Malignant lung mesothelioma can be operated. The cause of malignant pulmonary mesothelioma is currently not well understood, and is generally believed to be related to factors such as long-term exposure to asbestos, which is often manifested clinically by symptoms including chest pain, dyspnea, and coughing. There is no effective treatment for malignant mesothelioma, but the prognosis can be improved by surgery and chemotherapy. For patients with limited-stage malignant mesothelioma, radical surgery can be performed for resection. Control of mesothelioma pleural fluid (fluid that stays in the chest cavity) can be achieved by aspirating the pleural fluid (fluid that stays in the chest cavity) and fully separating the adhesions so that the lungs can be reopened, and then spraying in sterilized talcum powder to immobilize the pleural membrane, which can effectively control the production of pleural fluid and alleviate the symptoms of the patients. Malignant lung mesothelioma can also be treated with chemotherapeutic drugs according to the condition to kill tumor cells and control the progress of the disease, and common drugs include cisplatin. Patients with malignant mesothelioma should go to the hospital for consultation and treatment in time to avoid delaying their condition.
