Importante pubblicazione sul rischio
GLIOMI in utilizzatori di cellulari e cordeless.
Gli autori oncologi svedesi prendendo
in considerazione gli 8 punti di Bradford Hill,dimostrano in modo acclarato il
nesso di causalità tra l'esposizione alle radiazioni e.m e la genesi
tumorale.
Conclusione : Le radiazioni RF devono essere considerate come un
cancerogeno umano che causa gliomi ( tumori al cervello )
Dedicato a chi
continua a sostenere che non esistono evidenze scientifiche.

ABSTRACT
Objective. Bradford
Hill's viewpoints from 1965 on association or causation were used on glioma
risk and use of mobile or cordless phones. Methods. All nine
viewpoints were evaluated based on epidemiology and laboratory studies. Results. Strength:
meta-analysis of case-control studies gave odds ratio (OR) = 1.90, 95%
confidence interval (CI) = 1.31-2.76 with highest cumulative exposure.
Consistency: the risk increased with latency, meta-analysis gave in the 10+
years' latency group OR = 1.62, 95% CI = 1.20-2.19. Specificity: increased risk
for glioma was in the temporal lobe. Using meningioma cases as comparison group
still increased the risk. Temporality: highest risk was in the 20+ years'
latency group, OR = 2.01, 95% CI =1.41-2.88, for wireless phones. Biological gradient:
cumulative use of wireless phones increased the risk. Plausibility: animal
studies showed an increased incidence of glioma and malignant schwannoma in
rats exposed to radiofrequency (RF) radiation. There is increased production of
reactive oxygen species (ROS) from RF radiation. Coherence: there is a change
in the natural history of glioma and increasing incidence. Experiment:
antioxidants reduced ROS production from RF radiation. Analogy: there is an
increased risk in subjects exposed to extremely low-frequency electromagnetic
fields.
Conclusion.
RF radiation should be regarded as a human carcinogen
causing glioma.
