The potential carcinogenicity of non-ionizing radiation has been a topic of extensive research and debate. The International Agency for Research on Cancer (IARC) has classified radiofrequency electromagnetic fields (RF-EMF) as "possibly carcinogenic to humans" (Group 2B), based on limited evidence of an increased risk for glioma, a malignant type of brain cancer. However, the evidence is not conclusive, and more research is needed to establish a definitive link.
