Thoracic tumors are not easily detected in early stage because of their insidious onset. No matter benign thoracic tumors or malignant thoracic tumors, the tumors are usually larger and more diffuse or have obvious symptoms when they are detected, and the patients are in poor condition. Of course, since most of the thoracic tumors are malignant and the overall treatment effect of malignant thoracic tumors is not ideal, whether it is malignant limited pleural fibroma or diffuse pleural mesothelioma, even through surgery, the survival period is only 9-24 months, we have to strive for early detection and active treatment to achieve certain effect. If it is a malignant thoracic tumor, it is a very serious category of disease because it is difficult to remove and the surgery is very difficult, so the treatment is also tricky and the effect is not ideal. Since thoracic tumor is a serious disease, when patients have persistent cough, ordinary anti-inflammatory treatment does not work well, or have difficulty in breathing or shortness of breath, they should go to the hospital in time and do not think it is a minor problem to delay treatment. If the tumor of chest can be found early and treated timely, it can still achieve certain effect.
