Malignant tumors on the pleura can be treated by surgery, medication, radiation therapy, etc. The use of medication should follow the doctor’s instructions. 1. Surgery: For patients with pleural malignant tumors, if they can be detected and diagnosed early, and the malignant tumors can be widely resected through surgery as early as possible, their recovery will be greatly improved. 2. Drug therapy: after surgical resection, chemical drug therapy can be used in combination. Chemical drugs such as cyclophosphamide can be injected intravenously or directly into the pleural cavity. 3. Radiation therapy: for pleural malignant tumors that cannot be removed by surgery, radiation can be used to kill and exterminate malignant tumor cells. It is important to note that when a suprapleural malignant tumor is found, one should actively seek medical treatment to avoid delaying the condition.
