What is the risk of pulmonary mediastinal lymphadenopathy?

The harm of mediastinal lymph node enlargement is directly related to the cause of mediastinal lymph node enlargement. Sometimes mediastinal lymph node enlargement is only a sequela left over from pulmonary tuberculosis, which normally does not cause clinical symptoms and does not cause some adverse consequences. It does not need to be treated. In this case, mediastinal lymph node enlargement is not harmful. However, mediastinal lymph node enlargement may also be lung cancer, showing mediastinal lymph node metastasis. For this situation, it often represents that the disease is more severe, and even surgical resection is more difficult. The patient's recovery will be worse, and the survival period may be shorter. Mediastinal lymph node enlargement may also be malignant lymphoma. If this is the case, the patient's outcome is also worse, and the survival period is relatively short.
