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.
Biopsy is a medical procedure where a sample of tissue is taken from a patient for examination and diagnosis of an illness or medical condition. Many different biopsy procedures exist depending on the location of the tissue under investigation.
