Chemotherapy is generally not required for ductal carcinoma in situ, as the tumor cells typically do not breach the basement membrane of normal cells and are mainly confined within the ducts, without spreading or metastasizing. Therefore, clinical cure is usually achieved after surgical resection. If patients experience fatigue, weakness, or other discomforts after surgery, or if they are concerned about recurrence or metastasis, traditional Chinese medicine can be considered to help restore bodily functions and enhance immunity. Regular moderate exercise and stress relief are also recommended. Additionally, breast cancer patients should pay attention to weight management and avoid becoming overweight.
