The survival curves of the variables were compared using the log-rank test which were statistically significance (p<0.05). Results: The mean time to death is approximately 51.1 months. Women aged ≤ 50 years and of white race/color presented the worst survival. Conclusion: We found out that age, race/color affect specific survival and there is a need for reviewing the control plan for breast cancer in order to increase the survival of women diagnosed with this pathology.
