2. Shortness of Breath
Having difficulties catching your breath is another lung cancer symptom. About 9/10 people with advanced lung cancer tend to experience this symptom. This lung cancer symptom may occur if a lung tumor narrows or blocks an airway, or if the fluid from it, happens to build up in your chest. It can also be as a result of clogged arteries, chronic bronchitis, anemia, a respiratory infection, heavy workouts and even lack of oxygen while in high altitude areas. That being so, if you suddenly start experiencing shortness of breath while you are doing a simple task that you used to do with much ease in the past, don’t take it lightly, consult your doctor. Keep in mind that the shortness of breath may have numerous causes, but if you are at an increased risk for developing lung cancer, you need have to be checked out soonest possible.
