Cough is one of the most common reasons people visit a doctor. Most coughs are harmless and settle within a few days or weeks. But what if the cough refuses to go away? Could it be a warning sign of something more serious? Dr Apar Jindal, director, pulmonology and transplant physician, Max Smart Hospital, Saket, shared warning signs of lung cancer.

Early signs of lung cancer
Dr Apar Jindal highlighted that lung cancer often begins quietly. In its early stages, it may cause no symptoms at all, or only a mild cough that is easily mistaken for a lingering infection or the effects of smoking, or, at best, an allergy. Unfortunately, this is one of the reasons many patients are diagnosed only after the disease has advanced.
“A cough that lasts for more than three weeks, changes in nature, or is associated with blood-stained sputum should never be ignored,” said Dr Jindal. It is usually indicative of chronic conditions such as Tuberculosis, lung cancer, or other chronic lung diseases like Interstitial Lung Disease (ILD).

While these symptoms do not always indicate lung cancer, they certainly warrant a thorough medical evaluation.
Causes of lung cancer
Contrary to popular belief, lung cancer is not confined to smokers. Although tobacco remains the leading cause, many patients diagnosed with lung cancer have never smoked. Exposure to second-hand smoke, air pollution, occupational dust and chemicals, toxic gas fumes, and genetic susceptibility can all contribute to the development of the disease.
The advances in diagnostic techniques have made it possible to detect lung cancer much earlier than before. (Pexel)Treatment of lung cancer
Dr Apar Jindal highlighted that the advances in diagnostic techniques have made it possible to detect lung cancer much earlier than before. A detailed medical history, clinical examination, chest imaging, and CT scan are the first steps. If an abnormality is detected, procedures such as bronchoscopy, EBUS, or image-guided biopsy help establish the diagnosis. Molecular testing now allows doctors to identify specific genetic alterations, enabling highly personalized treatment.
Treatment options have also undergone a revolution. Depending on the stage of the disease, patients today may benefit from minimally invasive surgery, advanced radiation therapy, chemotherapy, targeted therapy, immunotherapy, or a combination of these approaches. For many patients diagnosed early, a cure is an achievable goal, and moreover, oral outpatient therapy is a possibility for many patients.
