For patients with lung cancer, comprehensive treatment based on surgical resection is the preferred treatment option whenever feasible. However, due to the lack of understanding of lung cancer treatment, there are three misconceptions, which should be clarified here: 1. Surgery and anesthesia are admittedly a blow to elderly patients, and if they are coupled with excessive lung tissue removal and failure to protect lung tissue and lung function, the quality of life of patients will be affected to a certain extent. However, as long as the preoperative evaluation is done carefully and the principle of “maximum tumor removal and maximum lung tissue preservation” is followed to ensure complete tumor removal and as much lung function preservation as possible, surgical treatment is feasible and safe. 2. It is thought that surgery is not suitable for elderly patients. In essence, whether surgery can be performed or not, more consideration is given to the physiological age of the patient rather than the actual age. As long as the patient’s physical condition, especially cardiopulmonary function, can tolerate surgery, no matter how old the patient is, surgical treatment can be chosen, and thoracoscopic surgery with less trauma, less loss of lung function to the patient and fewer postoperative complications is optimal. Chinese medicine has certain auxiliary effects in the treatment of lung cancer, especially in improving patients’ physical quality, increasing immunity and improving tolerance to surgery, radiotherapy and chemotherapy. However, Chinese medicine should not be considered as the main treatment. Because so far, there is no definite evidence to prove that a single dose of Chinese medicine can cure lung cancer.
