We cannot ignore the dangers of early lung cancer

I believe everyone knows that smoking is harmful to health, and the biggest harm is to the human lungs. In severe cases, it can also cause lung cancer. The lungs are in the body, and patients often don't know when they are sick, and think it is a minor problem. So, what are the harms of lung cancer to the human body? Experts give the following introduction.

1. Cancer can cause bronchial obstruction, the normal alveolar sac cavity disappears, affecting the exchange of oxygen and carbon dioxide, and the patient will feel chest tightness and shortness of breath.

2. If lung cancer occupies most of the lungs, it will have a huge impact on the patient's breathing.

3. The nerves in the bronchus are quite sensitive. Cancer can stimulate the bronchus, causing the patient to cough. Everyone has this experience in life: a grain of rice falls into the bronchus, and after a few coughs, the grain is coughed out and the patient stops coughing. However, the cancerous mass growing in the bronchus cannot be coughed out, so there will be bursts of violent dry coughs that are not easy to stop. Sometimes there is even the phenomenon of coughing up blood, which is the most typical hazard of lung cancer.

4. Because cancer blocks the bronchi, the bronchial secretions, namely sputum, cannot be eliminated, causing bacteria to grow and cause pneumonia and fever. This type of pneumonia is called obstructive pneumonia.

5. If the condition is severe enough, it may cause chest pain and pleural effusion. Excessive pleural effusion compresses the lungs, making it more difficult for the patient to breathe, which is quite difficult to treat.

6. Experts point out that if lung cancer is not controlled in time and rapidly deteriorates, it will pose a great threat to the patient's life.
