What are the early symptoms of lung cancer? 9 early symptoms of lung cancer

The number of patients suffering from lung cancer is increasing, but they often lack relevant knowledge about lung cancer. By the time they discover the disease, it is already irreversible. In order to make everyone better understand lung cancer and detect the disease early, the following introduces the early symptoms of lung cancer.

1. Cough. About 2/3 of patients have this symptom, which can be mild dry cough or severe cough. Patients with chronic cough may experience changes in the nature of cough, such as frequent cough or irritating dry cough. It is often difficult for patients to pay attention to it, but it may be a precursor to lung cancer.

2. Chest pain. In the early stage, chest pain is mild, manifested as intermittent, mild dull pain or piercing pain, with uncertain location and relationship with breathing. If the tumor invades the pleura, the pain will be more severe, continuous and fixed;

3. Fever, fever of unknown cause, poor effect of antibiotic treatment;

4. Hemoptysis: Long-term smokers suddenly have blood in their sputum, blood streaks or small blood clots;

5. Difficulty breathing and progressive aggravation;

6. A small number of patients experience hoarseness;

7. Hypertrophy of the finger and toe joints, protrusions and bending of nails, often accompanied by pain;

8. Unexplained chest tightness and shortness of breath;

9. Gynecomastia refers to the enlargement of one or both sides of a man's breasts to become like those of a woman. When the above symptoms occur, especially for those who are over 40 years old and have been smoking for a long time, they should consider the possibility of lung cancer and go to the hospital for a comprehensive examination in time.

I hope that the early symptoms of lung cancer introduced above can help everyone. As long as we can clearly recognize the early symptoms of lung cancer and the harm caused by lung cancer, we can find and treat it in time. I hope everyone will not lose sight of the big picture and miss the best treatment period.
