What are the early symptoms of lung cancer?

1. Hoarseness

Hoarseness is one of the most important early manifestations of lung cancer. This symptom usually occurs in pharyngitis, colds and acute bronchitis; after thyroid surgery, pharyngeal surgery, it can also occur due to improper voice and excessive talking, or even after smoking and drinking a lot. However, most of these hoarseness symptoms can be treated symptomatically or healed by rest. However, the hoarseness caused by lung cancer, thyroid cancer and laryngeal cancer is different from the above hoarseness, and it is not easy to recover, which is more prominent in lung cancer.

2. Cough

It is the earliest and most common sign of lung cancer. Because the onset is often similar to a cold or bronchitis, it is easy to be ignored. Therefore, people who have never had chronic respiratory diseases should be alert to the possibility of lung cancer if they continue to cough for more than 3 weeks without active treatment.

3. Hemoptysis

It is the third most common sign of lung cancer. It is often caused by cancer cells invading the bronchial mucosa. The amount of hemoptysis is usually small, often with bloody sputum, which can last for weeks or months or occur intermittently. Because the amount of hemoptysis is small or occurs intermittently, it is easy to be ignored. In fact, about 1/4 of middle-aged and older people with bloody sputum are caused by lung cancer.

4. Fever

Fever is the fourth most common sign of lung cancer. When central lung cancer grows in the bronchus and develops to the point where the lumen is semi-obstructed or completely obstructed, obstructive pneumonia may occur. The fever is usually at 38°C and can be easily reduced through anti-inflammatory treatment. However, if the obstructive lesions are not removed, pneumonia will reappear soon, resulting in repeated pneumonia.

5. Chest pain

It is the fifth most common sign of lung cancer. It accounts for more than half of lung cancer patients, especially peripheral lung cancer, and chest pain can be the first symptom. This is because cancer cells infiltrate the pleura. Chest pain is often fixed in the lesion site, and in the early stage, it is mostly intermittent pain and discomfort. It can be aggravated by changing body position, deep breathing and coughing. Therefore, if chest pain occurs in a fixed location due to unknown reasons, corresponding examination should be carried out early.
