Determinants of survival in women diagnosed with breast cancer between 2008 and 2017: An analysis of a cohort using data from four Population-Based Cancer Registries of Colombia.

Background: Breast Cancer (BC) is the leading cause of cancer-related mortality in women, especially in low- and middle-income countries. Population-Based Cancer Registries (PBCRs) play a crucial role in monitoring cancer trends and guiding evaluation and planning of cancer control programs. In Colombia, there are no national analyses of BC survival.
