ~50%. Note also that, according to Table S2, 64% of COSMOS pop is female. Men are much more likely to get GBM than women. So the percentage of GBM in the COSMOS cohort is even higher than expected.
None of this is discussed!
This elevated rate of GBM in the COSMOS cohort is important because it supports past unexplained findings of higher incidences of GBM in Denmark, England, the Netherlands & Sweden —all part of COSMOS.
