Sarcoma of the uterus, a very rare kind of cancer in women, is a disease in which cancer (malignant) cells start growing in the muscles or other supporting tissues of the uterus. Sarcoma of the uterus is different from cancer of the endometrium, a disease in which cancer cells start growing in the lining of the uterus. Women who have received therapy with high-dose X-rays (external-beam radiation therapy) to their pelvis are at a higher risk to develop sarcoma of the uterus. These X-rays are sometimes given to women to stop bleeding from the uterus.

A doctor should be seen if there is bleeding after menopause (the time when a woman no longer has menstrual periods) or bleeding that is not part of menstrual periods. Sarcoma of the uterus usually begins after menopause.
