On the first day of the meeting, in the epidemiology session was presented the just published UK million women study.
In the introduction of this talk was briefly reviewed epidemiological evidence of the possible causal association between exposures to cell phone radiation and brain cancer. In this context was mentioned the Danish Cohort study.
The presenter spoke about the inadequacy of the exposure data in the Danish Cohort study, such like the absolute lack of radiation exposure information, like the serious misclassification of exposed and unexposed persons, like the contamination of the control population with the heavy users. Then was the shocking conclusion that the Danish Cohort study provides:
“evidence against an association between cell phone use and cancer”.
Interestingly, and disturbingly, nobody in the audience reacted to this untruthful statement.
Is it so that when the untruthful statement is repeated enough many times it begins to sound like a truth?
I sincerely hope that it is not the case.
I have written before, on several occasions, about the Danish Cohort. My most recent opinion was published in The Scientist Magazine. In this opinion piece I listed the reasons why the Danish Cohort study should be retracted. Why such harsh action is justified?
Here is the quote from this opinion piece:
“…It is clear to me that these flaws invalidate the conclusions of the Danish Cohort study. Peer-review failed, and a study that should never have got published due to its unfounded conclusions remains as a valid peer-reviewed article in the British Medical Journal. As long as the flawed study is not withdrawn it will be used by scientists and by decision makers to justify their actions…”
This is what happened yesterday. Danish Cohort study was used as evidence against association between cell phone radiation and brain cancer.
Danish Cohort does not provide such evidence. It has such enormous flaws that drawing any conclusions is not only impossible but it is scientifically unethical. Conclusions drawn by the authors of the Danish Cohort that were perpetuated in yesterday’s presentation are simply untruthful. They are not misleading, they are untruthful.
Why nobody in the large audience stood up and dared to say the “the king is naked”? I do not have answer.
Certainly the science was the big loser yesterday.
