Our objective was to compare breast cancer mortality in two regions of the Republic of Ireland that introduced a screening programme eight years apart. and to estimate the steady-state mortality deficits the programme will produce. We carried out age- and year-matched between-region comparison of breast cancer mortality rates. and of incidence rates of stage 2-4 breast cancer. https://ashleyshomestores.shop/product-category/rect-drm-counter-tbl-set3-cn/
