The symptoms of lung cancer in the late stage will manifest in many aspects

The symptoms of lung cancer are a topic that people are more concerned about. Generally, if the symptoms of early lung cancer are not discovered, then what awaits the patient will be the symptoms of late-stage lung cancer. Do you know what the symptoms of lung cancer are? Let the experts introduce us to the symptoms of lung cancer .

Symptoms of locally advanced lung cancer: The chest cavity is a very complex space. Three-quarters of the lung surface is surrounded by the chest wall, which is composed of a thin layer of lining (parietal pleura), fat, muscle, ribs and skin in different proportions. Tumor invasion of any of the above parts will cause pain. Therefore, most patients with lung cancer that have regionally spread to the chest have symptoms of chest pain.

What are the main symptoms of lung cancer?

1. Hoarseness is a symptom of advanced lung cancer. The recurrent laryngeal nerve that controls the left side of the voice function goes down from the neck to the chest, bypasses the large blood vessels of the heart and goes back up to the larynx, thus controlling the left side of the voice organ. Therefore, if the tumor invades the left side of the mediastinum and compresses the recurrent laryngeal nerve, hoarseness will occur, but there will be no sore throat or other symptoms of upper respiratory tract infection.

2. Shortness of breath and pleural effusion. Symptoms of regionally spread lung cancer are almost always accompanied by shortness of breath to varying degrees. Normal tissue fluid produced by the lungs and myocardium is returned by the lymph nodes in the middle of the chest. If these lymph nodes are blocked by tumors, these tissue fluids will accumulate in the pericardium to form pericardial effusion or in the chest cavity to form pleural effusion. Both of the above situations can lead to shortness of breath, which is also a symptom of lung cancer.

3. Edema of the face and neck. There is a superior vena cava on the right side of the mediastinum, which transports venous blood from the upper limbs and head and neck back to the heart. If the tumor invades the right side of the mediastinum and compresses the superior vena cava, the jugular vein will initially become swollen due to poor blood return, and eventually the symptoms of lung cancer will also lead to edema of the face and neck, which needs to be diagnosed and treated in time.

4. What are the other symptoms of lung cancer? Lung cancer patients may experience unexplained headaches, vomiting, visual impairment, and personality and temper changes, which may be caused by intracranial hypertension or cranial nerve damage caused by lung cancer metastasis to the brain. This is common in small cell lung cancer and adenocarcinoma types.

5. In addition to the above-mentioned common metastatic sites, lung cancer also has less common metastatic sites such as skin, subcutaneous tissue, muscle, abdominal cavity, heart, etc. Symptoms are often related to the metastatic site. For example, if it metastasizes to the heart, symptoms such as chest tightness, palpitations, and even shortness of breath, syncope, and heart rhythm disorders may occur.

The above is an introduction to the symptoms of lung cancer. Do you understand them? I hope that if patients find that they have the disease, timely treatment is the most important thing. Of course, they must face the disease squarely and receive treatment seriously to ensure their health.
