About 80% to 85% of breast cancers are hormone receptor positive. These hormone receptors include Estrogen Receptor (ER) and Progesterone Receptor (PR). In general, most post menopausal women are hormone receptor positive. Of the 15% patients of breast cancer who will be ER/PR negative, majority tend to be premenopausal patients.
