Uterine sarcoma is a type of cancer where cancer cells form in the muscles of the uterus or connective tissues that support or surround the uterus. This type of cancer is rare, and the tumors are typically low-grade. The cancer cells don’t look very abnormal and tend to grow slowly.
In general terms, some cancers are “carcinomas” while some are “sarcomas.” Uterine carcinoma affects the glandular tissue of the uterus lining, while uterine sarcoma affects the smooth muscle of connective tissue of the uterus. There are three types of uterine sarcoma:
- Uterine leiomyosarcoma
- Endometrial stromal sarcoma
- Undifferentiated sarcoma
It is known that exposure to xrays may increase the risk of uterine sarcoma.
Signs and symptoms of uterine sarcoma include:
- Unusual bleeding, spotting, or discharge that is not related to menstrual periods or menopause
- Abdominal fullness
- Pain in the abdomen or pelvic area
- Pain during sexual intercourse
- Frequent, difficult, or painful urination
