5 types of early symptoms of lung cancer

In today's living environment, there are more and more people smoking, and the current environmental pollution is serious, which leads to an increase in the number of lung cancer patients. Patients should find the symptoms of lung cancer in time and treat them, so as to recover as soon as possible.

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. 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.

3. 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.

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. 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, in which 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.
