Resumen
Cancer is one of the main causes of death in dogs and cats and the mammary neoplasm
is one of the most frequent in these species. Although some studies have been performed,
there is little data on the epidemiology of this disease in cats. Thus, this study has, as primary
goal, to determine the most prevalent tumors in cats and to associate the mammary tumors to
some prognostic factors. The files from the Veterinary Pathology Laboratory of the
Universidade Federal de Santa Maria were reviewed. Between the years 2000 and 2011, a
total of 1427 feline cases including necropsies and biopsies were found. Based on the
collected data from these cases, a relation between mammary tumors and some factors such as
sex, age, breed, reproductive status, use of contraceptives, number and location of affected
glands, presence of ulcerations, size of the tumor, and presence and location of metastases,
was studied. Mammary tumors were the second most prevalent tumors (39,57%), after skin
neoplasms (41,49%). All feline tumors were in females, mostly older and Domestic Shorthaired
cats. Malignant neoplasms were the more frequently diagnosed (72,35%), followed by
non-neoplastic tumors (22,58%), and benign neoplasms (5,06%). The smaller tumors were
mostly carcinomas. Ulcers were observed in malignant tumors (92%) and non-neoplastic
tumors as well (8%). Distant metastases were found mainly in the lungs and skin.
