The second stage of lung cancer can be treated by combined treatment, including surgery, which is one of the main treatment methods for lung cancer if the patient’s functional status and stage of the disease are appropriate. Surgery for lung cancer can be divided into two types: radical and palliative, which may require combined treatment with radiation therapy, targeted chemotherapy, and Chinese herbal medicine, etc. Combined treatment can control the further spread and metastasis of cancer cells and play an important role in improving the resistance and quality of life of cancer patients. The specific treatment plan needs to be evaluated in conjunction with the pathological stage, extent of invasion, lesion location and other factors before receiving standardized treatment.
