Patients with stage I/II have a higher chance of radical resection, so there is no objection to surgical treatment. For stage IIIA patients, careful consideration should be made depending on the patient’s age, functional status of body organs, and assessment of lung function. Surgical treatment for lung cancer: The surgical method depends on the size of the tumor, the location of growth and the patient’s health condition: 1.Wedge resection: non-anatomical resection of a part of the lung 2.Segmental lung resection: anatomical resection of the segmental structure of the lung lobe with less damage than lobectomy 3.Lobectomy: anatomical resection of the complete lung lobe 4.Total lung resection: anatomical resection of the entire lung 3. The impact of surgery on the body: 1.Traditional open-heart surgery: about 20cm, recovery 7-9 days to discharge. 2.Thoracoscopic minimally invasive surgery: small wound, faster recovery, and shorter days of hospitalization. 3.Before surgery: quit smoking and practice doing deep breathing exercises. 4.After surgery: there will be a drainage tube left in the chest cavity to promote the early discharge of gas and fluid retained in the chest cavity.
