Asthma and Lung Cancer can both cause coughing, breathing difficulty, and chest discomfort, but doctors use symptom patterns and medical tests to differentiate them. Asthma often involves wheezing, allergy triggers, and episodes that improve with medication, while lung cancer may present with persistent cough, unexplained weight loss, chest pain, coughing up blood, or long-term smoking history.
Imaging tests, lung function tests, and biopsies help confirm the diagnosis. Experts stress that persistent or worsening respiratory symptoms should never be ignored, especially in individuals exposed to smoking, pollution, or occupational lung irritants.
