When should I see a doctor if I suspect lung cancer symptoms?

If you suspect symptoms of lung cancer, you should see a doctor as soon as possible, especially if you experience any of the following: Persistent cough that doesn’t go away or worsens over time Coughing up blood or rust-colored sputum Shortness of breath or wheezing Chest pain that worsens with deep breathing, coughing, or laughing Unexplained weight loss or loss of appetite Fatigue or weakness Hoarseness or changes in your voice Frequent respiratory infections such as bronchitis or pneumonia Early detection is crucial because lung cancer symptoms often appear in later stages. If you are a smoker, have a history of smoking, or have been exposed to secondhand smoke, asbestos, or other carcinogens, it’s especially important to seek medical advice promptly. Your doctor may recommend imaging tests (such as an X-ray or CT scan) or further evaluation to determine the cause of your symptoms. Don’t wait—early diagnosis can improve treatment options and outcomes.
