cells in the breast grow uncontrollably, forming
tumors that can spread to other parts of the
body if untreated. It is the most commonly
diagnosed cancer among women worldwide.
Global Burden (2024): An estimated 2.4
million women were diagnosed, and 694,000
died from the disease. 7 10

survival is 77.8%, but this varies drastically
by region. High-income countries see 87.3%
survival, compared to 41.9% in low-income
countries.Risk Factors: Female gender is the strongest
factor. Others include increasing age, obesity,
alcohol use, and family history (e.g., BRCA1/
BRCA2 gene mutations). However, roughly
80% of cases occur in women with no
specific risk factors other than sex and age. 7
