Enlarged lymph nodes of nasopharyngeal cancer mainly occur in the lymph node chain around the parasympathetic nerves, and the location of enlargement is mainly behind the angle of the mandible and below the back of the ear, and in the late stage, there may be enlarged lymph nodes in the front of the trachea and laryngeal area. Lymph node enlargement caused by nasopharyngeal cancer is relatively hard in texture, usually painless and itchy, and the location is usually the deep surface of the upper end of sternocleidomastoid muscle and below the back of ear. If lymph node enlargement occurs in this area, clinically it is mostly considered as one of the symptoms of nasopharyngeal cancer. In the middle and late stages of nasopharyngeal cancer, some nasopharyngeal cancer patients may have enlarged lymph nodes in the third and fourth regions and the opposite side, including the front of the trachea and the front of the larynx. When nasopharyngeal cancer has enlarged lymph nodes, it is recommended to go to the hospital in time for clear diagnosis and active treatment to avoid delaying the condition.
