What are the early extrapulmonary manifestations? The four early symptoms of lung cancer should not be ignored

Speaking of cancer, everyone's first reaction is fear and terror. It is true that the mortality rate of cancer has been rising year by year in recent years, but this does not mean that cancer is incurable. If cancer is discovered in the early stages and treated in time, there is still a high chance of recovery, and this is the case with lung cancer. Today, experts will introduce the early symptoms of lung cancer to everyone, so that everyone can have a deeper understanding of this disease.

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.
