Persistent Cough and Hoarseness: Early Warning Signs of Lung Cancer You Shouldn’t Ignore
Persistent Cough — A Signal Not to Overlook
Coughing is a common defense mechanism of the respiratory system, often caused by colds, allergies, or infections. However, when a cough lasts more than eight weeks without improvement, it could indicate an underlying lung issue. Early-stage lung cancer often presents with subtle or no symptoms, and a persistent cough may be a sign that cancer cells are affecting the airways. Especially if accompanied by coughing up blood, chest pain, or shortness of breath, prompt medical evaluation is crucial.
Individuals who smoke, are frequently exposed to carcinogens like asbestos or coal dust at work, or have a family history of lung cancer should be particularly alert to any persistent coughing.
