Introduction: In past years the conservative surgery became consolidated as a valid procedure in treatment of a determined group of breast cancer patients, thus allows to achieve a satisfactory local control with a lesser level of mutilation, neither modifying the survival nor distant metastasis index from a distance. Objective: To determine the results of conservative surgery of breast cancer according to the variables selected during 1991-2009. Methods: a longitudinal and retrospective study was conducted in women diagnosed and treated due to breast cancer who underwent conservative surgery (n=77), fulfilling the established inclusion and exclusion criteria. Data descriptive analysis was performed by absolute and relative frequency distribution. The estimation of global survival curves and free of relapse was performed by Kaplan-Meier method. Results: The 40 to 59 age group was the predominant one for a 67.6 %. Only the 10.4% of patients had first line positive backgrounds of breast cancer. The IIA clinical stage predominates with a 54.5 % and the more frequent histological type, the infiltrating ductal carcinoma for a 84,4 %. The 5-years global survival for our patients was of 95 % and the interval free relapse was of 87.5 %. Conclusions: Our results not differ from those found in studies at world level.
