Lymph node metastasis becomes bigger in a few months, mostly because the tumor metastasizes to the lymph nodes and the tumor cells appear to grow and multiply again. Lymph nodes do not become smaller and smaller when malignant tumor metastasis occurs, and this condition will gradually increase in size when anti-tumor treatment is not carried out, because malignant tumor cells are transferred to the lymph nodes through lymphatic vessels and thus grow and multiply in the lymph nodes, resulting in the lymph nodes becoming bigger and bigger, and even the problem of necrosis or ulceration is formed. When lymph node tumor metastasis is found, it is necessary to find the primary lesion of the tumor, judge the pathological typing of the malignant tumor, and take reasonable treatment plan, but it is recommended not to overmedicate and not to take radiotherapy or chemotherapy treatment arbitrarily. If the tumor has lymph node metastasis, it is recommended to consult the general surgery department of regular hospitals, and standardize the treatment under the guidance of professional doctors, so as not to delay the condition.
