Uterine sarcoma is a rare cancer of the muscle and connective tissues of the uterus, which is also called the womb. The term “sarcoma” refers to cancers that start in tissue such as the muscle, fat, bone and fibrous tissue. The cancers that start in cells, called epithelial cells, that line or cover most organs, are called “carcinomas”.
Uterine sarcoma is different from endometrial cancer, which is cancer of the lining of the uterus.
According to the American Cancer Society, uterine sarcoma accounts for about 4% of uterine malignant cancers, with about 1,500 new cases a year.
