Mediastinal tumors often develop silently and are difficult to detect. Most cases of mediastinal tumors are discovered by chance during routine health check-ups or when the disease has reached a late stage. At this time, thoracic endoscopic surgery to remove small mediastinal tumors is necessary.

If a large mediastinal tumor is detected, the patient needs to be treated early to prevent the disease from having negative effects on the lungs and surrounding organs. In particular, thoracic endoscopic surgery to remove a large mediastinal tumor (5cm) is one of the most optimal treatment methods today.

Thoracic endoscopic surgery to biopsy mediastinal lymph node tumors is a method with high safety during and after surgery, to obtain mediastinal lymph node tumor tissue samples for pathological examination.

Computed tomography helps to accurately determine the location, size, density of mediastinal tumors, the anatomical relationship of mediastinal tumors with surrounding organs, etc. Under the guidance of computed tomography, mediastinal biopsy techniques will be performed more easily and accurately.

Mediastinoscopy is an invasive surgical method that allows doctors to perform biopsies to perform additional diagnostic tests for mediastinal diseases, including mediastinal lymph nodes.
