Objective:

To synthesize and analyse systematic reviews, case-control studies, cohort studies and meta-analysis that investigate the association between exposure to radiofrequency from mobile phones and the appearance of tumours in adults.

Methods:

A systematic search was conducted in Scopus, Web of Science, The Cochrane Library, Medline and Cinahl of articles published in English and Spanish between January 2005 and February 2016 that analyse the risk of tumour associated with exposure to radiofrequency from mobile phones in adults. The recommendations of the PRISMA Declaration were followed, and the quality of the articles was analysed with the AMSTAR tool and the Newcastle-Ottawa Scale.

Results:

1034 studies were found, fourteen of which were included. Most studies agree that it is not possible to determine a relationship in the short term, although long-term (over 10 years) radiofrequency emitted by mobile phones can cause tumour effects, with an increased risk by ipsilateral exposure and latency.

Conclusions:

Although radiofrequency from mobile phones has tumour effects on humans, the available scientific evidence is not robust. More rigorous follow-up studies with larger sample sizes and broader periods are necessary to learn more about the long-term effects.
