Breast cancer cases are projected to reach 3.5 million by 2050, with deaths rising to 1.4 million. The study attributes this increase to population growth and aging, despite stable incidence rates. Breast cancer remains the most common cancer among women, with significant contributions to disability-adjusted life-years (DALYs). Modifiable lifestyle factors account for a substantial portion of the burden, highlighting opportunities for public health interventions. Geographical disparities exist, with high-income countries experiencing lower mortality rates, while low-income regions face challenges in diagnosis and treatment.
