What are the dangers of lung cancer

I believe everyone knows that smoking is harmful to health. The biggest harm is to the human lungs. In severe cases, it can 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?

1. Cancer can cause bronchial obstruction, causing the normal alveolar sac cavity to disappear, affecting the exchange of oxygen and carbon dioxide, and causing the patient to 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 disease 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, and is very 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.

I believe that after reading the above introduction, many patients will be able to better understand the harm of lung cancer to the body. The editor believes that many diseases are caused by the patients' own carelessness. If there are any problems, please go to the hospital for consultation and treatment in time. In serious cases, take timely measures to restore your health as soon as possible.
