Early symptoms and signs of lung cancer

Early symptoms of lung cancer include persistent cough, coughing up blood, chest pain, shortness of breath and weight loss. If you experience these symptoms, you should seek medical attention immediately. Early detection and treatment of lung cancer are crucial to improving survival rates. Regular physical examinations are recommended, especially for high-risk groups.

1. Persistent cough is one of the most common early symptoms of lung cancer. This cough usually lasts for weeks or even months and is not easy to relieve. The cough may be accompanied by sputum, which may contain blood. If the cough persists for more than two weeks, especially for smokers or people who are exposed to secondhand smoke for a long time, you should see a doctor as soon as possible for a detailed examination.

2. Coughing up blood is another important early symptom of lung cancer. Coughing up blood may be manifested as blood streaks or large amounts of fresh blood in the sputum. Coughing up blood is usually related to tumors invading the bronchi or pulmonary blood vessels. Once coughing up blood occurs, you should seek medical attention immediately and undergo a chest CT scan or bronchoscopy to determine the cause.

3. Chest pain is one of the common symptoms of lung cancer patients. Chest pain may be dull, stabbing or oppressive, and is usually aggravated by deep breathing, coughing or laughing. Chest pain may be related to tumor invasion of the chest wall or pleura. If chest pain persists or worsens, you should see a doctor as soon as possible for further examination.

4. Shortness of breath is one of the common symptoms of lung cancer patients. Shortness of breath may be related to tumor blocking the airway or pleural effusion. Patients may feel short of breath, especially when they are active. If shortness of breath persists or worsens, you should see a doctor as soon as possible for a detailed examination.

5. Weight loss is one of the common symptoms of lung cancer patients. Weight loss may be related to the tumor consuming energy in the body or affecting appetite. If the weight drops significantly in a short period of time, especially accompanied by other symptoms, you should see a doctor as soon as possible for a detailed examination.

Early detection and treatment of lung cancer are crucial to improving survival rates. It is recommended that high-risk groups, such as long-term smokers, those with a family history of lung cancer, and those who have long-term exposure to asbestos or radioactive substances, undergo regular chest CT scans or low-dose spiral CT examinations. Early detection of lung cancer can improve cure and survival rates through comprehensive treatment methods such as surgery, radiotherapy, and chemotherapy.

Early symptoms of lung cancer include persistent cough, coughing up blood, chest pain, shortness of breath and weight loss. If you have these symptoms, you should seek medical attention immediately. Early detection and treatment of lung cancer are crucial to improving survival rates. Regular physical examinations are recommended, especially for high-risk groups. Early detection and comprehensive treatment can effectively improve the survival rate and quality of life of lung cancer patients.
