Be careful with persistent hiccups. Some of them are caused by advanced lung cancer. Most of them can only be treated conservatively

Lung cancer is a malignant lung disease caused by malignant transformation of normal cells. Early stage lung cancer can be cured by surgery. Even if middle and late stage lung cancer can be operated, the cure rate is much lower. Early lung cancer usually has no obvious symptoms, once symptoms appear, it is often late. The symptoms of lung cancer include the local symptoms caused by lung cancer tumor, the symptoms caused by lymph node metastasis, and the symptoms caused by distant metastasis. You can understand the first and third items, but many people can’t understand the symptoms caused by lung cancer metastasis to lymph nodes. Here are two easily ignored external symptoms caused by lymph node enlargement . < / P > < p > hoarseness you must first think of laryngitis or glottis, an important vocal structure of the human body. This is consistent with the probability of disease phonation. Hoarseness is indeed related to these two problems. In particular, acute laryngitis caused by virus and bacteria is the most common cause of hoarseness in the human body. However, in individual cases, lymph node metastasis of lung cancer oppresses the longitudinal lung between the two lungs Phrenic recurrent laryngeal nerve (RLN) can lead to persistent hoarseness, which is one of the important symptoms of lung cancer metastasis. < / P > < p > burping is a common phenomenon in daily life. Most of burping is caused by stimulation of phrenic nerve. Phrenic nerve comes from a branch of cervical plexus. It is a mixed nerve, which can not only sense but also control muscle movement. Its motor fibers control the diaphragm, and the sensory fibers are distributed in the skin outside the lung and heart – pleura and pericardium; it is generally believed that the right diaphragm The sensory fibers of nerves can also be distributed to the liver, gallbladder and biliary system. The main manifestation of phrenic nerve injury is ipsilateral diaphragm paralysis. Hiccup may occur when phrenic nerve is stimulated. Inflammation of the gallbladder can stimulate the right phrenic nerve endings. At this time, the patient may feel pain in the right shoulder, so it may be misdiagnosed as a lesion in the shoulder joint or supraclavicular region, and ignore the inflammation of the gallbladder. < / P > < p > the phrenic nerve runs in the mediastinum between the two lungs. There are large blood vessels in the mediastinum, outside the esophagus and trachea, and lymph nodes. These lymph nodes are usually very small and do not cause trouble. If they become enlarged due to inflammation or tumor metastasis, they may oppress the surrounding organs and cause symptoms, especially when the lung cancer metastases to the lymph nodes, which may lead to serious enlargement of lymph nodes Continuous compression or stimulation of the phrenic nerve will lead to rhythmic contraction of the diaphragm, resulting in belching. < / P > < p > therefore, if the mass is detected in the lung, if there is continuous burping, it is basically in the middle stage, at least if the ipsilateral lymph node has metastasized. This kind of situation can be operated, but most of it can not be cured. If the lymph node and tumor are not on one side, it will lose the opportunity of operation, and can only be treated with chemotherapy, radiotherapy, immunotherapy and targeted therapy. < / P > < p > therefore, if you have inexplicable hoarseness and continuous burping for a long time, you should be careful. If you have symptoms of cough and expectoration at the same time, you should be more careful. It is necessary to have a CT examination in the hospital. If you find a mass, the probability is lung cancer, you should do bronchoscopy, lung puncture and other examinations to further confirm the diagnosis. HEALTHY LIFE
