What are the symptoms of advanced lung cancer? Introduction to the symptoms of advanced lung cancer

The existence and growth of lung cancer will inevitably have adverse effects on the patient's body. Lung cancer is more serious in the late stage and requires timely symptomatic treatment. 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.

Although no studies have shown that the occurrence of lung cancer is directly related to air pollution, clinical data show that there are more lung cancer patients in cities with serious air pollution levels. Moreover, once these patients develop into the late stage, many of them will have to accept the fact of death, so it is important to understand the relevant symptoms in advance.

So, what are the symptoms of advanced lung cancer?

The existence and growth of lung cancer will inevitably have adverse effects on the patient's body. In the late stage of lung cancer, the condition is more serious and requires timely symptomatic treatment. 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 in the chest have symptoms of chest pain.

In the late stage of lung cancer, patients are more likely to experience shortness of breath, and some also have pleural effusion. Almost all patients with advanced lung cancer that has spread regionally have shortness of breath to varying degrees. Normal tissue fluid produced by the lungs and myocardium flows back through the lymph nodes in the middle of the chest. If these lymph nodes are blocked by tumors, this tissue fluid will accumulate in the pericardium to form pericardial effusion or accumulate in the chest cavity to form pleural effusion.

Therefore, in the late stage of the disease, the symptoms of lung cancer are mainly hoarseness, shortness of breath, pleural effusion, edema, etc. Generally, as long as these symptoms appear, it means that the disease is more serious or has developed to the late stage of the disease. At this time, comprehensive treatment methods can be used to relieve the pain.
