There is no medical proof on which drugs to take for faster recovery after breast cancer radiotherapy. For breast cancer patients after radiotherapy, it is necessary to consider further taking some endocrine therapy drugs such as tamoxifen and some targeted drugs such as trastuzumab for further anti-tumor therapy. However, the prerequisite for the application of endocrine drugs and targeted drugs is that after surgical treatment, the patient’s immunohistochemistry, suggesting that the estrogen receptor and Her-2 gene is positive. In this case, endocrine therapy and targeted drugs are effective, but tamoxifen and trastuzumab are not recommended for some patients who are negative for estrogen receptor and Her-2 gene. In addition, for patients with breast malignancy after radiotherapy, they can consume some protein powder, chicken, fish, beef, etc. in moderation, which is conducive to the supplementation of patients’ protein and the maintenance of patients’ immunity, and the emergence of consumptive body after radiotherapy further leads to a decline in the patients’ immunity. Patients should go to the hospital in time for examination and treatment under the guidance of the doctor.
