Biopsy – The removal of a sample of tissue from the body for examination under a microscope. Therefore, usually only very small samples are needed. Sometimes, it is enough just to scrape over an area. This is the case with cell examinations of the cervix (neck of the womb). Sometimes, a biopsy can be taken with forceps through a tube known as an endoscope, and in other cases, for instance, a liver or kidney biopsy, the biopsy is taken using a large hypodermic needle.
