Control–Implementation
Breast Cancer in Latin America
Results of the Latin American and Caribbean Society of Medical Oncology/Breast
Cancer Research Foundation Expert Survey
---------------------------------------------------------------------------------------------------
The incidence of breast cancer in Latin American countries is
lower than that in more developed countries, whereas the mortality
rate is higher. These differences probably are related to differences
in screening strategies and access to treatment.
Population-based data are needed to make informed decisions

10. Currently, there are enormous differences in healthcare
expenditures between developed and developing countries;
developed countries spend nearly 10% of their gross domestic
product on healthcare, whereas poorer countries spend 5% to 6%
or less
Greater than 90% of countries had no national law or guideline
for mammography screening. The access rate to mammography
was 66.3% at the country level and 47% at the center level
