Esempio di disinformazione , negli USA

Nella rivista indubbiamente qualificata quale la Newscientist è apparso un articolo a commento della presentazione dei primi risultati dello studio del NTP dicendo di rilassarsi perché i risultati riportano un leggero incremento del 3% dei tumori al cervello, a livelli di esposizione superiori a quelli ammessi in USA, e che i dati potrebbero statisticamente rientrare nella norma.

Cindy Sage ha immediatamente scritto alla rivista (ma verrà pubblicata ? che fine farà ? forse con caratteri micro in qualche rubrica ... di Posta !) che quanto riportato dice esattamente l'opposto

nel dettaglio

Contrary to this article, legal radiation levels resulted in more cancers.

The US National Toxicology Program results as presented by the study's principal author this month tell us the opposite is true to what New Scientist has reported.  Cell phone radiation has significantly increased the risk for malignant brain tumors of the kind also increasing in humans who use cell phones.  Male rats in this study were exposed to cell phone radiation at levels typical of heavy use in humans.  It resulted in a statistically-significant increased risk for glioma (brain cancer) and a rare tumor of the heart.  Both have been reported to occur with cell phone radiation exposure in human studies over the last decade, including the massive 13-country Interphone study (2010).  The exposure levels are below current public safety standards, meaning existing safety limits are outdated and inadequate to protect public health.  This is a gold-standard federal study that took 16 years and $25 million in federal funding.  These results should be accurately reported and not dismissed.  We now have both animal studies and human epidemiology studies that report statistically significant, dose-response relationship to legal levels of cell phone radiation as the phones are currently used by millions of people around the world.  Are increased cancer rates showing up in cancer registries?  Yes.  Cancer registry studies in the US show a two- to three-fold increased risk for primary malignant brain tumors (increased frontal (APC +2.4% to +3.0%, P ≤ 0.001) and temporal (APC +1.3% to +2.3%, P ≤ 0.027) lobe glioblastoma multiforme (GBM) tumors. (Zada et al,  World Neurosurg. 2012 Mar-Apr;77(3-4):518-24. doi: 10.1016/j.wneu.2011.05.051. Epub 2011 Nov 7).  Other countries are also reporting increased rates of this deadly brain tumor.  Females did not show increased cancer rates, but gender differences are common in animal toxicology studies and do not undercut the evidence of male rate cancers.  The number of cancerous tumors is not small; it one in sixteen (16) male rats.  The number of pre-cancerous lesions combined with malignant tumors is one in twelve (12) which is not a small increase.
