Biopsy
Definition: A biopsy is the removal of a small sample of tissue for examination under a microscope by a pathologist.
There are two types of lung biopsies:
# Surgical
In a lung biopsy, a small piece of lung tissue is removed through a surgical incision in the chest. The abnormal results may indicate cancer, benign tumors, lung diseases, and certain lung infections.
# Non-surgical / Needle
When the abnormal condition is near the surface of the lung, in the tissues surrounding
the lungs, or on the chest wall, a lung biopsy is performed using a biopsy needle.
This is performed when a lung infection is suspected and no other tests have identified the cause of the infection
