The patient is currently staged as stage II (T2N1M0), and the standard postoperative treatment should be chemotherapy. There are more chemotherapy drugs available for breast cancer, so it is recommended to consult a specialist again to avoid the original chemotherapy drugs. Mucinous carcinoma is better differentiated and can not be treated with postoperative adjuvant radiotherapy. The purpose of Chinese medicine treatment, like chemotherapy, is to prevent recurrence and metastasis, and also to improve the patient’s symptoms and quality of life. I have no experience and information on this subject to answer whether I can take pine pollen or not. In fact, the treatment of tumor should be multidisciplinary and comprehensive, including the combination of Chinese and Western medicine, in order to improve the efficacy as much as possible. The choice of endocrine therapy for breast cancer is mainly based on the patient’s receptor (ER, PR) status, age, hormone level, etc. It is difficult to say clearly in a few words. If possible, it is recommended to find a specialized oncology hospital to recheck the immunohistochemical index of tumor pathology (with paraffin specimens). If the ER result is (-) or (+/-), I personally recommend not to use endocrine therapy. If the ER result is (-) or (+/-), I personally suggest not to use endocrine therapy. The patient has a higher possibility of cure and it is recommended to standardize the treatment under the guidance of oncologist.
