The lungs are an organ through which blood, after circulating throughout the body, returns to the heart and then flows into the lungs. This makes the lungs prone to metastasis from cancers originating in other parts of the body. However, lung cancer refers specifically to cancer that first develops in the lungs (primary lung cancer), rather than cancer that has metastasized from elsewhere. Common symptoms include coughing, sputum, blood in the sputum, chest pain, and shortness of breath. Early detection is critical, and smoking is the main cause. Lung cancer is diagnosed through imaging tests and tumor marker tests, with treatments including surgery, radiation therapy, and chemotherapy.
Early Detection of Lung Cancer
- Regular Health Screenings: Regular health checkups can help detect early signs of lung cancer. If you have a history of smoking, consider regular chest X-rays or CT scans.
- Self-Check: Be mindful of the following symptoms:
- Persistent Cough: Especially if there is blood in the sputum, immediate attention is required.
- Shortness of Breath: If you experience difficulty breathing during daily activities, consult a doctor.
- Chest Pain: If you have chest pain or a feeling of pressure, seek medical evaluation promptly.
- Imaging Tests: Chest X-rays and CT scans are useful tools for detecting lung abnormalities. Regular screening is recommended for those at high risk.
- Tumor Marker Tests: Blood tests that measure specific proteins, such as CEA or CYFRA 21-1, can help assess the risk of lung cancer.
- Avoid Smoking: Smoking is the leading cause of lung cancer. Quitting smoking is essential for reducing the risk.
Early detection improves treatment success and increases survival rates. If you experience any concerning symptoms, consult a doctor immediately.
