The main symptom of endometrial cancer is unusual vaginal bleeding. This occurs in almost all people with endometrial cancer. The bleeding may include:

• Changes in the kind of bleeding during periods, such as a very long period or heavy bleeding.
• Bleeding between periods.
• Any vaginal bleeding after menopause.

For most people, abnormal vaginal bleeding is the only symptom they have. But other symptoms may include:

• Vaginal discharge that isn't blood.
• Pain when urinating.
• Pain during sex.
• Pain, pressure, or a lump in the pelvic area or lower belly (lower abdomen).
• Losing weight without trying.

Tell your doctor if you have any unusual bleeding from the vagina. Tell the doctor if you have any bleeding at all after menopause. Even if it is just a bit of spotting or slight bloody discharge, it is very important to let your doctor know, as this small amount of bleeding may be the only sign of a problem.

Some people develop endometrial cancer while they are entering menopause. During this time, periods may get heavier or lighter. This may not be a symptom of menopause. Make sure to tell your doctor about any change in vaginal bleeding during this time.

Some of these symptoms may be caused by other health problems. But it is important to see your doctor if you have these symptoms. Only a doctor can tell if you have cancer.
