Lung cancer chest tightness and hemoptysis

Lung cancer has become a disease with an increasingly high incidence rate because more and more people now choose to smoke. Smoking has a great impact on the lungs, and if you are not careful over time, it can easily turn into lung cancer. Because the lungs are related to human breathing, some people with lung cancer will experience chest tightness. However, some lung cancer patients will not only experience chest tightness, but also cough up a lot of blood from their bodies. What is going on?

1. Why does lung cancer cause coughing up blood?

Lung cancer patients, due to the influence of the tumor, have blocked the passage of gas, which stimulates the bronchial wall and makes the trachea want to expel foreign objects, thus causing coughing. Sometimes the sputum coughed up contains blood, which is what we call hemoptysis. In addition, some Chinese medicine practitioners believe that the reason for coughing up blood in lung cancer is that the lung network is damaged, causing blood to be coughed out from the lungs through the airway, or it may be pure bright red blood, or a mixture of sputum and blood, or there may be blood in the sputum.

2. What is hemoptysis?

1. Respiratory system diseases: such as tuberculosis, bronchitis, pneumonia, lung tumors, bronchial stones, etc.

2. Circulatory system diseases: such as aortic aneurysm, pulmonary infarction, hypertensive heart disease, etc.

3. Systemic hemorrhagic diseases: such as hemophilia, aplastic anemia, epidemic hemorrhagic fever, uremia, leukemia, etc.

4. Trauma: Chest trauma can sometimes cause hemoptysis.

3. What kind of hemoptysis is lung cancer?

For hemoptysis caused by lung cancer, whether it is primary lung cancer or secondary lung cancer, severe hemoptysis generally does not occur. Most cases are persistent or intermittent blood in sputum or small amounts of hemoptysis, which are caused by tumor blood vessel rupture and other reasons.

4. Clinical manifestations of lung cancer

1. Cough is the first symptom of lung cancer. It is a paroxysmal irritating cough characterized by dry cough or white foamy sputum, and a small amount of bloody sputum may appear in combination with hemoptysis.

2. Fever can be inflammatory fever or cancer fever. Inflammatory fever is caused by obstructive pneumonia caused by tumors, and cancer fever is caused by necrosis of tumor tissue and absorption of toxins by the body. Inflammatory fever can be recovered after treatment, but it is easy to relapse. However, anti-inflammatory treatment is ineffective for treating cancer fever.

3. Chest tightness, chest pain, or shoulder and back pain. When the tumor compresses the trachea, chest tightness and shortness of breath will occur. When it involves the pleura or chest wall, there will be a dull pain in the chest, sometimes severe pain, which can radiate to the shoulders and back.

4. Others: including unexplained fatigue, weight loss, hoarseness, etc.
