Early stage breast cancer can be cured. The overall cure rate of breast cancer is very high, not only for early stage breast cancer, but also for progressive breast cancer, because the treatment effect of breast cancer surgery is more complete, and after surgery, there are many drugs available to treat the tumor, including targeted therapy drugs, immunotherapy drugs, and endocrine therapy drugs, etc. In addition, the size of early stage breast cancer is relatively small and there is no lymph node metastasis, so basically there are very few remaining tumor cells after surgery. If patients have regular review or combine with other drugs, the overall survival is high and many patients can achieve clinical cure.
