For breast cancer patients, endocrine therapy and radiotherapy are both commonly used treatments, and it is impossible to compare the effect of one treatment mode with the other, but the best treatment method is the one that suits the patient. Endocrine therapy is relatively mature and successful in the treatment of breast cancer, and when the indications are properly selected, the efficacy obtained is not worse than that of chemotherapy; in addition, endocrine therapy also has the advantages of fewer toxic side effects, which is favorable to consolidation of treatment, and the quality of life of patients during the period of treatment is also relatively high. Radiotherapy plays an important role in the treatment of all stages of breast cancer, which can not only be used as the main treatment for radical treatment of breast cancer, but also can be used as the auxiliary treatment after radical surgery for breast cancer. As the condition of each breast cancer patient is different, the treatment modality used by the patient will be different to a certain extent, and most of the breast cancer patients need to combine multiple treatment means for comprehensive treatment of the disease in order to get a better therapeutic effect, so the therapeutic effect of endocrine therapy and radiotherapy cannot be judged solely. Therefore, it is not possible to judge the therapeutic effect of endocrine therapy and radiotherapy alone. It is recommended that patients communicate with their doctors in time, choose the appropriate treatment method according to their own conditions, and take active treatment in order to avoid delays.
