Did you know cancer is responsible for 1 in 4 deaths in the United States? Or that cancer is the second leading cause of death in the U.S?
Emphysema is one type of chronic obstructive pulmonary disease (COPD), a category of lung diseases that also includes chronic bronchitis and bronchiectasis.
Emphysema is caused by damage to the alveoli, the tiny air sacs in the lung where the exchange of oxygen and carbon dioxide takes place. With emphysema, damage to the alveoli results in air becoming trapped, causing them to expand and rupture.
