The potential link between RF radiation from mobile phones and cancer has been the subject of extensive research. The World Health Organization (WHO) and the International Agency for Research on Cancer (IARC) have classified RF radiation as "possibly carcinogenic to humans." This classification is based on limited evidence from human studies and inadequate evidence from animal studies. While some studies have suggested a potential association between long-term mobile phone use and certain types of brain cancer, such as glioma, the evidence is not conclusive.
