With hormone receptor-positive breast cancer, the cancer grows in response to the hormones estrogen and progesterone learn more about this type of cancer here. Hormone receptor-positive breast cancer about 80% of all breast cancers are “er-positive” that means the cancer cells grow in response to the hormone estrogen. Otherwise the test will say the tumor is hormone receptor-negative hormone receptor-positive (or hormone-positive) breast cancer cells have either estrogen (er) or progesterone (pr) receptors these breast cancers can be treated with hormone therapy drugs that lower estrogen levels or block estrogen receptors.

Discrepancies of the biochemical and immunohistochemical estrogen receptor assays in breast cancer fritz f parl, md, and yvonne f posey, md. Your pathology report will include the results of a hormone receptor assay, a test that tells you whether or not the breast cancer cells have receptors for the hormones estrogen and progesterone hormone receptors are proteins — found in and on breast cells — that pick up hormone signals telling the cells to grow. Hormone therapy blocks the tumor from using estrogen and/or progesterone for cancers that are er and/or pr positive, slowing or stopping tumor growth two types of drugs may be used one type called tamoxifen (nolvadex) can be used for women of all ages, while other types of drugs called aromatase inhibitors (ais) stop tissues and organs.

estrogen receptor assay positive Er-/pr+: about 2% of breast cancers are estrogen-receptor-negative and progesterone-receptor-positive this means that the hormone progesterone is likely to support the growth of this cancer only a small number of breast cancers test negative for estrogen receptors but positive for progesterone receptors.
