Overall, it's not clear to me why this was published. The fifth paragraph explains why it was published: “Concluding that ‘bad luck’ is the major cause of cancer would be misleading and may detract from efforts to identify the causes of the disease and effectively prevent it.” It's fairly obvious that if a study tells people most cancers are caused by bad luck and not bad actions, there will be some subset of the population that rationalizes their bad actions through such a study. If the study is inaccurate it could then actually cause additional cancers through misinformation.
