10 Symptoms of Non-Small Cell Lung Cancer

Shortness of breath. Difficulty breathing is often ignored at first. Patients may think it comes from aging, low physical activity, or even heart problems. But NSCLC can narrow the airways or cause fluid to accumulate in the chest, making it harder to breathe. Initially, shortness of breath happens during physical activity, like climbing stairs, but later it can occur even while resting.

If shortness of breath continues or gets worse without clear cause, it should be carefully evaluated.
