Symptoms and signs of primary lung cancer

summary

Lung cancer is the most common primary malignant tumor of lung. Most of lung cancer originated from bronchial mucosa epithelium, so it is also called bronchial lung cancer. Shanghai Zhongda Tumor Hospital experts said that lung cancer confined to the basement membrane is called cancer in situ, and can spread through lymphatic blood or bronchial metastasis. Lung cancer occurs in bronchial mucosa epithelium, also known as bronchial cancer. Let's talk about the symptoms and signs of primary lung cancer.

Symptoms and signs of primary lung cancer

Edema of face and neck. On the right side of the mediastinum is the superior vena cava, 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 be inflamed at first due to poor return flow, and finally lead to facial and neck edema, which needs timely diagnosis and treatment;

Hoarseness is the most common symptom. The recurrent laryngeal nerve (RLN), which controls the left vocal function, descends from the neck to the chest, bypasses the great blood vessels of the heart and goes up to the larynx, thus dominating the left side of the vocal organ.

Shortness of breath. Almost all lung cancer patients with regional spread have different degrees of shortness of breath. The normal tissue fluid produced by the lungs and myocardium is returned from the lymph nodes in the middle of the chest. If these lymph nodes are blocked by the tumor, the tissue fluid will accumulate in the pericardium to form pericardial effusion or in the chest to form pleural effusion. Both can cause shortness of breath.

matters needing attention

Advanced lung cancer patients are very painful, patients should continue to adhere to treatment, can reduce symptoms and prolong survival. Because many smokers have different degrees of chronic lung disease, it is difficult to identify shortness of breath. In addition, due to the loss of respiratory function due to the growth of tumor in some lung tissues, the respiratory function of the lung is impaired, resulting in respiratory discomfort. At first, this discomfort is only produced during exercise, and finally it can be felt even at rest.
