Postoperative breast cancer pathology HR (+) means that both estrogen receptor (ER) or progesterone receptor (PR) are positive, and the pathology report often suggests that it is ER (+) or PR (+), which is one of the most common immunohistochemistry of tumors in breast surgery. In clinical practice, it is generally believed that breast malignant tumors in patients with HR (+) are related to estrogen and progesterone in the body, and usually require endocrine therapy, which aims at reducing the level of estrogen and progesterone in the patient’s body so as to achieve the therapeutic effect. Pathologic examination after breast cancer surgery is very important to guide the clinician’s treatment plan. However, the treatment of breast cancer requires comprehensive treatment in many aspects, and there are individual differences in the treatment plan, so you should go to regular hospitals to find a professional doctor for consultation.
