What are the early symptoms of lung cancer? 3 major symptoms that should not be ignored

What are the early symptoms of lung cancer? These three symptoms cannot be ignored. Why must we emphasize early screening of lung cancer, early detection and early treatment? It is estimated that many people do not take it too seriously, but if you know the difference in treatment between early-stage cancer patients and late-stage cancer patients, it is estimated that more people will pay more attention. For example, for non-small cell lung cancer, if the patient is discovered early, the median survival time after surgery may be 10 years, and the median survival time may be 1 to 4 years. However, if the terminal stage is detected, the median survival time may be 6 to 8 months. The early or late detection of the disease is directly related to the length of life, which shows the importance of early detection and treatment!

However, the current situation of early detection of lung cancer in my country is not good. Many lung cancer patients are already in the advanced stage when they discover their condition. There are very few patients in the middle stage, and there are very few who discover it early. The failure of lung cancer patients to be detected early is not entirely due to the patients' vigilance! If lung cancer is not detected early, it cannot be blamed on the patients for not being vigilant. Rather, in the early stages of lung cancer, it is difficult for patients to feel symptoms, or the symptoms are mild. In addition, the obviousness of the early symptoms of lung cancer is also closely related to the location of the tumor. About 30-40% are below the segmental bronchus and have almost no symptoms. In addition, if the patient does not have a targeted physical examination, it is difficult to detect in the early stages.

About 60% of central lung cancers have symptoms in the early stages. However, the condition is not serious in the early stages, and the symptoms are mild and non-specific, so they are easily ignored by patients. We should learn more about health knowledge and have a certain understanding of major high-risk diseases, especially for some high-risk groups.

What are the early symptoms of lung cancer?

1. Cough: This is also the most common early symptom of lung cancer. Patients often cough continuously, but with little or no sputum. In addition, conventional cough treatment drugs are ineffective. This cough is caused by tumor irritation of the bronchus.

2. Chest tightness: Often confused with heart conditions and ignored by patients. The tumor is in the trachea, and the tracheal wall is irritated and uncomfortable. As the disease becomes more serious, the tumor grows larger and the breathing becomes shorter.

3. Bloody sputum: Another name for bronchial lung cancer or lung cancer. Many lung cancer patients develop lesions in the bronchial mucosal wall. In the early stage of the disease, there are few tumors and the wound surface is also small. The blood vessels are thin, and the patient coughs with sputum and coughs up bloody sputum.

In addition to understanding the early symptoms, quitting smoking is the most important preventive measure that needs to be mentioned again. Tobacco is the primary risk factor for lung cancer, and quitting smoking is the most important and effective way to prevent lung cancer. In addition, kitchen fumes and decoration pollution should also be avoided as much as possible. When the air quality is poor, try to wear a fog mask when going out to reduce the invasion of various harmful factors of lung cancer.
