Overview

• INEGI’s 2024 figures place breast cancer as the leading malignant-tumor killer of Mexican women with a mortality rate of 18.7 per 100,000.
• State rates vary widely: Chihuahua tops the list at 27.6 per 100,000, Sonora fell from 27.5 to 22.3 and dropped to fifth, and Guerrero and Tlaxcala report the lowest levels at 12.7 and 12.9.
• Guanajuato’s rate climbed from 17.2 to 21.1 in a year, prompting a call for screening and reporting 17 functional mammography units in the state.
• IMSS highlights that early diagnosis yields five-year survival above 90% and urges monthly self-exams from age 20, annual clinical exams from 25, and biennial mammography for ages 40–69 or as indicated.
• Regional context underscores access gaps, with Peru reporting about 7,797 new cases annually, roughly 30% detected early, and more than 2,200 deaths each year.
