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

There are many factors that induce lung cancer in life, such as long-term smoking or passive smoking, exposure to strong radiation in the working environment, etc. These are very likely to induce lung cancer. The early symptoms of lung cancer are sometimes not very obvious, which leads to many people misdiagnosing the disease.

1. Cough

Coughing is the most obvious early symptom of lung cancer, but many people do not think it is a big deal. Only when they cough, have blood in their sputum or cough up blood, will they think that the condition is serious and needs treatment.

2. Low fever

Due to the influence of the disease, the patient's body is very likely to have low fever symptoms. The main cause of this symptom is that the tumor blocks the bronchus and causes obstructive pneumonia. However, due to the difference in degree, the patient will also show different symptoms.

3. Chest pain

In the early stages of lung cancer, mild chest pain will occur, mainly manifested as dull pain and dull pain. The location of the pain is not certain, and the relationship with breathing is not very certain. If the pain persists, it means that the cancer has affected the pleura.

4. Blood in sputum

We have mentioned in the cough symptoms that many people do not care about coughing, but when there is blood in the sputum or when coughing up blood, everyone will realize the severity of the condition. This symptom is mainly due to a small amount of bleeding caused by capillary damage, tumor inflammation and necrosis, and the blood is often mixed with the sputum, showing a certain intermittent state.

Among the early symptoms of lung cancer, many patients only seek medical attention because of the appearance of blood in sputum. However, at this time, the best time for treatment has often been missed. Therefore, it is best for us to diagnose and treat in time when the symptoms are mild.
