Lymph node examination method

There are many methods for lymph node examination: the first one is the most commonly used physical examination by doctors. Usually, doctors touch lymph nodes and preliminarily judge whether the lymph nodes are benign or malignant according to whether the texture of the lymph nodes is good, whether they are fixed with surrounding tissues, and whether there is tenderness. Generally speaking, lymph node metastasis of malignant tumor usually presents as a hard, relatively fixed, tenderness free lymph node mass. The second inspection method is to use B-mode ultrasound to determine the high echo or low echo of lymph nodes and the surrounding blood supply. Generally speaking, if the blood supply is good and high echo, it is usually benign or inflammatory lymph nodes. The third method is lymph node biopsy. Resection of local lymph nodes for pathological examination after local anesthesia is the gold standard for diagnosis of benign or malignant lymph nodes.
