Lung cancer is the uncontrolled growth of abnormal cells that start off in one or both lungs usually in the cells that line the air passages. The abnormal cells do not develop into healthy lung tissue, they divide rapidly and form tumours. Bronchitis is an inflammation of the lining of your bronchial tubes, which carry air to and from your lungs. Emphysema is a lung condition that causes shortness of breath. In people with emphysema, the air sacs in the lungs (alveoli) are damaged.
