What are the typical symptoms of lung cancer? Lung cancer has 5 main typical symptoms

Symptoms of upper respiratory tract diseases are the main symptoms of lung cancer in the early stage, such as coughing or coughing up blood. In addition, it should be noted that it is best to have sufficient understanding of the symptoms of lung cancer, especially for the high-risk groups of lung cancer. It is recommended to pay attention to regular physical examinations. The following is an introduction to the typical symptoms of lung cancer:

1. Cough: An irritating dry cough appears in the lungs or the nature of the original cough has changed greatly. This may be caused by bronchial spasm caused by the lesions of lung malignant tumors. Cough is one of the main symptoms of early lung cancer.

2. Chest pain: The degree of chest pain among patients varies, and this difference depends not only on the severity of the disease, but also on the patient's specific individual quality.

3. Coughing up blood: This symptom is mainly caused by tumor cells invading the bronchial mucosa. The severity of the disease may vary due to the different physical constitutions of the patients, and the blood in the sputum may also vary. As the disease continues to worsen, once the tumor cells infiltrate the blood vessels, it will cause severe coughing up blood and even endanger the patient's life.

4. Joint symptoms: Changes in body joints are one of the manifestations of lung cancer symptoms. However, in general, the lesions of lung cancer are very small, and the occurrence of arthritis is not easy to be discovered, and it only manifests as migratory arthritis symptoms. The body joints experience burning pain, leading to movement disorders, and there may also be hyperplasia of the periosteum of the tibia and fibula.

5. Finger clubbing: A common early symptom of lung cancer may be finger clubbing, which is when the first section of the fingers and toes become enlarged, the nails become raised and bent, and are often accompanied by pain. This is also an early symptom of lung cancer that cannot be ignored.

The early symptoms of any malignant tumor are generally not obvious, and the same is true for lung cancer. However, it should be noted that it must be differentiated from some special diseases, because there are many diseases that can cause coughing, such as rabbit pneumonia, which is one of the key primary diseases. =
