What are the symptoms of early lung cancer? Early symptoms of lung cancer and extrapulmonary manifestations

The incidence of lung cancer has been increasing in recent years, which is related to the improvement of people's living standards and people's lack of attention to dietary rules. However, the early symptoms of lung cancer are not very obvious, and are common to some common respiratory diseases, so they are often ignored. In order to help everyone better prevent and treat lung cancer, some specific early symptoms are introduced below.

Early symptoms of lung cancer

1. Cough

Lung cancer grows on bronchial lung tissue, which usually causes respiratory irritation and irritating cough.

2. Low fever

When the tumor blocks the bronchus, there is often obstructive lung lobe, with varying degrees of severity. In mild cases, there is only low fever, while in severe cases, there is high fever. There may be temporary improvement after medication, but it will soon relapse.

3. Chest pain

In the early stages of lung cancer, chest pain is mild, mainly manifested as dull pain, dull pain, and uncertain location, and the relationship with breathing is also uncertain. If the pain persists, it means that the cancer may have affected the pleura.

4. Blood in sputum

When tumor inflammation causes necrosis and capillary damage, there will be a small amount of bleeding, which is often mixed with sputum and appears intermittently or intermittently. Many lung cancer patients seek medical treatment because of blood in sputum.

Early extrapulmonary manifestations

1. Bone and joint symptoms

This type of symptom is more common. Lung cancer cells can produce certain special endocrine hormones (xenohormones), antigens and enzymes, which act on the bone and joint parts, causing bone and joint swelling and pain, often involving the tibia, fibula, ulna, radius and other bones and joints. The ends of the fingers and toes often swell and become clubbed, and X-ray examinations can show periosteal hyperplasia.

2. Shoulder and back pain

Peripheral lung cancer often develops posteriorly and upwards, eroding the pleura, involving the ribs and chest wall tissue, and causing shoulder and back pain. Such patients rarely have respiratory symptoms.

3. Hoarseness

Lung cancer metastasis compresses the laryngeal nerve, which can paralyze the vocal cords and cause hoarseness. Since lung cancer metastasis can appear in the early stage and sometimes grow faster than the primary lesion, the clinical manifestations of metastasis may appear before the primary lesion.

Lung cancer is not incurable, especially in the early stages, and patients should have the necessary confidence. Lung cancer patients must eat a reasonable diet in their daily lives and eat more anti-lung cancer foods. In addition, lung cancer patients can also cooperate with Chinese medicine treatment to improve their diet, improve their quality of life, and enhance their body's immune ability. I hope that lung cancer patients can recover as soon as possible.
