Hormone receptors types
WebBreast tumors may be positive for estrogen receptors (ER+), progesterone receptors (PR+) or both (ER/PR+). About 80 percent of all HR+ breast cancers are ER+ or ER/PR+. If a cancer cell is ER+, it means it can receive signals from estrogen instructing the cells to grow. If a cancer cell is PR+, these signals can come from the progesterone hormone.
