False claims prove the need for independent scrutiny of cancer screening
Despite his eminence, the previous National Cancer Director and Chief Inspector for the Care Quality Commission is the wrong person to lead another review of cancer screening. A previous review was accompanied by his announcement of the Age Extension Trial that has been criticized for being neither scientific nor ethical, and denying the six million women participants the safeguard of explicit informed consent.(1,2,3) Health departments should not mark their own homework with exaggerated claims of success;(4) the latest press release required correction after the Office of Statistics Regulation queried the 100-fold excessive claim that “hundreds of thousands of lives” have been saved(5) – particularly objectionable given that the best evidence shows screening doesn’t show differences in all-cause deaths. Whilst accountable, the National Screening Committee’s expertise should be strengthened. The government must establish trustworthy and independent scrutiny; UK Statistics should independently verify the data and the National Audit Office should examine the value. Meantime, we recommend the general public look this gift-horse in the mouth using great decision aids that are available but not yet shared with them.(6)
