Population-based study estimates lifetime risks and trends of breast cancer, highlighting socioeconomic disparities.
Key Points
This study aims to estimate the global, regional, and national lifetime risks and trends of breast cancer, focusing on socioeconomic disparities.
Utilized GLOBOCAN 2022 incidence and mortality data from 185 countries and WHO Mortality Database.
Analyzed lifetime risks using the adjusted for multiple primaries (AMP) method across various age groups and socioeconomic characteristics.
Retrieval of longitudinal breast cancer incidence data from 2003-2017 from the Cancer Incidence in Five Continents (CI5) Plus database.
Overall lifetime risk of developing breast cancer was 5.51% (95% CI: 5.50%-5.52%) in 2022.
Lifetime risk varied with Human Development Index (HDI), with rates of 10.37% in very high HDI regions.
A significant increasing trend in breast cancer incidence was identified in 32 out of 36 surveillance countries, with changes ranging from 0.17% to 5.84%.
