When a small sample of tissue is taken from the body and sent to a clinical laboratory to be examined or studied, it is called a biopsy. Biopsies are performed to diagnose diseases, such as cancer, by analyzing tissue samples under a microscope. This procedure provides critical information about the presence and extent of diseases.
