The Guardian newspaper posted an article that takes issue how the study has been reported:
Bad luck, bad journalism and cancer rates | @BobOHara @GrrlScientist | Science | The Guardian
From the article: "The big science/health news story this week is about cancer rates, with news outlets splashing headlines like ?Two-thirds of adult cancers largely ?down to bad luck? rather than genes? (for example, here) or ?Most cancer types ?just bad luck?? (here)... ...But these headlines, and the stories, are just bollocks. The work, which is very interesting, showed no such thing."
