Mammary gland tumors in female dogs – correlations between clinical stage and prognosis

Abstract

mesenchymal tissue of the mammary gland. They are characterized by abnormal, autonomous, and progressive cell proliferation, frequently influenced by hormonal factors (estrogens and progesterone), with variable potential for local invasion and metastasis. During the research, the most frequent cases by age were recorded in females aged 10-12 years. In September, most cases occured in the 10-12 age group (43.75%) with 7 cases, followed by the 12-15 age group (31.25%) with 5 cases. Only 2 cases were recorded in both the 5-10 age group (12.5%) and 15-20 age group (12.5%), while no cases were recorded in dogs under 5 years of age. In October of the same study year, statistics showed that of the 20 cases diagnosed during the year, most were recorded in the 10-12 age group (9 cases, or 45.0%) and in the 12-15 age group (7 cases, or 35.0%), followed by the 5-10 and 15-20 age groups, with 2 cases each, or 10.0%.
