10 Symptoms of Non-Small Cell Lung Cancer

A persistent cough. In many cases, cough is a symptom of colds, flu, or bronchitis. But when a cough lasts for weeks or even months without improvement, it can be a sign of NSCLC. The cough may be dry at first, similar to allergies, or produce mucus, resembling chronic bronchitis. Over time, the intensity may increase. Sometimes the sputum can become rust-colored or contain blood streaks.

A chronic cough that refuses to go away despite treatment is always a reason to consult a doctor.
