What are the symptoms of early lung cancer? Beware of several early symptoms of lung cancer

Everyone is very familiar with lung cancer. It is the most common malignant tumor in the respiratory system. Clinically, the incidence of lung cancer is relatively high and the affected population is relatively wide. Therefore, everyone should do a good job in preventing lung cancer and pay more attention to changes in the body. Once the body has long-term chest pain accompanied by cough, hemoptysis and other symptoms, it should be taken seriously, as this may be an early symptom of lung cancer.

[Long-term chest pain should alert you to early symptoms of lung cancer]

1. Hemoptysis: Cancerous tissue invading the bronchial mucosa can cause hemoptysis in patients. The amount of hemoptysis is often blood-streaked sputum and can last for weeks or months or occur intermittently. The amount is generally small, so it is easy to be neglected.

Countermeasures: When unexplained sputum and blood appear, do not be careless and go to the hospital immediately for relevant examinations.

2. Cough: Cough is the earliest and most common symptom of lung cancer patients. It is often similar to a cold or bronchitis at the onset, often with irritating and severe coughs, little sputum, and often with metallic sounds. It is inconsistent with the original four-season disease pattern and is therefore easily ignored.

Countermeasures: Anyone who has no chronic respiratory diseases in the past, especially those over 40 years old, who has a persistent cough for more than 3 weeks after active treatment should be alert to the possibility of lung cancer and undergo further examination.

3. Chest pain: It is caused by cancer tissue infiltrating the pleura. Chest pain is often fixed at the site of the lesion and is often intermittent and uncomfortable in the early stages. It can be aggravated by changes in body position, deep breathing, and coughing.

Countermeasures: If chest pain occurs in a fixed location without apparent cause, appropriate examinations should be carried out as soon as possible.

Long-term chest pain should alert you to the early symptoms of lung cancer. The above is a detailed introduction. Oncologists say that when the above symptoms appear in the body, you should go to the hospital for examination in time to find out the cause and actively treat it, which can reduce the harm to the body.
