2. Shortness of Breath
Experiencing shortness of breath after minimal physical exertion is another sign that is often overlooked. Lung cancer can block or narrow airways, making it harder for oxygen to reach the bloodstream. Additionally, tumors may cause fluid to accumulate in the chest cavity (pleural effusion), further restricting lung function.
People often dismiss this symptom as a sign of aging or being out of shape, but it’s important to pay attention to how often it occurs and how much it affects your daily activities. If you find yourself gasping for air or unable to perform tasks you once did with ease, it’s time to see a doctor.
