16408 Uterine Sarcoma
Informed by recognized medical guidance
Overview
Uterine sarcoma is a rare type of cancer that starts in the muscle or connective tissue of the uterus (womb). It is different from the much more common cancer that starts in the lining of the uterus, called endometrial cancer.
Key facts
- Uterine sarcoma is rare, making up less than 3 in every 100 cancers of the uterus.
- It can grow quickly, so early medical check-up is important.
- The most common first sign is unusual vaginal bleeding, especially after menopause.
- Treatment usually begins with surgery to remove the uterus, and may be combined with other treatments.
No. Uterine sarcoma is a rare cancer. Most cancers of the uterus are endometrial cancers, not sarcomas.
It can affect women of any age, but it is most often found in women after menopause, typically between the ages of 45 and 60.
Symptoms
- Sudden, very heavy vaginal bleeding that soaks a pad or more every hour
- Feeling faint, dizzy, or extremely weak
- Sudden, severe pelvic or abdominal pain
- ⚠New or worsening pelvic pain
- ⚠Bleeding that is heavier or lasts longer than is normal for you
- ⚠A fever or foul-smelling vaginal discharge
Common symptoms
- Unusual vaginal bleeding or discharge
- Bleeding after menopause
- Pelvic pain or pressure
- A feeling of fullness or a lump in the pelvic area
- Periods that are heavier, longer, or more frequent than usual
Symptoms in older adults
- Bleeding after menopause
- Unexplained tiredness or weakness from blood loss
- Pelvic pain or a sense of pressure that does not go away
Causes
Main causes
- The exact cause is unknown. It starts when cells in the muscle or connective tissue of the uterus grow out of control.
- Some cases are linked to changes in certain genes, such as those inherited in conditions like Lynch syndrome.
Risk factors
- Age older than 50
- Past treatment with radiation to the pelvic area
- Inherited conditions such as Lynch syndrome or hereditary retinoblastoma
- Being of Black ethnicity (some studies show a slightly higher risk)
When to see a doctor
See a doctor urgently if:
- Make an urgent appointment if you have any unusual vaginal bleeding, especially after menopause.
- Seek care promptly for new pelvic pain, pressure, or a noticeable lump.
Book a routine appointment if:
- Book a routine visit if you have period changes that last more than a few weeks.
- If you have any concerning symptom that does not settle after a week, talk to your doctor.
Diagnosis
A doctor will start by asking about your symptoms and doing a pelvic exam. If they suspect a problem in the uterus, they will usually refer you to a gynaecologist, a doctor who specialises in female health.
Tests that may be done
- Pelvic ultrasound – a painless scan using sound waves to look at the uterus.
- MRI (magnetic resonance imaging) – a detailed picture of the pelvic area.
- Endometrial biopsy – a small sample of tissue is taken from the lining of the uterus for testing.
- Hysteroscopy with biopsy – a thin camera is inserted into the uterus so the doctor can see the inside and take a tissue sample.
What to expect at your appointment
If a biopsy is done, the tissue sample is sent to a laboratory. Results may take a week or more. If cancer is found, your medical team will talk with you about the type, grade, and stage, and together you will plan the next steps.
Treatment
Treatment for uterine sarcoma depends on the type, size, stage, and spread of the tumour, as well as your overall health and preferences. You will have a team of specialists who create a plan with you.
Self-care at home
- Ask your care team to explain each step in words you understand.
- Bring a trusted friend or relative to medical appointments for support.
- Write down your questions before each appointment.
- Be kind to yourself, rest when you need to, and accept help from others.
Medical treatments
The main treatment is surgery to remove the uterus and often the fallopian tubes and ovaries. Depending on the situation, other treatments may include radiation therapy (high-energy rays to kill cancer cells), chemotherapy (medicines to stop cancer cells growing), and targeted or hormonal therapies. Your care team will discuss which options are most suitable for you.
When is surgery considered?
Surgery is usually the first step for early-stage uterine sarcoma. For some women, surgery alone may be enough. For more advanced disease, surgery is often combined with other treatments.
Living with this condition
Living with a rare cancer can feel overwhelming. Take things one day at a time, keep a symptom diary, and let your support network know what you need and how they can help.
Lifestyle tips
- Prioritise rest and allow your body to heal after treatment.
- Build a gentle daily routine that includes light activity, such as short walks.
- Stay connected with friends, family, or a support group.
- If you feel anxious or low, talk to your care team about counselling or mental health support.
Diet and exercise
A balanced diet with plenty of vegetables, fruit, whole grains, and protein can help you keep up your strength. Gentle exercise, such as walking or yoga, can boost your mood and energy. Always check with your doctor before starting anything new.
Mental health and emotional wellbeing
A cancer diagnosis can bring anxiety, sadness, and stress. These feelings are normal. Many people find it helpful to speak with a psychologist or join a cancer support group where others understand what you are going through.
Prevention
There is no known way to prevent uterine sarcoma. Because it is so rare, most people do not need to worry about it. The most important thing is to be aware of changes in your body and see a doctor early if something feels off.
Screening programmes
There is no routine screening test for uterine sarcoma. The best approach is to know what is normal for your body and to report any unusual bleeding or pain to a doctor promptly.
Complications
If left untreated
- The cancer can spread to other parts of the body, such as the lungs, liver, or bones.
- Heavy bleeding can lead to anaemia, which causes tiredness and weakness.
- A growing tumour can press on nearby organs, causing pain and digestive problems.
Long-term outlook
The outlook is personal and depends on the exact type of sarcoma, the size of the tumour, and whether it has spread. Many women are diagnosed early enough for treatment to be successful. Even in more advanced situations, treatments can help control the cancer and support a good quality of life. Your medical team will talk honestly with you about what to expect.
