What are the early symptoms of lung cancer? Four common symptoms of early lung cancer

When tumor inflammation causes necrosis and capillary damage, there will be a small amount of bleeding, which is often mixed with sputum and appears intermittently or intermittently. Many lung cancer patients seek medical treatment because of blood in sputum.

When people have coughs and chest pain in their daily lives, they must seek timely treatment. Lung cancer is the most common primary lung malignancy. Most lung cancers originate from the bronchial mucosal epithelium, so it is also called bronchial lung cancer. In the past 50 years, the incidence and mortality of lung cancer have risen rapidly in countries around the world, especially in industrially developed countries. Lung cancer ranks first among male patients who die from cancer. According to preliminary statistics, about 1.2 million people are diagnosed with lung cancer each year worldwide, and the number of deaths from lung cancer each year exceeds the total number of deaths from breast cancer, colorectal cancer, and prostate cancer. In China, one person dies from lung cancer every 30 seconds.

Early symptoms of lung cancer:

Lung cancer does not have any special symptoms in the early stage. It only has the common symptoms of general respiratory diseases, such as cough, blood in sputum, low fever, chest pain, shortness of breath, etc., which are easy to be ignored. The common symptoms of lung cancer in the early stage are as follows:

1. Cough. Lung cancer grows on bronchial lung tissue, which usually causes respiratory irritation and irritating cough.

2. Low fever. When a tumor blocks the bronchus, there is often an obstructive lung lobe. The degree of the disease varies. In mild cases, there is only a low fever, while in severe cases, there is a high fever. The disease may temporarily improve after taking medication, but it will relapse soon.

3. Chest pain. In the early stages of lung cancer, chest pain is mild and is mainly manifested as dull pain, dull pain, and the location is uncertain, and the relationship with breathing is also uncertain. If the pain persists, it means that the cancer may have affected the pleura.

4. Blood in sputum. When tumor inflammation causes necrosis and capillary damage, there will be a small amount of bleeding, which is often mixed with sputum and appears intermittently or intermittently. Many lung cancer patients seek medical treatment because of blood in sputum.

There are many reasons for the occurrence of lung cancer, and there are many early symptoms. At the same time, experts say that the journey of fighting cancer is difficult, and it requires perseverance and waiting. The last 10% of the journey may account for 50% of the total effort.
