Background: GLOBOCAN projections estimate that by 2045 Ecuador will register 6,678 new cases and 2,190 deaths from breast cancer, representing increases of 71.1% in incidence and 89.8% in mortality, positioning it as a significant public health problem. Objectives: To analyze changes in breast cancer incidence, mortality, and survival in Quito between 1985 and 2019. Methods: Age-standardized incidence and mortality rates were calculated using data from the Quito Population-Based Cancer Registry. Joinpoint regression models were applied to identify variations in trends, and the distribution of cases according to TNM stage at diagnosis and five-year overall survival was evaluated. Results: Between 1985 and 2019, a sustained increase in both incidence and mortality was observed. Since the late 1990s, diagnoses at stage I have increased, while five-year survival remained stable. Conclusions: The burden of breast cancer continues to rise, highlighting limitations in early detection and timely treatment. It is a priority to strengthen prevention strategies and move towards an organized, equitable, and sustainable program that guarantees comprehensive care for all women.
