Multiple lymph node shadows refer to the situation of multiple lymph nodes appearing in one place at the same time, which is not necessarily cancer metastasis, but may also be related to lymphadenitis, tuberculosis infection and other diseases. 1. Lymphadenitis: this is a common inflammatory lesion, mainly caused by local tissue infection or inflammation of lymph nodes, and the main symptom of patients after the onset of the disease is multiple lymph node shadows. 2. Tuberculosis infection: Tuberculosis infection may also cause lymph node hyperplasia, which leads to multiple lymph node shadows. 3. Cancer metastasis: if the patient suffers from a certain kind of cancer and has metastasis, it may also cause multiple lymph node shadows, such as lymphatic metastatic cancer. When patients have multiple lymph node shadows, they should carry out further examination in time to judge the texture of lymph nodes, so as to confirm the diagnosis of the disease, and then choose suitable treatment methods under the guidance of doctors, such as conservative treatment, surgical treatment and chemotherapy.
