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.
