What are the symptoms of middle and late stage lung cancer? Symptoms of middle and late stage lung cancer

Lung cancer patients in the late stage are in great pain, because at this time the cancer has often metastasized. Lung cancer patients are relatively common now, but once lung cancer is diagnosed, it is often in the middle and late stages. Some patients may not have obvious symptoms when they are first diagnosed, but as the disease progresses, the discomfort of the body will gradually increase. So, what are the symptoms of lung cancer in the middle and late stages?

Hoarseness is the most common symptom of patients with advanced lung cancer. The recurrent laryngeal nerve that controls the left side of the vocal 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 vocal 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.

Chest pain---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.

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.

Shortness of breath, 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 is returned by 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. Both of the above situations can cause shortness of breath.

Therefore, many patients with advanced lung cancer will experience facial edema, so everyone should pay attention to it. I believe that through this article, everyone has a better understanding of the disease of lung cancer. I hope that in the future, everyone can do a good job in preventing lung cancer.
