Document:
As pulmonologists, our physicians possess specialized knowledge and skill in the diagnosis and treatment of pulmonary (lung) conditions and diseases.
Pulmonology is classified as an internal medicine subspecialty. Because pulmonologists encounter a variety of clinical problems, they must have knowledge of internal medicine and other specialties in order to obtain certification.
Some conditions that a pulmonologist will diagnose and treat include asthma, chronic cough, COPD (chronic obstructive pulmonary disease), lung cancer, and sarcoidosis.
Pulmonologists may serve as consultants to other physicians as well as provide long-term care to patients with chronic conditions.
Alex E. Lechin, M.D., F.C.C.P., F.A.A.S.M.
Dr. Lechin is certified by the American Board of Internal Medicine (ABIM).
