Introduction: The research in breast cancer has been focused in the study of the biological and immunohistochemically characteristics, as elements for prognostic factors of disease free survival and overall survival and as predictive elements in response to therapies. This study describes the clinical and pathologic features of patients treated for breast cancer in a breast unit in Medellin during the years 2006-2013. Methods: A descriptive and retrospective trial was performed evaluating variables from medical records of breast cancer patients who attended a breast cancer unit in Medellín, Colombia between January 2006 and June 2013. Results: There were 1,480 cases of breast cancer patients, with mean age of 54 years old. In situ carcinoma was diagnosed in 10 %, and invasive carcinoma was diagnosed in 83%; 80% of the cases was carcinoma non-specified type, invasive lobular carcinoma 7% and special types 3%. Estrogen receptor was positive in 73%, progesterone receptor was positive in 64% and HER 2 neu was positive in 15%. Early stage breast cancer was observed in 32%, locally advanced in 48% and metastatic stage in 3% of the cases. In 7% of the cases did not found information about this. 11% of the patients had conservative breast surgery (BCS) plus sentinel lymph node biopsy (SNB) and 7 % had BCS with axillary lymph node dissection (ALND). 58% had simple mastectomy plus SNB and of these patients, 5% had immediate reconstruction. 15% had modified radical mastectomy (MRM) and 7% of these patients had immediate reconstruction. In 65% adyuvant chemotherapy was performed and in 57% had adyuvant radiotherapy. Adyuvant endocrine therapy was received by 63% specially with Tamoxifen. Conclusions: The results of this study allows more detailed approach to the biological aspects of cases of breast unit of Colombia awareness and highlights the necessity for implementation of clinical and imaging strategies to diagnose greater proportion of breast cancer in early stages in our women population.
