Introduction: Estrogen receptor status helps guide breast cancer treatment. Estrogen receptor-positive (ER-positive) tumors express (have a lot of) estrogen receptors. Estrogen receptor-negative (ER-negative) tumors do not express (have few or no) estrogen receptors. ER-positive breast cancers can be treated with hormone therapies such as tamoxifen, aromatase inhibitors and ovarian suppression. Breast cancers that are ER-positive tend to be PR-positive. And, cancers that are ER-negative tend to be PR-negative. Sometimes, a breast cancer is ER-positive, but PR-negative. Because current hormone therapies are designed to treat ER-positive cancers, these cases are treated the same as breast cancers that are positive for both hormone.
