A distanza di 2 anni dalla pubblicazione delle conclusioni della IARC (Agenzia Internazionale per la Ricerca sul Cancro) riguardo il rapporto tra radiofrequenze e alcuni tipi di tumori cerebrali:
viene pubblicata l’intera monografia dedicata alla ricerca IARC.
Non-Ionizing Radiation, Part 2: Radiofrequency Electromagnetic Fields ( .pdf – 6Mb)
Alcune rilevanti conclusioni:
Cancer in Humans
There is limited evidence in humans for the carcinogenicity of radiofrequency radiation. Positive associations have been observed between exposure to radiofrequency radiation from wire- less phones and glioma, and acoustic neuroma.
Radiofrequency electromagnetic fields are
possibly carcinogenic to humans (Group 2B).
Rationale of the evaluation of the epidemiological evidence
The human epidemiological evidence was mixed. Several small early case–control studies were considered to be largely uninformative. A large cohort study showed no increase in risk of relevant tumours, but it lacked information on level of mobile-phone use and there were several potential sources of misclassification of expo- sure. The bulk of evidence came from reports of the INTERPHONE study, a very large inter- national, multicentre case–control study and a separate large case–control study from Sweden on gliomas and meningiomas of the brain and acoustic neuromas. While affected by selection bias and information bias to varying degrees, these studies showed an association between glioma and acoustic neuroma and mobile-phone use; specifically in people with highest cumula- tive use of mobile phones, in people who had used mobile phones on the same side of the head as that on which their tumour developed, and in people whose tumour was in the temporal lobe of the brain (the area of the brain that is most exposed to RF radiation when a wireless phone is used at the ear). The Swedish study found similar results for cordless phones. The comparative weakness of the associations in the INTERPHONE study and inconsistencies between its results and those of the Swedish study led to the evaluation of limited evidence for glioma and acoustic neuroma, as decided by the majority of the members of the Working Group. A small, recently published Japanese case–control study, which also observed an association of acoustic neuroma with mobile- phone use, contributed to the evaluation of limited evidence for acoustic neuroma.
There was, however, a minority opinion that current evidence in humans was inadequate, therefore permitting no conclusion about a causal association. This minority saw incon- sistency between the two case–control studies and a lack of exposure–response relationship in the INTERPHONE study. The minority also pointed to the fact that no increase in rates of glioma or acoustic neuroma was seen in a nation- wide Danish cohort study, and that up to now, reported time trends in incidence rates of glioma have not shown a trend parallel to time trends in mobile-phone use.
