INTRODUCTION. It is known that the histopathological type of breast cancer exerts a strong influence on the prognosis of the disease and that there exists a direct correlation between this and the survival rates. The objective of this study was to evaluate the histopathological varieties associated with a good prognosis of the disease. METHODS. A retrospective, longitudinal, and descriptive study on the influence of the histological varieties on the good prognosis of breast cancer in patients operated on at "Dr. Mario Muñoz Monroy" University Hospital of Colón, Matanzas Province, from January 1976 to December 2007, was conducted. Of a total of 597 breast cancers attended in that period, 80 cases with "histological types of good prognosis" were taken. RESULTS. We found 23 non-invasive breast cancers, all of them with an elevated survival rate. 14 mucinous carcinomas were detected with 57 % of ganglionic metastasis, which was evidenced in the tumors over 4 cm of diameter. Ten cases of tubular and cribriform carcinomas (1.8 %) with an excellent prognosis were reported. 16 invasive papillary carcinomas were studied. In spite of their great size, no metastatic ganglia were found in the 168 analyzed.adenopathies. 17 medullary breast carcinomas were evaluated for an incidence of 2.85 % and a relatively favorable prognosis. CONCLUSIONS. All these histopathological varieties, excepting the non-invasive, had common invasive characters, well delimited margins and an excellent prognosis after the surgical treatment.
