ERPOSITIVE Meaning and
Definition
-
ER-positive refers to a characteristic of certain types of cancer cells, particularly breast cancer. The term ER stands for estrogen receptor, which is a protein found on the surface of cells. ER-positive cancer cells have receptors that bind to the hormone estrogen.
In breast cancer, the presence of estrogen receptors indicates that the cancer cell growth is influenced by the hormone estrogen. This means that ER-positive breast cancer cells depend on estrogen to grow and multiply. The interaction between estrogen and the receptors on the cancer cells activates signaling pathways that promote cell division and tumor growth.
Knowing the ER status of breast cancer is crucial because it assists in planning appropriate treatment strategies. Cancer cells that test positive for estrogen receptors can be treated with hormonal therapies. These therapies involve reducing the levels of estrogen or blocking the binding of estrogen to the receptors, thereby inhibiting cancer cell growth.
ER-positive breast cancer tends to be less aggressive and more responsive to hormonal therapies compared to ER-negative breast cancer. Determining the ER status of breast cancer cells is typically done through laboratory testing of tumor samples obtained from biopsies.
Overall, ER-positive is an essential classification in breast cancer diagnosis as it helps guide treatment decisions and predict disease prognosis.
