Campi elettromagnetici e tumore al seno
Innovativo studio di ricercatori Iraniani: ricerca di correlazione tra EMF e tumore al seno.
Conclude:
In questa review, l'uso prolungato del telefono cellulare è stato associato a un aumento del rischio di cancro al seno, sia sospetto che confermato. Tuttavia, questa associazione non stabilisce una relazione causale, poiché le esposizioni sono state auto-riportate e non è possibile escludere potenziali fattori confondenti residui.
Radiofrequency radiation from mobile phones and the risk of breast cancer: A multicenter case–control study with an additional suspected comparison group
Tahmasebi S; Mortazavi SMJ, Pourghayoomi M; Sheikhzadeh P; Welsh JS et al.. Radiofrequency radiation from mobile phones and the risk of breast cancer: A multicenter case–control study with an additional suspected comparison group. Journal of Research in Medical Sciences 30(1):63, November 2025. | DOI: 10.4103/jrms.jrms_679_25
Abstract
Background: The rapid global increase in mobile phone use has raised concerns about the potential long-term health effects of radiofrequency electromagnetic fields. While most studies have focused on brain tumors, evidence regarding breast cancer remains limited. The objective of the study is to examine the association between mobile phone use and breast cancer risk among women in Iran.
Materials and Methods: In this multicenter case–control study, 226 women were recruited from diagnostic, mammography, and radiotherapy centers across Iran and classified as controls (no history of breast cancer, n = 97), suspected cases (advised to undergo mammography due to breast-related complaints or physician recommendation, n = 52), and confirmed cases (histologically verified invasive breast cancer, n = 77). Structured questionnaires collected demographic, reproductive, lifestyle, and environmental data, including mobile phone call duration, screen time, and phone placement. Associations were analyzed using multinomial logistic regression, adjusting sequentially for demographic, reproductive, environmental, and lifestyle variables.
Results: In fully adjusted models, women reporting more than 60 min of daily mobile phone conversations had higher odds of confirmed breast cancer (odds ratio [OR] = 3.49, 95% confidence interval [CI]: 1.02–11.97) and suspected status (OR = 10.84, 95% CI: 2.29–51.41) compared with those using phones <10 min daily. Longer screen time (>4 h/day), later age at menarche, lower education level, and exposure to environmental pollutants were also associated with increased odds.
Conclusion: Prolonged mobile phone use was associated with higher odds of breast cancer, but this does not imply causation. Given self-reported exposures and potential residual confounding, findings should be interpreted cautiously. Larger prospective studies with objective exposure assessment are warranted.

Conclusion
Prolonged mobile phone use was associated with increased odds of both suspected and confirmed breast cancer in this multinomial analysis. However, this association does not establish a causal relationship, as exposures were self-reported and potential residual confounding cannot be excluded. These findings should therefore be interpreted with caution, and larger prospective studies with objective exposure measurements are needed to clarify whether this relationship reflects causation or merely correlation.
