What are the typical early symptoms of lung cancer? Three typical early symptoms of lung cancer

The early typical symptoms of lung cancer are what we must know in the process of treating lung cancer. In fact, many lung cancer treatments are not very effective because they are not carried out in the early stages. Here are some of the early typical symptoms of lung cancer.

1. Cough is the earliest and most common symptom of lung cancer patients. Because the onset is often similar to a cold or bronchitis, it is easy to be ignored. Therefore, people who have no chronic respiratory diseases in the past, especially those over 40 years old, should be alert to the possibility of lung cancer if their cough persists for more than three weeks after active treatment, and further examination is required.

As for elderly patients with chronic bronchitis, the incidence of lung cancer is higher than that of the general population, but their early cough symptoms are often easily confused with the original chronic cough, and the diagnosis is often delayed. At this time, it is necessary to pay attention to the changes in the nature and regularity of cough. Due to the stimulation of cancer tissue on the bronchial mucosa, lung cancer patients often have irritating coughs and severe coughs with little sputum, which is inconsistent with the original seasonal pattern of disease onset. Active anti-infection treatment is ineffective, and the symptoms are aggravated.

2. Hemoptysis is the second most common symptom of lung cancer. It is often caused by cancer tissue 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. Since the amount of hemoptysis is small or occurs intermittently, it is easy to be neglected. In fact, about 1/4 of those who have bloody sputum in middle-aged and older people are caused by lung cancer. Therefore, when unexplained sputum and blood appear, do not be careless.

3. Chest pain accounts for more than half of lung cancer patients, especially peripheral lung cancer, where chest pain can be the first symptom. This is due to the infiltration of the pleura by cancerous tissue. Chest pain is often fixed at the site of the lesion, and in the early stage, it is often intermittent pain and discomfort. It can be aggravated by changes in body position, deep breathing and coughing. Therefore, if chest pain occurs at a fixed site for unknown reasons, appropriate examinations should be conducted early.

These are what we need to know when treating lung cancer. Some people do not understand the key to treatment, so the treatment often fails to achieve the desired effect. I hope that when everyone undergoes the corresponding treatment, they can achieve relatively good treatment results.
