Background: in recent years, there has been an increase of breast cancer survival, due to the screening programs, advances in treatments and   prognostic factors identified, which play an important role. Objective: to determine breast cancer survival as well as factors that influence in it. Method: a descriptive-longitudinal study of population survival was carried out in Granma province from 1997 to 1998. The universe of study was based on the cases with breast cancer diagnostic. The survival was analyzed by the SPSS program 15.0 for Windows.  For the survival calculation was applied the Kaplan Meier method, the Long Rank test to compare the curves, the Cox Regression for multivariate analysis. Results: patients with late diagnosis triple the risk of dying, tumors size bigger than 2 cm or positive ganglions double the risk, the undifferentiated tumors and those who only received neoadjuvant treatments, increase it by seven times. Conclusions: early diagnosis, clinical stage, the size of the tumor, ganglionic status, histological grade and the therapeutic conduct constituted prognostic factors of breast cancer.
