A biopsy is the removal of a sample of tissue or cells so that they can be examined by a pathologist, usually under a microscope. A specialist trained to examine a sample of tissue for signs and extent of disease under a microscope is called a pathologist.
A biopsy is performed to look for a disease or condition such as an infection, inflammation, or cancer. Some commonly biopsied organs include bone marrow, liver, kidney lymph nodes, skin, esophagus, stomach and other parts of the digestive tract, and muscle tissue.
