In mid-2015 my younger self wrote an editorial in the pages of the Current Oncology journal (titled, fittingly, "Through a glass darkly: the mammography debate") that the mammography debate is (1) "complex;(2) that it is naïvely implausible to expect any decisive final resolution to the residual issues that will be convincing to the principle contending parties; (3) and that behind it all, the devil is in the methodology" [1]. Below, in this and a series of papers to follow, is the beginning of and early volley towards, that resolution.
