What are the symptoms of advanced lung cancer?

When you are sick, you will have corresponding symptoms. The symptoms of each disease will change according to the stage of the disease. Lung tumor is one of the most common malignant tumors nowadays. So what are the symptoms of advanced lung tumor?

Specifically, the symptoms of advanced lung cancer are as follows:

Facial and neck edema: 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, it will initially cause the jugular vein to swell due to poor blood return, and eventually lead to facial and neck edema, which needs to be diagnosed and treated in a timely manner;

Hoarseness is the most common symptom of advanced lung cancer: the recurrent laryngeal nerve that controls the left side of the voice function descends from the neck to the chest, bypasses the large blood vessels of the heart and returns upward to the larynx, thereby controlling the left side of the voice organ.

Shortness of breath: Almost all patients with regionally spread lung tumors experience varying degrees of shortness of breath. Normal tissue fluid produced by the lungs and myocardium flows back to 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 effusions or accumulate in the chest cavity to form pleural effusions. Both of these situations can cause shortness of breath.

However, since many smokers have varying degrees of chronic lung disease, it is difficult to identify shortness of breath. In addition, since part of the lung tissue loses its respiratory function due to tumors, the entire respiratory function is impaired, resulting in respiratory discomfort. This discomfort initially only occurs during exercise, but eventually can also be felt during rest.
