To determine whether breast cancer cells contain hormone receptors, doctors test samples of tumor tissue that have been removed by surgery. If the tumor cells contain estrogen receptors, the cancer is called estrogen receptor positive (ER positive), estrogen sensitive, or estrogen responsive.
Estrogen and progesterone hormone receptor (ER and PR) status tests are standard tests for all invasive breast cancers, and on recurring cancers, as recommended by guidelines published in 2010 by the American Society of Clinical Oncology (ASCO) and the College of American Pathologists (CAP).
