Uterine sarcoma, a soft-tissue sarcoma, accounts for 5 percent of cases and involves the muscle of the uterus. Uterine sarcoma may spread more quickly than endometrial cancer.
To determine if uterine sarcoma is present, your Mayo Clinic doctor will take a detailed medical history and conduct a complete physical exam. During a pelvic exam, the doctor will feel for lumps or abnormalities in your uterus. The Mayo Clinic Molecular Diagnostic Laboratory helps doctors diagnose sarcomas quickly and accurately.
As with other forms of uterine cancer, your doctor may recommend a combination of surgery, radiation therapy and chemotherapy. Depending on the tumor, your doctor may recommend different surgery, chemotherapy and radiation than that given for other types of uterine cancer.
