Enlarged mediastinal lymph nodes can be determined to be benign by size, number, texture, border, activity, and pain.
1. Size: The size of benign lymph nodes is usually smaller than that of malignant lymph nodes, which is due to the proliferation of malignant tumor cells in malignant lymph nodes, which can be larger.
2. Number: The number of benign lymph nodes is generally smaller than that of malignant lymph nodes because the lesions are relatively limited in extent and do not affect other locations.
3. Texture: Benign lymph nodes are relatively soft and malignant lymph nodes are hard.
4. Boundary: Most benign lymph nodes are clear and have smooth edges; malignant lymph nodes have unclear boundaries and rough edges.
5. Activity: most benign lymph nodes can be pushed; malignant lymph nodes may be adhered to the surrounding tissues and are difficult to be pushed.
6. Pain: benign lymph nodes have pain and pressure; malignant lymph nodes mostly have no pain.
Patients with enlarged mediastinal lymph nodes should go to the hospital in time for examination and treatment under the guidance of doctors.
