Cancer is a disease in which cells in the body grow out of control. Cancer is always named for the part of the body where it starts, even if it spreads to other body parts later.
When cancer starts in the uterus, it is called uterine cancer. The uterus is the pear-shaped organ in a woman's pelvis (the area below your stomach and in between your hip bones). The uterus, also called the womb, is where the baby grows when a woman is pregnant. The most common type of uterine cancer is also called endometrial cancer because it forms in the lining of your uterus, called the endometrium.
When uterine cancer is found early, treatment works best.
