Persistent Cough? It Could Signal Lung Cancer

A cough that persists for more than three weeks requires medical attention as it can be an indicator of serious underlying health issues. Dr. Apar Jindal, director of pulmonology and transplant physician at Max Smart Hospital, Saket, has identified specific warning signs related to lung health. These include a cough that changes in nature or is associated with blood-stained sputum, which should never be disregarded.

These persistent cough symptoms are often indicative of chronic conditions. Among them are tuberculosis, lung cancer, and other chronic lung diseases such as Interstitial Lung Disease (ILD). Dr. Jindal emphasizes that lung cancer frequently begins subtly, with early stages often showing no symptoms or only a mild cough easily mistaken for common ailments. This lack of early, clear signs contributes to many diagnoses occurring only after the disease has advanced.
