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.

An endometrial biopsy is used to find endometrial cancer. Endometrial cancer might explain unexpected vaginal bleeding, particularly if bleeding occurs after menopause.
