Endometrial cancer. Endometrial cancer is the most common form of uterine cancer. Because the endometrium is part of the uterus, endometrial cancer is often referred to as uterine cancer. Endometrial cancer is the most commonly diagnosed gynecologic cancer (which includes cancers of the uterus, cervix, ovaries, vulva, vagina and fallopian tubes). Endometrial cancer forms when cells in the inner lining of the uterus (endometrium) begin to grow out of control.
An endometrial biopsy is most often performed to help determine the cause of abnormal uterine bleeding. It can also be done to help evaluate the cause of infertility, test for uterine infections, and even monitor the response to certain medications.
