A chronic cough is often just a sign of something like a cold, allergies, or asthma — but in some cases, it may be a warning sign of lung cancer. According to lung cancer experts, including Dr. Fatemeh Ardeshir-Larijani of Emory University, a cough that lasts longer than 8 to 12 weeks, worsens over time, or comes with other symptoms like coughing up blood, chest tightness, or unexplained weight loss should not be ignored. While many types of cough can happen with lung cancer, the most common is a dry, persistent cough that doesn’t go away with typical treatments.
People with lung cancer may also experience pressure in the chest, shortness of breath, or coughing due to fluid buildup around the lungs. Treatments to ease this kind of cough vary. For some, shrinking the tumor with chemotherapy, immunotherapy, or targeted therapy helps reduce coughing. Others may need fluid drained from their lungs or use home remedies like steam, hydration, or honey to manage the symptom. While only a small number of people with a chronic cough actually have lung cancer, it’s especially important for those at high risk — such as longtime smokers — to speak with their doctor and consider annual lung cancer screenings.
