Figures & data

Figure 1. Breast cancer incidence (top panel) and mortality (bottom panel) by age at diagnosis in the Nordic countries 1990–2016.

Figure 2. Time trends in age-standardized and age-specific 1-, 5-, and 10-year relative survival for women diagnosed with breast cancer in the Nordic countries 1990–2016. *Age-standardized estimates of 5- and 10-year relative survival for the latest available period marked with diamonds. Period window 2013–2017 (2012–2017 for Iceland, 2013–2016 for Finland). Estimates with 95% CI in Supplementary Tables 5 and 7.

Period window 2013–2017 (2012–2017 for Iceland, 2013–2016 for Finland). Estimates of crude probability of death and life-years lost based on average background mortality in the Nordic countries (reference-adjusted measures).
