Whether a lymph node needs to be biopsied is not just based on size, but also takes into account the location, shape, hardness, tenderness, etc. Biopsy is recommended if the other features are not obvious and greater than 1 cm.
Whether a lymph node is recommended for biopsy also depends on the patient’s specific situation, and is usually considered from a variety of aspects, such as toughness to the touch, hardness, irregular shape, lack of pain, poor mobility, multiple occurrence, faster growth over time, in the vicinity of the primary disease such as a tumor, and in the vicinity of a common metastatic site.
Therefore, it is not rigorous to judge whether a biopsy is needed just by the size of the lymph nodes, but if there is no other obvious abnormality, and the lymph nodes are enlarged more than 1 cm, and there is no tendency for them to become smaller, it is recommended that lymph node biopsy be performed.
