The 2024 COSMOS Study involved more than 250,000 mobile-phone users, many with 15 or more years of regular use, and found no higher risk of brain tumors compared with light users.
Notes on verification
Confirmed by peer-reviewed publication (Feychting et al. 2024, Environment International), IARC official summary, BfS, and Karolinska Institutet press release, all consistent in figures and conclusions.
