We used 2018 incident case estimates for each disease event to calculate age-specific mortality and cumulative incidence rates. The denominator was the age-specific female population for 2018 based on World Bank data. Mortality and incident case data were provided by NCC. We collapsed ages 0–24 years old and 75+ years old and applied the same event rates to all individuals in those respective categories. 25–74-year-old age group estimates were based on the specific estimates for each 5-year age category. Case rates based on TNM staging were converted to local (37%), regional (52%) and distant (11%) invasive cancer rates in consultation with local experts and the NCC. The cancer registry data did not distinguish between TNM stage 2a (local invasive cancer) and TNM stage 2b (regional invasive cancer) cases. Thus, we assumed that 50% of Stage 2 cases were 2a (local) and 50% were 2b (regional).
