Multiple lymph nodes in the right side of the neck for two years are of no great consequence if they are benign lesions. If it is a malignant lesion, it may cause health damage and threaten life. 1. Benign: if there are multiple lymph nodes in the right neck for two years, if the size of the lymph nodes is small, the edge of the lymph nodes is clear and the mobility is good, then it belongs to benign lesions, which may be caused by short-term dietary stimulation or long-term mental stress, or chronic lymphadenitis or tuberculous lymphadenitis, which can be restored to normal after effective treatment. 2. Malignant: If the edge of the lymph node itself is not clear, and there is adhesion with the surrounding tissues, and the mobility is poor, then we need to consider the possibility of malignant lymph node lesions. They are mostly caused by lymphatic metastasis of malignant tumors or lymphoma, and need to be examined as early as possible and treated actively after clear diagnosis. After the appearance of long-term lymph nodes, it is recommended to go to the hospital for CT or ultrasound examination, to determine its benign and malignant before targeted treatment.
