How long to have chemotherapy after breast cancer surgery depends on individual patient’s condition and cannot be generalized. Usually, chemotherapy is carried out about 1 month after breast cancer surgery, most patients have basically recovered from the surgical wound, their physique has been improved and cancer cells are basically controlled. At this time, chemotherapy further eliminates some cancer cells in the blood to avoid cancer cells causing recurrence or metastasis, which is more effective. However, whether to start chemotherapy or not needs to be based on patient’s specific situation. If the patient has larger tumor and more lymphatic metastasis, chemotherapy should be carried out as early as possible after surgery to avoid more metastasis. If the patient has poor physical recovery, poor condition or fever after surgery, the time to start chemotherapy needs to be extended appropriately. After breast cancer surgery, patients should listen to medical advice, take more rest and prevent wound infection. Pay attention to supplement nutrition, you can eat more black fungus, mushrooms, etc. Avoid straining and catching cold, adjust your mentality and face it positively.
