What are the 3 major early symptoms of lung cancer? Early detection and early treatment

What are the three early symptoms of lung cancer? Early detection and early treatment. Why must we emphasize early screening, early detection and early treatment of lung cancer? I guess many people don't take it too seriously, but if you know the difference in treatment between early-stage cancer patients and late-stage cancer patients, I guess more people will pay more attention. And conventional cough treatment drugs have no effect on it. This type of cough is caused by tumor irritation of the bronchus.

What are the early symptoms of lung cancer?

1. Cough: This is also the most common early symptom of lung cancer. Patients often cough, but there is no sputum or little sputum. In addition, conventional drugs for treating cough are ineffective. This cough is caused by tumor irritation of the bronchus.
2. Chest tightness: It is often confused with heart conditions and therefore ignored by patients. Because there is a tumor in the trachea, the tracheal wall will be irritated and cause discomfort. When the condition worsens, the tumor will grow larger and the chest tightness and shortness of breath will worsen.
3. Bloody sputum: Bronchial lung cancer is another name for lung cancer. Most lung cancer patients develop lung cancer from the bronchial mucosal wall. In the early stages of the disease, there are fewer tumors and the wound surface is relatively small. The blood vessels are tiny, and patients will cough up blood with sputum, or even cough up bloody sputum.
In addition to understanding the early symptoms, quitting smoking is the most important means of prevention. Tobacco is the main risk factor for lung cancer, and quitting smoking is the most critical and effective way to prevent lung cancer. In addition, kitchen fumes and decoration pollution should be avoided as much as possible. When the air quality is poor, try to wear a smoke mask when going out to reduce the damage of various harmful factors of lung cancer.
