The conservative treatment of the mammary gland has allowed support the success in the treatment of invasive cancer, without sacrificing the esthetic and functionality of the organ. Since March 1980 at the mastology unit “Clinica Leopoldo Aguerrevere” we followed patients with breast cancer T1 and T2, no bigger than 3 cm. 543 patients were divide in a first group of 295 patients from May, 1980 to December 1998, to which a partial oncological mastectomy was made by axillaries dissection of the levels I and II, and a second group from May, 1998 to December 2 204 with partial mastectomy and identification of the sentinel lymph node biopsy using a combined technique of tecnetium 99 and clear blue, and axillaries dissection when the sentinel node was positive. The average of age was 53.13 years and the most frequent clinical stage was I, being the tumor similar size in the both groups of study. The global survival of the total group was 85.5 % at 5 years and 68.5 % at 10 years. Free survival disease was 83.6 % at the 5 years and 63.2 % at 10 years.
