Lymph liquefaction and necrosis are not necessarily cancer, some benign acute suppurative lymphadenitis may also have liquefaction and necrosis inside the lymph nodes, which may also be combined with fever and pain inside the nodes when touched, and require anti-infection treatment with antibiotics. And most of them require incision of the lymph nodes to drain out the liquefied, necrotic pus inside. If only antibiotic treatment is given, the inflammation is usually not well controlled. In the case of lymphoma or metastatic lymph node cancer, there is also a possibility of rupture or liquefaction and necrosis inside the lymph node when it grows bigger, and the treatment plan is usually formulated accordingly to the pathological type of the malignant tumor.
