  1. Source of population: Ministry of Internal Affairs and Communications “Population Estimates”. Source of the number of breast cancer deaths: “Vital Statistics”. Average age of death: calculated according to the number of deaths, sex and age (5 years old age grade), cause of death in “Vital Statistics”. Source of crude morbidity rate and crude mortality rate: Center for Cancer Control and Information Services, National Cancer Center, Japan. Fatality rate: we calculated by dividing the crude mortality rate by crude morbidity rate
