- Electromagnetic waves are used in radio, Wi-Fi, GPS, and mobile phones, sparking concerns about brain cancer risk from mobile phone use.
- A new study analyzing 2019 WHO-commissioned reviews found no evidence that mobile phone electromagnetic waves cause brain, head, or neck cancer, even with heavy or long-term use.
- Historical fears of low-energy radiation, like from microwaves and TVs, stem from the Cold War, but no consistent health effects have been proven for such exposure.
- High-energy radiation, such as X-rays, is known to cause cancer, leading to public concern over all radiation types, despite safety standards limiting emissions from consumer electronics.
- The WHO reviews covered health effects including fertility, headaches, tinnitus, and cancer, with findings indicating no evidence linking mobile phone use to adverse health outcomes.
- Evidence quality for many health effects is limited or low, but brain cancer studies received high-quality ratings, and brain cancer rates in Australia have remained stable since the 1980s.
- The key takeaway is no clear association between mobile phone use and brain, head, or neck cancers, suggesting current exposure limits are likely safe, though ongoing research is recommended.
