                    Endometrial cancer is a disease in which malignant (cancer) cells form in the tissues of the endometrium.
                    The endometrium is the innermost lining of the uterus. The uterus is a hollow, muscular organ in a woman's pelvis. The uterus is where a fetus grows. In most nonpregnant women, the uterus is about 3 inches long.     Cancer of the endometrium is different from cancer of the muscle of the uterus, which is called uterine sarcoma.
