Breast cancer in Jalisco: a spatial analysis of mortality in the 2010-2017 period

Abstract

Introduction:In 2017, INEGI reported 84,142 deaths from malignant tumors in Mexico, while the World Health Organization indicated that the breast cancer mortality rate in 2018 was 11.2 per 100,000 women. Objective: To show the trend of breast cancer mortality in women by municipality and health region of Jalisco in the 2010-2017 period. Method: Analytical study in which standardized mortality rates and relative risks of 3873 women were estimated by municipality of residence. Dispersion and central tendency spatial statistics were used. Results: The mortality rate increased from 10.7 to 13.0 per 100,000 women in the 2010-2017 period. The highest values were found in the municipalities of Chapala (21.2) and Guadalajara (19.5); the mortality rate increased in four out of every 10 municipalities, and relative risk was up to 50-fold higher in some of the western and central Jalisco municipalities. Conclusions: An annual increase of 1.0 % was observed, although it was territorially differentiated. The results represent an opportunity to improve timely detection and diagnostic processes, as well as to guarantee the coverage of services.
