It is estimated that, by the year 2020, 70% of patients with cancer will live in countries that have less than 5% of the resources available for care of patients with cancer.1 Breast cancer is the most common malignancy in women worldwide and is a prototype of global cancer disparity. While breast cancer mortality is decreasing in developed countries, it continues to increase in low- and middle-income countries (LMCs). The age-adjusted survival rate from breast cancer ranges from 32% in sub-Saharan Africa to 81% in the United States.1 This disparity results from several factors, mostly related to disease biology and access to screening and effective treatments.1
