Most women with uterine cancer, around 92 percent, have endometrial cancer, or a tumor that develops in the tissues of the uterine lining, called the endometrium. The other primary type, uterine sarcoma, is rare and forms in the muscles or other tissues of the uterus. Symptoms of uterine cancer may differ depending on which type of cancer has developed.

For most women with endometrial cancer, abnormal bleeding is the most common symptom, and the first one they notice. Symptoms of a tumor in the uterus usually affects both premenopausal and postmenopausal women. Other common symptoms of endometrial cancer include:

• Unusual vaginal discharge that does not have signs of blood
• Difficult or painful urination
• Pain during intercourse
• Pain and/or a mass in the pelvic area
• Unintentional weight loss

For most women with uterine sarcoma, unusual vaginal bleeding or spotting is the most common symptom. Other common symptoms of uterine tumors include:

• Frequent urination
• Pain in the abdomen
• A mass (lump or growth) in the vagina
• Feeling full at all times

These signs and symptoms may be caused by conditions other than cancer of the uterus. If you experience any of them, see your doctor to determine its cause.
