An endometrial biopsy is a quick, in-office procedure that collects a small tissue sample from the lining of the uterus (endometrium) for examination under a microscope. This test helps evaluate the cause of abnormal uterine bleeding, detect precancerous or cancerous cells, and assess hormonal effects on the uterine lining. During the procedure, a thin, flexible instrument is gently inserted through the cervix to obtain the sample. While you may feel brief cramping, the procedure is typically well-tolerated and takes only a few minutes.
