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 you experience fatigue, weakness, or other discomforts after surgery, or if you are concerned about recurrence or metastasis, traditional Chinese medicine can be used to help restore bodily functions and enhance immunity. It is also advisable to engage in moderate exercise and maintain a positive mindset. Additionally, patients with breast cancer should pay attention to weight control and avoid becoming overweight.
