Lymphoma generally refers to enlarged lymph nodes. There are many reasons for lymph node enlargement to change slowly from stiffness to softness, which may be due to inflammation subsiding, suppuration and other reasons, or malignant tumor getting better. 1. Inflammation subsides: swollen lymph nodes may be caused by bacterial or viral infection of lymphadenitis, initially manifested as a hard texture, pain, swelling, if the stiffness slowly becomes soft, may be due to inflammation subsides, generally do not need to worry about it, continue to cooperate with the treatment can be. 2. Suppuration: when the swollen, stiff lymph nodes slowly become soft, we also need to consider the aggravation of the infection, that is, the lymph node enlargement develops into suppurative lymphadenitis, usually due to the poor control and treatment of lymphadenitis, in this case, the local pain will be aggravated, and suppuration of the enlarged lymph nodes occurs. 3. Malignant tumors get better: some malignant tumors are prone to lymph node metastasis or directly invade lymph nodes, which is manifested as enlarged and hard lymph nodes. After effective treatment, the tumor cells in the lymph nodes gradually disappear and the texture can be returned to normal.
