Radiofrequency radiation from mobile phones and the risk of breast cancer: A multicenter case-control study with an additional suspected comparison group
A multicenter case-control study in Iran reported that self-reported prolonged mobile phone use was associated with higher odds of confirmed and suspected breast cancer status. The authors emphasize that the findings do not imply causation and note limitations including self-reported exposure and potential residual confounding. They call for larger prospective studies with objective exposure assessment.
Key points
- Study design: multicenter case-control with three groups (controls, suspected cases, confirmed invasive breast cancer) recruited from diagnostic/mammography/radiotherapy centers in Iran.
- Exposure assessment relied on structured questionnaires covering call duration, screen time, and phone placement, alongside demographic/reproductive/lifestyle/environmental factors.
- In fully adjusted models, >60 minutes/day of mobile phone conversations was associated with higher odds of confirmed breast cancer (OR 3.49, 95% CI 1.02–11.97) versus <10 minutes/day.
- The same exposure category was also associated with higher odds of being in the suspected group (OR 10.84, 95% CI 2.29–51.41) versus <10 minutes/day.
- Longer screen time (>4 h/day) and other factors (e.g., lower education, environmental pollutants) were also reported as associated with increased odds.
- Authors caution that self-reported exposures and residual confounding limit interpretation and recommend prospective studies with objective exposure measures.
