What are the early symptoms of lung cancer? Beware of the six symptoms of lung cancer

In our lives, lung cancer is a disease with a relatively high incidence rate, but many people do not know much about this disease. So what are the early symptoms of lung cancer? In order to better prevent this disease, everyone should understand the symptoms of lung cancer. Here are some early symptoms of lung cancer:

Early symptoms of lung cancer 1. Cough - Cough is a typical manifestation of lung cancer, and its early stage is very similar to a cold. Lung cancer grows on bronchial lung tissue, which usually causes respiratory irritation symptoms and irritating cough.

Early symptoms of lung cancer 2. Blood in sputum - coughing is often accompanied by varying degrees of sputum. In some cases, blood in the sputum is present. When tumor inflammation causes necrosis or 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 symptoms of lung cancer 3. Fever - Long-term persistent low-grade fever is one of the early symptoms of lung cancer. When the tumor blocks the bronchus, there is often obstructive pneumonia, with varying degrees, from low-grade fever in mild cases to high fever in severe cases. It may temporarily improve after medication, but will relapse soon.

Early symptoms of lung cancer 4. Chest pain - Chest pain is a very common clinical manifestation, often seen in patients with early lung cancer. Early chest pain in lung cancer is mild, mainly manifested as dull pain, dull pain, uncertain location, and uncertain relationship with breathing. If the pain persists, it means that the cancer may have affected the pleura.

Early symptoms of lung cancer 5. Shoulder pain - Lung cancer lesions often affect the patient's shoulders and back, causing pain. Peripheral lung cancer often develops posteriorly and upwards, eroding the pleura, involving the ribs and chest wall tissue, thus causing shoulder and back pain. Such patients rarely have respiratory symptoms.

Early symptoms of lung cancer 6. Hoarseness - Hoarseness often occurs after coughing, and is also one of the common early symptoms of lung cancer. Lung cancer metastasis compresses the laryngeal nerve, which can paralyze the vocal cord muscles 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 can appear before the primary lesion.
