Endometrial Biopsy
An endometrial biopsy is a way for your doctor to take a small sample of the lining of the uterus (endometrium). The sample is looked at under a microscope for abnormal cells. An endometrial biopsy helps your doctor find many problems in the endometrium. It also allows your doctor to check to see if your body's hormone levels that affect the endometrium are in balance.
An endometrial biopsy may be done for various reasons. When a woman is having a hard time becoming pregnant, an endometrial biopsy may be done to see whether the lining of her uterus can support a pregnancy. An endometrial biopsy may also be done to find the cause of abnormal uterine bleeding, to check for overgrowth of the lining (endometrial hyperplasia), or, to check for cancer.
