For medical questions, we encourage you to review our information with your doctor.
A risk factor is anything that increases your chance of getting a disease such as cancer. Different cancers have different risk factors. Some risk factors, like smoking, can be changed; others, like a person’s age or family history, can’t.
Having a risk factor, or even several, does not mean that you will get the disease. And many people who get the disease may have few or no known risk factors.
Although this cancer is very rare, a few risk factors are known to increase a woman's risk of developing a uterine sarcoma.
Radiation to the pelvis can increase your risk for developing uterine sarcoma. This has been seen sometimes after someone has had radiation to treat cervical cancer or rectal cancer. These cancers usually are diagnosed 5 to 25 years after the radiation treatment.
Women who have had a type of eye cancer called congenital (heritable) retinoblastoma as a child have an increased risk of soft tissue sarcomas, including uterine sarcomas.
A rare family cancer syndrome called hereditary leiomyomatosis and renal cell cancer (HLRCC) has been linked to an increased risk of uterine sarcomas.
Although the risk is small, women taking tamoxifen to prevent or treat breast cancer have an increased risk of developing uterine sarcoma. These sarcomas often show up 2 to 5 years after starting tamoxifen. If you are taking tamoxifen, doctors recommend getting regular pelvic exams and more testing if you are having abnormal bleeding from the uterus.
