Risk Factors

The most common cause of endometrial cancer is an excess of the hormone estrogen compared to the hormone progesterone in the body. This imbalance causes the lining of the uterus to thicken, which can result in the formation of cancer cells. Risk factors can include:

• Age — more common after age 50

• Obesity

• Estrogen replacement therapy without the use of progesterone

• Polycystic ovarian syndrome, a hormonal imbalance

• Tamoxifen — a drug for the treatment of breast cancer

• Never having children and infertility

• Early menstruation (before age 12) or late menopause

• History of benign growths of the uterine lining or endometrial polyps

• Family history of colon cancer

• Personal history of breast or ovarian cancer

• Diabetes and high blood pressure
