Guidelines for International Breast Health and CancerControl–Implementation

Breast Cancer in Latin AmericaResults of the Latin American and Caribbean Society of Medical Oncology/BreastCancer 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

Cancer 2008;113(8 suppl):2359–65. 2008 American Cancer Society

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
