What are the typical symptoms of lung cancer? 5 typical symptoms of lung cancer

Expert introduction: Irritating dry cough is a typical symptom of upper respiratory tract diseases, and the most common symptom of lung cancer is also the same. In addition, as the disease progresses, the patient's cough becomes more severe, and blood may appear in the sputum. Once middle-aged and elderly people have blood in their sputum, lung cancer should be suspected. The following are 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, when the lesions of lung cancer are very small, 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 fibular periosteal hyperplasia may also occur.

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.

Early lung cancer symptoms are usually not obvious and atypical. Most of them are symptoms of respiratory diseases, such as coughing, which are easily ignored by patients. One thing to remember is that once a malignant tumor has obvious symptoms, it is usually in the middle or late stage of the disease. It is recommended that the elderly have regular physical examinations.
