Explanation:
Emphysema is a type of chronic obstructive pulmonary disease. The air sacs in the lungs become damaged and stretched. This results in a chronic cough and difficulty breathing.
Smoking is the most common cause, but emphysema can also be genetic. There is no cure, but quitting smoking can stop emphysema from getting worse.
In the United States (U.S.), 3.5 million people, or 1.5 percent of the population, received a diagnosis of emphysema in 2016. The number of deaths involving emphysema was 7,455, or 2.3 people in every 100,000.
