Morphological diagnostics of breast tumors in dogs

The prognosis of neoplasms in dogs and the protocol of postoperative treatment depend not only on the clinical stage of the disease, but also on the histological variant of the tumor, the degree of its differentiation and proliferative activity. Clinical manifestations of tumors with different morphological variants, different levels of differentiation and different types do not have fundamental differences, which in most cases does not allow predicting the outcome based on clinical examination data alone. Despite many proved positive results of X-ray and ultrasound studies in the diagnosis of various diseases of the breast, many questions remain unexplored. The development of mammary tumors in animals, in particular, dogs, is the most important problem of modern veterinary medicine. Therefore, timely diagnosis and treatment of dogs with mammary tumors requires a modern scientific approach and detailed study. The aim of the work was to develop morphological diagnostics, study the pathology of canine mammary gland tumors in order to form a database for the use in veterinary practice. The clinical part of the research was carried out in the conditions of veterinary clinics in Orel and Mtsensk (veterinary clinic "Harriot", veterinary office of Doctor Morozov, veterinary clinic "MC Doctor"). The analysis of the anamnesis data of the operated animals showed that mammary gland tumors are most often found in dogs over 5 years old. In their anamnesis (43%), there is a pathological course of pregnancy, complications during and after childbirth, a violation of the hormonal status, pathology of the uterus and mammary glands. The research results show that malignant breast tumors are much more common in dogs (77%) than benign tumors (23%).
