S100 can be used as a tumor marker in canine mammary tumors

According to Schmitt and Bacchi,[2] S-100 protein is also useful as a tumor marker in diagnostic immunocytochemistry. By recognizing and understanding the signatures of normal cells and how these become cancerous, technology can provide important insights into the etiology of cancer that can be useful for early detection, diagnosis, and treatment. [...]biomarkers could be an invaluable tool for cancer detection, diagnosis, prognosis, and therapy selection. [36] One of the advent laboratory diagnostic tools, immunohistochemistry, was used in this study, particularly in detecting S100 protein in mammary tumors. Since there had been challenges in diagnosing CMT, as a possible option to do immunohistochemistry in addition to the routine diagnostic method of hematoxylin and eosin staining for histopathology, this study could have a potential for further investigation for more precise diagnosis. [...]in the study of 10 classifications of CMT, immunohistochemical staining of S100 can be used as a marker in CMT.
