Histological Classification in Canine Mammary Tumors: Back to Basics

Abstract

Histopathological examination of a tumor is essential, and all neoplasms must be diagnosed microscopically, which means that all the histological features from the tumor must be taken part to reach the final diagnosis [1]. This evaluation allows us to infer prognostic factors that must be considered basic in the thera-peutic orientation of these lesions. Additionally, it has been well described that breast cancer and canine mammary tumors share similarities regarding morphology and biological behavior.
