Cervical lymph node dissection may carry risks of vascular and nerve damage, pleural injury, and pneumothorax. Cervical lymph node surgery carries certain risks; cervical lymph nodes, if deep, are surrounded by abundant blood vessels and nerve tissue. Some lymph nodes remain attached to these tissues, and a little carelessness during surgery may damage blood vessels and nerves. In addition, cervical supraclavicular lymph nodes are also adjacent to the top of the pleura, which can lead to pleural injury and pneumothorax. Enlarged lymph nodes are usually treated by surgery or medication. Surgical techniques are now mature, with relatively good results and low risk. If surgery is needed, it is recommended to choose a regular hospital and a professional doctor to perform the operation, and the chance of risk will be greatly reduced.
