What are the common symptoms of lung cancer? Common symptoms of early and late stage lung cancer

What are the common symptoms of lung cancer? 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.

What are the common symptoms of lung cancer? Lung cancer patients will also show different symptoms at different stages of the disease. There are no obvious special symptoms in the early stage of lung cancer, but early lung cancer can also be discovered through some specific manifestations. What are the common symptoms of early and late stage lung cancer? Let's take a look at the experts' introduction.

【Early symptoms of lung cancer】

Lung cancer does not have any special symptoms in the early stage. It only has the common symptoms of general respiratory diseases, such as cough, blood in sputum, low fever, chest pain, shortness of breath, etc., which are easy to be ignored. The specific manifestations of common symptoms of lung cancer in the early stage:

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

2. Low-grade fever. When a tumor blocks the bronchus, there is often an obstructive lung lobe. The degree of the disease varies. In mild cases, there is only a low-grade fever, while in severe cases, there is a high fever. The disease may temporarily improve after medication, but it will relapse soon.

3. Chest pain. In the early stages of lung cancer, chest pain is mild and is mainly manifested as dull pain, dull pain, and the location is uncertain, and the relationship with breathing is also uncertain. If the pain persists, it means that the cancer may have affected the pleura.

4. 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.

【Symptoms of advanced lung cancer】

1. 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 become swollen 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;

2. Hoarseness is the most common symptom. The recurrent laryngeal nerve that controls the left side of the vocal 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 vocal organ.

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 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 in the chest cavity to form pleural effusions. Both of the above situations 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.

In addition, since part of the lung tissue has lost its respiratory function due to the tumor, the overall respiratory function is impaired and respiratory discomfort occurs. This discomfort initially only occurs during exercise, but eventually it can be felt even when resting.

The above is what the experts introduced to you about the early and late symptoms of lung cancer. Knowing the early symptoms of lung cancer can help you detect the disease early and treat it early. Knowing the late symptoms of lung cancer can help you correctly understand the progression of the disease and treat it according to the symptoms.
