Endometrial Cancer

Endometrial cancer is a type of cancer that begins in the uterus. The uterus is the hollow, pear-shaped pelvic organ in women where fetal development occurs.
Endometrial cancer begins in the layer of cells that form the lining (endometrium) of the uterus. Endometrial cancer is sometimes called uterine cancer. Other types of cancer can form in the uterus, but they are much less common than endometrial cancer.
Endometrial cancer is often detected at an early stage because it frequently produces abnormal vaginal bleeding, which prompts women to see their doctors. If endometrial cancer is discovered early, removing the uterus surgically often eliminates all of the cancer.

Endometrial Cancer Symptoms

Signs and symptoms of endometrial cancer may include:

• Vaginal bleeding after menopause
• Prolonged periods or bleeding between periods
• An abnormal, watery or blood-tinged discharge from your vagina
• Pelvic pain
• Pain during intercourse

When to see a doctor

Make an appointment with your doctor if you experience any signs or symptoms that worry you, such as vaginal bleeding or discharge not related to your periods, pelvic pain, or pain during intercourse.

Causes

Doctors don't know what causes endometrial cancer. What's known is that something occurs to create a genetic mutation within cells in the endometrium — the lining of the uterus. The genetic mutation turns normal, healthy cells into abnormal cells. Healthy cells grow and multiply at a set rate, eventually dying at a set time. Abnormal cells grow and multiply out of control, and they don't die at a set time. The accumulating abnormal cells form a mass (tumor). Cancer cells invade nearby tissues and can separate from an initial tumor to spread elsewhere in the body (metastasize).
