What symptoms does lung cancer cause? 8 common clinical manifestations of lung cancer

The early symptoms of lung cancer are easily ignored by patients because they are not very special and other diseases may also have these symptoms, such as low fever and cough. Therefore, many people do not know that they have lung cancer. So, what symptoms does lung cancer cause?

1. Irritating cough: Because lung cancer grows on bronchial lung tissue, patients often have irritating coughs due to respiratory irritation symptoms.

2. Blood in sputum: Tumor inflammation can cause necrosis and damage to capillaries accompanied by a small amount of bleeding, which is often mixed with sputum and appears intermittently or discontinuously. Once blood in sputum appears, you should seek medical attention immediately and receive a comprehensive examination.

3. Low fever: Because the tumor blocks the bronchus and causes obstructive lung lobe, mild cases only have low fever, while severe cases will have high fever. Even if the condition temporarily improves after taking medication, it will soon relapse.

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

5. Bone and joint symptoms: This type of symptom is more common. It often affects the tibia, fibula and other bones and joints, and the ends of the fingers and toes. Because lung cancer cells can produce certain special endocrine hormones, antigens and enzymes, these substances act on the bone and joint parts, causing swelling and pain in the bone and joints.

7. Shoulder and back pain: Peripheral lung cancer lesions often develop upward and backward, eroding the pleura, involving the ribs and chest wall tissue, thus causing shoulder and back pain.

8. Hoarseness: Metastatic lesions of lung cancer may appear in the early stage. The metastatic lesions may compress the laryngeal nerves and cause paralysis of the vocal cords, leading to hoarseness.
