A hypothesis to relate salivary tumors with mammary and prostate neoplasias

Abstract

Salivary, mammary and prostate glands are sex hormone-dependent organs sharing common aspects in structure, hormonal responsiveness and tumor histopathology. Salivary tumors (especially the malignant types) are not as frequent as mammary and prostate neoplasias. Hence, prognosis of some salivary tumors is not always efficient. Here, we review the oncology of salivary gland and its putative relation to breast/prostate tumors.
