What are the symptoms of acute lung cancer

Nowadays, people are under great pressure in life and work, which has led to many people developing some bad living habits, thus causing the occurrence of diseases. Lung cancer is one of them. The current incidence of this disease is very high, so it is necessary for us to understand what symptoms of lung cancer are? The following is a relevant introduction.

The most common symptoms of early lung cancer are:

1. Cough, mostly irritating dry cough, no sputum or a small amount of white sticky sputum, especially for long-term heavy smokers over 40 years old, if there is no obvious cause of irritating dry cough lasting 2-3 weeks, treatment is ineffective, or there are chronic respiratory diseases, the nature of the cough has changed, so be vigilant;

2. Hemoptysis, usually bloody sputum or sputum with blood;

3. Lung cancer often causes mild chest tightness in the early stages. If it involves the parietal pleura or directly invades the chest wall, it can cause persistent pain in that area. It should be emphasized that there are no specific symptoms in the early stages of lung cancer. Any respiratory symptoms that are not cured for more than 2 weeks or worsening of the original symptoms should alert you to the possibility of lung cancer.

Typical symptoms of lung cancer

1. Cough, mostly irritating dry cough, no sputum or a small amount of white sticky sputum;

2. Hemoptysis, usually bloody sputum or sputum with blood;

3. Chest pain. If lung cancer involves the parietal pleura or directly invades the chest wall, it can cause persistent pain in that area.

4. Fever. Fever in lung cancer is usually persistent low-grade fever, which lasts for a long time and recurs repeatedly.

5. Chest tightness

Symptoms of advanced lung cancer

1. Chest pain. Most patients with lung cancer that has regional intrathoracic metastasis have symptoms of chest pain.

2. Difficulty breathing and shortness of breath. Difficulty breathing occurs when the tumor compresses the large airways or produces a large amount of pleural effusion;

3. Edema of the face and neck. If the tumor invades the right side of the mediastinum and compresses the superior vena cava, the return of the superior vena cava will be blocked, causing congestion and varicose veins in the face, neck, and upper limbs.

4. Hoarseness. The tumor directly invades the recurrent laryngeal nerve or metastasizes to the mediastinal lymph nodes, thereby compressing the recurrent laryngeal nerve, which can cause hoarseness.

5. Weight loss and emaciation are one of the most common symptoms of advanced malignant tumors. In advanced patients, due to tumor toxins and consumption, combined with infection, pain, etc., the loss of appetite may cause emaciation or cachexia.

6. Symptoms caused by distant metastasis of lung cancer, such as bone metastasis pain, headache, dizziness, weakness on one side of the limbs caused by brain metastasis, etc.

Because when lung cancer occurs, patients not only suffer from physical pain but also great psychological pressure, so in daily life it is necessary for us to learn more about lung cancer. If we find anything abnormal in our body, we should go to the hospital for examination and treatment in time. Early treatment can effectively control the development of the disease.
