All About Emphysema

According to the National Heart, Lung and Blood Institute (NHLBI), emphysema affects over 2 million Americans, the majority of whom are 50 years old and over.

Emphysema is a slow killer, progressing gradually over a period of many years. The damage done to the lungs with emphysema is permanent and irreversible, but if a person stops smoking early on in the disease, it may be possible to arrest further development and improve one's quality of life.
