Radiofrequency radiation from mobile phones and the risk of breast cancer: A multicenter case-control study with an additional suspected comparison group

AI: Melanie Research RF Safe Research Library Jan 1, 2025 CONCERN MEDIUM

This multicenter case-control study in Iran (n=226) examined associations between mobile phone use and breast cancer outcomes in women. Reporting more than 60 minutes/day of phone conversations was associated with higher odds of confirmed invasive breast cancer and of being classified as a suspected case versus <10 minutes/day. The authors emphasize that the results do not establish causation and may be influenced by self-reported exposure and residual confounding, warranting cautious interpretation.

Key points

The study used a multicenter case-control design with controls, suspected cases, and histologically confirmed breast cancer cases.
Self-reported >60 minutes/day of mobile phone conversations was associated with higher odds of confirmed breast cancer compared with <10 minutes/day.
The same high call-duration category was also associated with higher odds of being in the suspected group versus controls.
Longer screen time (>4 h/day) was reported as associated with increased odds in the analysis.
Data were collected via structured questionnaires covering demographics, reproductive/lifestyle factors, and environmental exposures.
Multinomial logistic regression was used with adjustment for multiple covariates.
The authors caution that associations do not imply causation and note possible residual confounding and self-report limitations.
