Tumores de mama en animales de compañía: la importancia de prevenir

Abstract

The appearance of neoplasms in domestic species is increasingly frequent and "many statistics in veterinary medicine show cancer as the first cause of death in pets, hence the importance of better understanding its biology" (Mouly, 2014, p. 351). Breast tumors are one of the most frequent tumors in canine females and, taking both sexes into account, they are the second most common group, behind skin tumors; (Cartagena Albertus, 2011) and the third group in cats, after lymphomas and skin neoplasms (Soriano Fita, 2015). That is why I find it interesting to discuss this pathology in this report and highlight the influence that female sex hormones have on the incidence of presentation and how early sterilization prevents them, especially since there are still many people who believe that to castrate your pets, they must have reached a certain age or that they must have at least had a young. This bibliographic review, apart from developing the pathology in canines and marking some differences with felines, includes a description of the anatomy, development and histology of the mammary gland and generalities about neoplasms, in order to help understand a little plus the biological behavior of mammary tumors. It also reports a clinical case treated at the HEMeVe (Veterinary Medical School Hospital) during the OPP (professional practice orientation) held during 2019.
