Breast cancer is a malignant tumor, but it can be cured through active treatment, so it can survive for a long time. After breast-conserving surgery, other treatments such as chemotherapy, targeted drug therapy, endocrine therapy, radiotherapy, and herbal medicine are needed. After surgery, regular follow-up, such as breast ultrasound, mammogram, breast MRI, etc., should be carried out, and then appropriate treatment should be given according to the corresponding results, and actively adjusting the diet and increasing physical exercise can improve the body’s resistance and prevent tumor cells from metastasizing again, such as proper intake of fresh fruits and vegetables, low-fat, high-quality protein, and physical exercise. There are many kinds of physical exercises, such as jogging, swimming and Tai Chi.
