Tamoxifen and radiotherapy are not absolutely good or bad, it mainly depends on which program the patient is suitable for. Tamoxifen is an anti-estrogen endotherapy drug, which can reduce the reproduction and proliferation of breast cancer cells by competing with estrogen, and play an anti-cancer effect, and it is mostly used for advanced ovarian cancer and advanced recurrent endometrial cancer that is ineffective in chemotherapy. Radiotherapy, on the other hand, is more widely used, and can be used in early, middle and advanced stage patients, and can also be used as a postoperative adjuvant treatment program, mostly in cancers with higher sensitivity to radiotherapy. There is no absolute advantage or disadvantage of tamoxifen and radiotherapy for different types of pathologies and conditions, it depends on which option is suitable for the patient, and can be used simultaneously if necessary.
