RESUMO:

In the clinical routine of veterinary medicine, breast tumor is the most prevalent neoplasm among canine females, the incidence of malignancy is high, about half of all histopathological diagnoses. Studies regarding breast cancer in animals is of great importance, since it is an oncological disease that affects a large number of bitches in the clinical-surgical routine. Knowledge of the pathophysiology of a disease is essential if it is to be successful in its diagnosis, treatment and prevention; with this, several studies were conducted reporting the predisposing factors of the disease. Tumor size, age, race, presence of regional metastasis or long distance are one of several factors leveraged. Thus, it is known that bitches between 8 and 12 years of age, not castrated before their 2,5 years of age, who used contraceptives during their reproductive phase, who have psychological pregnancy, may be one or more of the factors that More predisposed to breast cancer. Early diagnosis and the choice of the most appropriate therapy to resolve the disease increase the rate of cure in humans and animals. The treatment indicated as most suitable for this pathology is the removal of the tumor surgically, as determined by research in the area. Through the surgical technique of mastectomy, the entire mammary chain is removed along with the tumors, preventing the occurrence of neoplasia in other breasts, since there is lymphatic and arteriovenous communication between them. The surgery will only be used as a treatment in cases where there is no occurrence of long-distance metastases such as liver, spleen and lungs. Abdominal ultrasonography and chest radiography are recurrent complementary examinations requested by veterinary surgeons in patients diagnosed with breast neoplasm to confirm or not the presence of metastasis in distant organs. However, thoracic radiography does not detect metastatic nodules smaller than six mm. In the current literature, there are few studies comparing directly tumor size with malignancy, anatomical position and histopathological findings. In this context, with the aim of contributing to the control and prognosis of canine mammary neoplasia since the sample is large, this study proposes the performance of a work lasting a year and a half with the female patients of the canine species.  From the clinical-surgical routine of the veterinary hospital of the Federal Rural University of Rio de Janeiro, diagnosed with tumors in the breast. Tumor staging of treated dogs will be determined. Thoracic ultrasonography will be performed and treatment will be instituted according to the protocol previously established by the obstetrics sector in order to determine the relationship between tumor size, malignancy, anatomical location and histopathological findings. The identification of pulmonary metastases six mm with the accomplishment of the thoracic ultrasonography, will aid in the more correct choice of the oncological treatment. In this way, the obstetric service can standardize a therapeutic approach to patients with breast cancer with advanced characteristics prioritizing according to the results found, besides emphasizing the importance of the complementary examination thoracic ultrasonography, which is not routine in patients with cancer diseases.
