Methods Patients with brain tumour from the Australian, Canadian, French, Israeli and New Zealand components of the Interphone Study, whose tumours were localised by neuroradiologists, were analysed. Controls were matched on age, sex and region and allocated the 'tumour location' of their matched case. Analyses included 553 glioma and 676 meningioma cases and 1762 and 1911 controls, respectively. RF dose was estimated as total cumulative specific energy (TCSE; J/kg) absorbed at the tumour's estimated centre taking into account multiple RF exposure determinants.
Results ORs with ever having been a regular mobile phone user were 0.93 (95% CI 0.73 to 1.18) for glioma and 0.80 (95% CI 0.66 to 0.96) for meningioma. ORs for glioma were below 1 in the first four quintiles of TCSE but above 1 in the highest quintile, 1.35 (95% CI 0.96 to 1.90). The OR increased with increasing TCSE 7+ years before diagnosis (p-trend 0.01; OR 1.91, 95% CI 1.05 to 3.47 in the highest quintile). A complementary analysis in which 44 glioma and 135 meningioma cases in the most exposed area of the brain were compared with gliomas and meningiomas located elsewhere in the brain showed increased ORs for tumours in the most exposed part of the brain in those with 10+ years of mobile phone use (OR 2.80, 95% CI 1.13 to 6.94 for glioma). Patterns for meningioma were similar, but ORs were lower, many below 1.0.
Conclusions There were suggestions of an increased risk of glioma in long-term mobile phone users with high RF exposure and of similar, but apparently much smaller, increases in meningioma risk. The uncertainty of these results requires that they be replicated before a causal interpretation can be made."

Volta e meia sai um artigo a dizer exactamente isso: uso prolongado de telemóveis causa tumores. Ao mesmo ritmo, aparecem outros a dizer o contrário: não há correlação entre as duas coisas.
Na minha mera opinião, acho que estamos expostos a tanta radiação no dia a dia, que não são 15 ou 30 minutos de telemóvel por dia que alteram as probabilidades do tumor surgir.
Estudo caso controlo e muito frágil, os proprios autores o reconhecem. Como tudo ha k ter bom senso.
O prof AVC disse que não fazia, não é que não fazia, que não estava ainda comprovado.
Eu tb sou pela moderação, pelo sim, pelo não... :P
estas cenas assustam-me quando penso que ha uns anos toda a gente pensava que o tabaco era coisa fixe ...e agr é o k é...
vai na volta, daqui a uns anos descobrimos algo semelhante para os telemoveis e caput =/
