May 11, 2021 · ER-positive: Breast cancers that have estrogen receptors are called ER-positive (or ER+) cancers. PR-positive : Breast cancers with progesterone receptors are called PR-positive (or PR+ ) cancers. Hormone receptor-positive : If the cancer cell has one or both of the receptors above, the term hormone-receptive positive (also called hormone-positive or HR+ ) breast cancer may be used.
People with ER-positive breast cancer typically have common breast cancer symptoms, including: A change in the size, shape or contour of your breast. A mass or lump, which may feel as small as a pea. A lump or thickening in or near your breast or in your underarm that persists through your menstrual cycle. A change in the look or feel of the ...

All breast cancers are examined under a microscope for biomarkers of estrogen and progesterone receptors. About 70% of breast cancers are hormone receptor-positive. Your hormone receptor status should appear on your pathology report after biopsy or surgery. Receptors will be retested if you ever have a recurrence or metastasesas well, as your statu...
Your report will show the percentage of cells that tested positive for hormone receptors.Zero percent means no receptors were found and 100 percent means all the tested cells had receptors.
Breast cancers that are estrogen receptor-positive (ER+) and/or progesterone receptor-positive (PR+) are "fueled" by hormones. They're different from breast cancers that are HER2-positive, in which tumor growth is driven by growth factors that bind to HER2 receptors on the cancer cells. Breast cancers that don't have any of these receptors are call...
If your tumor is ER+ and/or PR+, hormonal therapy is usually recommended.The choice of medications, however, depends on your menopausal status. Before menopause, the ovaries produce the greatest amount of estrogen. To prevent this estrogen from fueling your cancer cells, medications called selective estrogen receptor modulators are used. These drug...
