Lung cancer without metastasis can be treated. Lung cancer without metastasis means that there is no metastatic spread of lymphatic system and distal organs, which mostly indicates that lung cancer is in early stage and the cure rate is still relatively high. Patients can recover after complete resection of the lesion through radical surgery; if there is a high risk of recurrence or metastasis, patients’ survival can be prolonged through postoperative adjuvant treatment. However, patients may still have recurrence after surgery, so they need to have regular follow-up examinations according to the doctor’s instructions, and at the same time take good care of themselves and maintain good living and dietary habits in order to reduce the recurrence rate; and if symptoms of recurrence appear, take targeted treatment immediately.
