Outlook (Prognosis) Your prognosis depends on the type and stage of uterine sarcoma you had when treated. For cancer that has not spread, at least 2 out of every 3 people are cancer-free after 5 years. The number drops once the cancer has started to spread and becomes harder to treat.Uterine sarcoma is often not found early, therefore, the prognosis is poor. Your provider can help you understand the outlook for your type of cancer. Possible Complications Complications may include:A perforation (hole) of the uterus may occur during a D and C or endometrial biopsy Complications from surgery, radiation, and chemotherapy When to Contact a Medical Professional See your provider if you have any symptoms of uterine cancer. Prevention Because the cause is unknown, there's no way to prevent uterine sarcoma. If you have had radiation therapy in your pelvic area or have taken tamoxifen for breast cancer, ask your provider how often you should be checked for possible problems.Open ReferencesReferencesBoggess JF, Kilgore JE, Tran A-Q.
