Cancer of the uterus is a malignant growth of cells in the endometrium, the lining of the uterus. Babies develop in the uterus, and menstrual blood comes from the uterus. This type of cancer is also called uterine or endometrial cancer.
Uterine cancer is one of the most common cancers among women.
It occurs most often in women between the ages of 50 and 70. The cause of cancer of the uterus is not known. However, you are at greatest risk of having this type of cancer if you have a condition that causes your body to produce a lot of the hormone estrogen and you have gone through menopause. Having a high level of estrogen in your body does not create a high risk of cancer by itself. It is a risk only when your body also does not have enough of another hormone called progesterone.
