What are the symptoms of lung cancer

Lung cancer is the most common primary lung malignancy. Most lung cancers originate from the bronchial mucosal epithelium, so it is also called bronchial lung cancer. Every lung cancer patient suffers from both physical and psychological pain caused by lung cancer. So what are the symptoms of lung cancer? Here are some of the symptoms of lung cancer.

The following are early symptoms of lung cancer:

1. When a low-fever tumor blocks the bronchus, there is often an obstructive lung lobe with varying degrees of severity. In mild cases, there is only a low fever, while in severe cases, there is a high fever. The condition may temporarily improve after taking medication, but it will soon relapse.

2. Cough. Lung cancer grows on bronchial lung tissue, which usually causes respiratory irritation and irritating cough.

3. Blood in sputum. When tumor inflammation causes necrosis and capillary damage, there will be a small amount of bleeding, which is often mixed with sputum and appears intermittently or intermittently. Many lung cancer patients seek medical treatment because of blood in sputum.

4. Chest pain. In the early stage of lung cancer, chest pain is mild, mainly manifested as dull pain, dull pain, and the location is not certain, and the relationship with breathing is also uncertain. If the pain persists, it means that the cancer may involve the pleura.

The following are symptoms of advanced lung cancer:

1. Hoarseness is the most common symptom. 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.

2. Edema of the 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, it will initially cause the jugular vein to swell due to poor blood return, and eventually lead to edema of the face and neck, which needs to be diagnosed and treated in a timely manner;

3. Shortness of breath Almost all patients with regionally spread lung cancer experience shortness of breath to varying degrees. Normal tissue fluid produced by the lungs and myocardium is returned by the lymph nodes in the center of the chest. If these lymph nodes are blocked by tumors, these tissue fluids will accumulate in the pericardium to form pericardial effusions or in the chest cavity to form pleural effusions. Both of the above situations can cause shortness of breath. However, since many smoking patients have varying degrees of chronic lung disease, this brings certain difficulties to the identification of shortness of breath. In addition, since part of the lung tissue loses its respiratory function due to the growth of tumors, the overall respiratory function is impaired and respiratory discomfort occurs. This discomfort initially only occurs during exercise, but eventually it can be felt even at rest.
