Early breast cancer hormone receptor positive and postmenopausal

Early breast cancer that is hormone receptor–positive in postmenopausal individuals refers to invasive mammary carcinoma confined to the breast and regional lymph nodes (typically stages I through IIIA) in women who have undergone the permanent cessation of ovarian function In this postmenopausal demographic, the primary source of endogenous estrogen shifts from the ovaries to the peripheral aromatization of adrenal androgens in tissues such as adipose and liver, defining a key physiological vul...

The condition affects the breast parenchyma and regional lymphatic system, with tumor growth predominantly driven by the binding of circulating estrogen or progesterone to cellular receptors Pathophysiologically, the tumor cells express estrogen receptors, progesterone receptors, or both, making them dependent on hormonal signaling pathways for cellular proliferation and survival In this postmenopausal demographic, the primary source of endogenous estrogen shifts from the ovaries to the peripher...
