What are the symptoms of lung cancer? Six typical symptoms of lung cancer

Hoarseness is the most common symptom. The recurrent laryngeal nerve that controls the left side of the vocal function descends from the neck to the chest, bypasses the large blood vessels of the heart and returns upward to the larynx, thereby controlling the left side of the vocal organ.

Lung cancer has a high prevalence in life, so everyone has a certain understanding of lung cancer. Lung cancer is a disease that is difficult to treat. For a disease like lung cancer, we must strive to achieve early detection and early treatment. Therefore, we must have a certain understanding of the symptoms of lung cancer.

Symptoms of liver cancer

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

2. When a low-fever tumor blocks the bronchus, obstructive pneumonia often occurs with varying degrees. Mild cases have only low fever, while severe cases have high fever. The condition may temporarily improve after taking medication, but will soon relapse.

3. Chest pain In the early stage of lung cancer, chest pain is mild, mainly manifested as dull pain, dull pain, and the location is not certain, and the relationship with breathing is also uncertain. If the pain persists, it means that the cancer may involve 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.

5. Facial and neck edema. On the right side of the mediastinum is the superior vena cava, which transports venous blood from the upper limbs and head and neck back to the heart. If the tumor invades the right side of the mediastinum and compresses the superior vena cava, it will initially cause the jugular vein to become swollen due to poor blood return, and eventually lead to facial and neck edema, which requires timely diagnosis and treatment.

6. Hoarseness. The recurrent laryngeal nerve that controls the left side of the vocal function goes down from the neck to the chest, bypasses the large blood vessels of the heart and goes back up to the larynx, thus controlling the left side of the vocal organ.
