Lung nodules do not need to remove the lungs, because lung nodules are divided into benign nodules and malignant nodules, especially for benign lung nodules, no obvious symptoms, you can follow the diagnosis and observation; and malignant nodules of the lungs, also need to improve the examination, to clarify the specific stage and type, to take relative treatment measures, and do not need to remove the lungs. Clinically, the more common lung nodules are benign nodules, for this type of nodules, most do not need to carry out surgical treatment, not to mention the lungs can not be removed. Especially for patients who do not have obvious symptoms such as cough and chest pain, they can be reviewed regularly and do not need to be treated. For malignant nodules in the lungs, further examination is needed to clarify their specific stage and typing, for example, small cell carcinoma patients are mainly treated with radiotherapy and chemotherapy (cisplatin, etc.), while non-small cell lung cancer patients can be treated with surgery, radiotherapy, chemotherapy (cisplatin, etc.), and molecular targeting therapy (erlotinib, etc.), etc. Surgery can be used to resect the diseased segment of lungs, but not to resect the lungs completely. Surgery can remove diseased lung segments, but it cannot completely remove the lungs. Lungs are the respiratory organs of human body, after removing the lungs, the respiratory function will be affected. Generally speaking, if the tumor is completely removed, as much as possible the lung tissue should be preserved; if there is any lung nodule, it is recommended that the patient should go to the clinic for checking and clarifying the condition, and the medication needs to be used under the guidance of the professional doctor.
