What are the clinical symptoms of lung cancer? 4 clinical symptoms of lung cancer

Lung cancer is a common tumor and a malignant tumor. With the improvement of the degree of industrialization of society, the incidence of lung cancer is getting higher and higher. The treatment of lung cancer is quite difficult and the mortality rate is extremely high. Male patients account for a large proportion of lung cancer patients. So what are the symptoms of this disease? Let me introduce them to you.

What are the clinical symptoms of lung cancer?

1. Facial and neck edema is a common symptom of advanced lung cancer. 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 advanced lung cancer will also lead to facial and neck edema, which needs to be diagnosed and treated in time.

2. Hoarseness is also one of the symptoms 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.

3. Shortness of breath and pleural effusion are also symptoms of advanced lung cancer. Ultimately, almost all patients with regionally spread lung cancer 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, these tissue fluids will accumulate in the pericardium to form pericardial effusions or accumulate in the chest cavity to form pleural effusions. Both of the above symptoms of advanced lung cancer can cause shortness of breath. However, because many smoking patients have varying degrees of chronic lung disease, this brings certain difficulties to the identification of shortness of breath.

4. Symptoms of advanced lung cancer include lung cancer pain. Pain is a common symptom of advanced lung cancer.
