What are the early symptoms of lung cancer? Introduction to several symptoms of early lung cancer

Lung cancer is a relatively common type of cancer, and the causes of lung cancer include many aspects. When you have lung cancer, the early symptoms are not obvious, and some common symptoms will appear, such as coughing or chest pain. The following is a detailed introduction to the early symptoms of lung cancer.

Let's talk about cough first. It 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 the cough persists for more than 3 weeks after active treatment, and further examination is necessary. As for elderly patients with chronic bronchitis, the incidence of lung cancer is higher than that of ordinary people, but their early cough symptoms are often easily confused with the original chronic cough, and diagnosis is often delayed. At this time, it is necessary to pay attention to 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 and choking coughs and severe coughs with little sputum, which is inconsistent with the original four-season disease pattern. Active anti-infection treatment is ineffective, and the symptoms are aggravated.

Hemoptysis is the second most common symptom of lung cancer, which 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 bloody sputum appears for unknown reasons, do not be careless.

Chest pain is also a common symptom of lung cancer. Especially for peripheral lung cancer, chest pain may be the first symptom. It is caused by 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. Coughing can make it worse. Therefore, if chest pain occurs in a fixed location for unknown reasons, corresponding examinations should be carried out early.

The above content introduces the early symptoms of lung cancer in detail. After reading the above introduction, everyone should have a clear understanding of the symptoms of lung cancer. If you find that you have symptoms of lung cancer, don't be too nervous or afraid. You should go to the hospital for diagnosis first, because some diseases have similar symptoms to lung cancer.
