Trends in breast cancer mortality in Mexican women

To estimate age-adjusted mortality rates at the national and state levels, evaluates trends and their spatial distribution during the period 2000-2023 among Mexican women.

Ecological study conducted from open access data, the age-standardized mortality rate of breast cancer during the period 2000-2023 was calculated. Joinpoint regression models were estimated for breast cancer mortality in Mexico and its states. Spatial analysis was performed using Moran's I statistic.

The age-adjusted mortality rate at the national level during 2000 was 18.99 per 100,000 women, the highest mortality rate occurred in the year 2020. Joinpoint analysis shows a decrease in mortality in the last five years, being greater in urban areas. For 2023, the highest mortality occurred in Sonora and Chihuahua, while Mexico City (-0.71; 95%CI -0.98 to -0.44) was the entity that showed a significant reduction in the mortality rate from breast cancer. The spatial analysis showed a local indicator of spatial association of 0.458 (p<0.05) for 2000 and 0.524 (p<0.05) for 2023 in the northern states of the country.

Public health interventions must be implemented according to the social, economic, and cultural context to reduce mortality from breast cancer.
