Early symptoms and precursors of lung cancer

The early signs of lung cancer are often not obvious, but may include persistent mild respiratory symptoms or systemic discomfort, which may indicate the potential risk of lung cancer. Symptoms include coughing, coughing up blood or blood in sputum, chest pain, difficulty breathing, hoarseness, etc. If you have any discomfort, it is recommended to seek medical attention in time and take appropriate measures under the guidance of a doctor. The details are as follows:

1. Cough: Early lung cancer often presents with cough symptoms, which are mostly dry coughs with little or no sputum. The coughing time is not fixed and has nothing to do with posture. It may be caused by cancer cells irritating the trachea or bronchi. For the treatment of cough, the cause of the cough must be identified first. For cough caused by lung cancer, the main treatment goal is to control the growth and spread of the tumor. At the same time, cough suppressants can be used to relieve symptoms, but they must be used under the guidance of a doctor.

2. Coughing up blood or blood in sputum: Some lung cancer patients may cough up blood or blood in sputum, which is usually caused by the tumor causing necrosis of lung tissue cells and broken capillaries. The amount of hemoptysis and the duration of hemoptysis are related to the degree of vascular damage in cancerous tissue. For the symptom of coughing up blood, hemostasis treatment is needed first, and anti-tumor treatment for lung cancer itself is carried out at the same time, such as surgery, radiotherapy, chemotherapy, etc.

3. Chest pain: Lung cancer may cause chest pain. In the early stage, chest pain is mild, mainly dull pain and dull pain. The pain site is not fixed, but if the pain persists, it may indicate that the cancer has affected the pleura. The treatment of chest pain should be based on the cause. For chest pain caused by lung cancer, the main treatment goal is to control the growth and spread of the tumor. At the same time, analgesics can be used to relieve symptoms, but they must be used under the guidance of a doctor.

4. Dyspnea: Lung cancer may cause dyspnea because the tumor blocks the airway or compresses the lung tissue, resulting in limited gas exchange. Lung cancer may also cause pleural effusion or pleural thickening, further aggravating dyspnea. Treatment of dyspnea needs to be targeted at the cause, such as controlling the growth and spread of the tumor through surgery, radiotherapy or chemotherapy. At the same time, auxiliary treatment methods such as oxygen inhalation and bronchodilators can be used to relieve symptoms.

5. Hoarseness: Hoarseness is an early feature of lung cancer, which may be caused by direct invasion of the mediastinum or lymph node growth and involvement of the ipsilateral recurrent laryngeal nerve. This type of hoarseness is usually accompanied by coughing, and is different from hoarseness caused by common pharyngitis, colds, etc. The treatment of hoarseness needs to be targeted at the cause, such as controlling the growth and spread of the tumor through surgery, radiotherapy or chemotherapy. At the same time, methods such as voice rehabilitation training can be used to help patients restore their voice function.

Early symptoms and precursors of lung cancer may indicate the risk of lung cancer. Therefore, when these symptoms occur, you should seek medical attention for professional examination and treatment in time.
