Chronic obstructive pulmonary disease (COPD) is a condition in which the airways are blocked slowly and for a long time. This condition causes lung function to gradually decline, manifested by increasing shortness of breath. This is a dangerous disease because the disease progresses in the human body for decades but the patient does not detect the disease. The progression of COPD is in only one direction, which is to get worse over time.

When detecting mediastinal cancer or benign mediastinal tumor, it is necessary to treat it early to avoid adverse effects on the lungs and surrounding organs.

Although a mediastinal tumor can be benign or malignant, if left untreated, it can cause lung complications and be life-threatening. Therefore, tumor resection is a necessary indication for the patient.
