COPD affects an estimated 30 million individuals in the U.S., and over half of them have symptoms of COPD and do not know it. Early screening can identify COPD before major loss of lung function occurs.
Most cases of COPD are caused by inhaling pollutants; that includes smoking (cigarettes, pipes, cigars, etc.), and second-hand smoke.
Fumes, chemicals and dust found in many work environments are contributing factors for many individuals who develop COPD.
Genetics can also play a role in an individual’s development of COPD—even if the person has never smoked or has ever been exposed to strong lung irritants in the workplace.
