Chest X-rays for lung cancer and Pap tests for cervical cancer have received similar, albeit less definitive, criticism.CommentsView/Create comment on this paragraphThe next step in the reevaluation of cancer screening was taken last year, when researchers at the Dartmouth Institute for Health Policy announced that the costs of screening for breast cancer were often minimized, and that the benefits were much exaggerated.
