A biopsy is a diagnostic tool in which a sample of tissue taken from the body is examined more closely, often if cancer is suspected. Biopsies entail using a sharp tool, such as a needle, to remove a small part of tissue that is then examined in a pathology lab. Biopsies are done in a doctor's office or in a hospital, if guidance by an imaging machine is necessary. In most cases, sedating and pain-relief medicines are given to reduce any discomfort. The time it takes to get results from a biopsy can vary.
