What does Estrogen and progesterone receptor test mean?
These are tests done on the tumour sample removed during your breast surgery to find out whether or not the tumour is likely to be sensitive to hormones. In general, post-menopausal women are more likely to be estrogen receptor positive than pre-menopausal. The test helps your physician decide whether the tumour can be treated with some kind of hormonal therapy, like Tamoxifen.
