Overview

• INEGI’s provisional 2024 data report 8,451 breast-cancer deaths and a national female mortality rate of about 18.7 per 100,000, confirming it as the top cancer killer of women.
• State patterns are mixed: Sonora’s rate fell from 27.5 to 22.3 per 100,000, Guanajuato rose to 21.1 after a near 25% jump, Michoacán sits at 17.3, and Chihuahua posts the highest rate at 27.6.
• Health authorities urge self-exams from age 20, an annual clinical breast exam from 25, and mammography for women 40–69, with IMSS noting five‑year survival above 90% when detected early.
• Late diagnosis remains common, with reports of roughly 70% of cases found at advanced stages, as Peru’s Minsa, EsSalud and the Liga Contra el Cáncer expand free and mobile screening efforts.
• Clinicians highlight a shift to personalized care using tumor biology, genomic platforms, targeted therapies and immunotherapy, while emphasizing modifiable risks such as obesity and sedentary lifestyles.
