Abstract

Introduction: In recent years, it has been found a significant increase in the incidence of human neoplasias worldwide, which is also one of the main causes of morbidity and mortality in pets, highlighting the mammary tumors as neoplastic process that most affects our animals.

Objectives: To analysis of the current paradigm of neoplasias in pets; Promoting awareness of tutors and professionals of the animal health team for a more assertive management, in particular with regard its detection and early exeresis.
Methods: Retrospective study contemplating a sample of dogs (n=20) and cats (n=12) with mammary masses submitted to surgical excision and histopathological diagnosis.

Results: In the analyzed sample, was observed a higher frequency of breast neoplasms in dogs of undetermined breed and Common European breed cats, with the mean age, for both species, close to 10 years of age. There was also a higher frequency of malignant breast neoplasms, 75% in bitches and 66.7% in the cats, in relation to the benign ones.

Conclusions: It was possible to verify that, in the region of the country contemplated in this study, more malignant mammary neoplasms were diagnosed than benign ones, probably motivated by the late surgical excision of large mammary masses, sometimes ulcerated.
