Lymph node metastasis may have the following symptoms: First, enlarged lymph nodes may be found in several places on the body, and sometimes the lymph nodes may be red, swollen and painful. Second, fever, some patients may have elevated body temperature, even chills and high fever. Third, some patients may experience progressive wasting and anemia. When obvious abnormality of lymph nodes is found, it is necessary to go to the hospital as soon as possible to improve relevant examinations, such as blood routine, C-reactive protein, tumor markers, ultrasound or CT, etc. If necessary, puncture biopsy or excision biopsy of lymph nodes is also needed. If only inflammatory cells are found in the lymph nodes, there is no need to worry too much at this time. If malignant tumor cells are found, lymph node metastasis is often considered. After lymph node metastasis is found, active treatment such as surgery, chemotherapy, targeted drug therapy, Chinese medicine treatment, etc. is needed.
