Mammary tumors in male dogs are infrequent. They are the most commonly neoplasm in females. Due to limited reports and studies in veterinary, it can not be said about the incidence of mammary tumors in males. As seem in females, the etiology of mammary tumors in males is uncertain, but ...
28,29 Mammary tumors in male dogs are strongly positive for ER and show less expression of PR.33 In malignant tumors, ER and/or PR immunostaining is higher in complex and mixed histologic subtypes than in simple histologic subtypes and higher in papillary adenocarcinomas than in solid tumors.28...

In contrast, mammary tumors rarely occur in male dogs (Gamba et al., 2017). The mammary tumors diagnosis is always performed microscopically (Goldschmidt et al., 2017) and histopathological analysis of the tumor is essential to provide information of the tumor and when available, the sentinel ...

Cytologic examination of fine-needle aspirates from mammary gland tumors in the dog: diagnostic accuracy with comparison to histopathology and association ... Conclusions: Cytologic examination of mammary tumors in the dog has satisfactory accuracy, sensitivity, and specificity for the diagnosis of malign...
(C) In luminal breast cancers, oncogene expression leads to asymmetric perpendicular cell divisions that produce one polarized and one non-polarized daughter cell to generate a multilayered epithelium. Unequal proliferation leads to expansion of the non-polarized population to generate tumors that lack ...
could have been possibly observed. Although it cannot be excluded that mice treated at a higher age can be susceptible to mammary tumors, the window of susceptibility seems to be present in mice as well, as treating mice during the 4–10 weeks old period typically leads to a 40–70% tumor...
Mammary tumors are the second most common neoplasia in dogs. Due to the high similarity of canine mammary tumors (CMT) to human breast cancers (HBC), human biomarkers of HBC are also detectable in cases of CMT. The evaluation of biomarkers enables clinical diagnoses, treatment options and progn...
