ER-positive is one of the Receptor statuses identified in the classification of breast cancer.Receptor status was traditionally considered by reviewing each individual receptor (ER, PR, her2) in turn, but newer approaches look at these together, along with the tumor grade, to categorize breast cancer into several conceptual molecular classes [1] that have different prognoses [2] and may have ...

Estrogen deprivation therapy, also known as endocrine therapy, is a form of hormone therapy that is used in the treatment of breast cancer.Modalities include antiestrogens or estrogen blockers such as selective estrogen receptor modulators (SERMs) like tamoxifen, selective estrogen receptor degraders like fulvestrant, and aromatase inhibitors like anastrozole and ovariectomy.
When a tumor is “triple positive,” that means that its growth is fueled by both estrogen and progesterone hormones, as well as a protein called human epidermal growth factor receptor 2 (HER2).
TNBC is hard to treat because, unlike many other breast cancers, the tumor cells do not have estrogen or progesterone receptors, and do not make a protein called HER2. They, therefore, do not ...

Endocrine therapy for breast cancer involves selective estrogen receptor modulators (SERMS), such as tamoxifen, which behave as ER antagonists in breast tissue, or aromatase inhibitors, such as anastrozole. ER status is used to determine sensitivity of breast cancer lesions to tamoxifen and aromatase inhibitors. [27]
