How to detect early lung cancer? Get checked immediately if you have these 4 symptoms

Lung cancer is a disease that everyone is familiar with. It can be said that "cancer is terrifying". Lung cancer is a very painful thing and endangers people's lives. In recent years, the incidence of lung cancer in China has been increasing, and the mortality rate has remained high. People don't know much about the early symptoms of lung cancer, and they also want to know what the precursors of lung cancer are. Now I will popularize it for everyone.

1. Coughing up blood. Nearly 80% of lung cancer patients will cough up blood after contracting lung cancer because lung cancer tumor cells invade the bronchial mucosa. Since the physical conditions of each lung cancer patient are different, the degree of coughing up blood is different. Some lung cancer patients will have blood in their sputum. As the disease continues to worsen, lung cancer tumor cells invade the blood vessels, causing the patient to vomit blood, directly endangering the life of the lung cancer patient.

2. Cough . The most common symptom of lung cancer patients is cough, which is related to the bronchial mucosa. Lung cancer cells are very sensitive to external stimuli due to their large inertia, which can cause cough. The most common manifestation of lung cancer is irritating and paroxysmal cough, and taking cough suppressants will not help.

3. Chest pain . Many lung cancer patients will have chest pain symptoms, the main manifestation of which is irregular pain in the chest. In most cases, lung cancer cells will invade the pleura or chest wall, causing pain. If chest pain is found, it may be related to lung cancer cells invading the nerves around the bronchus.

4. Blood in sputum . Blood in sputum is a common symptom in lung cancer patients, but blood in sputum has different causes and corresponding diseases, so some patients do not pay attention to this symptom. Coughing up blood in lung cancer is continuous and staged. From this, it can be distinguished that if there is a ruptured blood vessel, it will cause a large amount of vomiting blood, not blood in sputum.

The precursors of lung cancer are similar to the early symptoms, which can be manifested as weight loss, fever, anemia, and local manifestations such as chest pain, shortness of breath, chest tightness, cough, hoarseness, etc.

After the above introduction, I believe everyone has a general understanding of the four early symptoms and many precursors of lung cancer. Therefore, if you find yourself having the above-mentioned typical symptoms, please seek medical attention immediately without hesitation.
