Of the types of cancer that affect women’s reproductive systems, endometrial cancer — a type of uterine cancer — is the most common. It’s important to understand the common risk factors for endometrial cancer and how you may be able to lower your risk of getting the disease.

Endometrial cancer is any cancer that affects the lining of the uterus. The most common type is endometrioid adenocarcinoma, which forms in the glands of the uterus.
According to the CDC, risk factors for endometrial cancer include, but are not limited to the following:
Being older than 50
Being postmenopausal
Early menstruation (starting your period early)
Late menopause

Being overweight or having obesity
Never having been pregnant, especially if you had trouble getting pregnant
Having a history of fewer than five periods per year
Taking estrogen as a standalone hormone replacement drug or taking certain drugs to prevent or treat breast cancer
Family history of endometrial, colon or ovarian cancer
Personal history of breast or ovarian cancer
Genetics, including a condition known as Lynch syndrome, which increases the risk of endometrial, colon and ovarian cancers
Having type 2 diabetes
Having endometrial hyperplasia (thickening of the endometrium)

Most cases of endometrial cancer occur in postmenopausal women. They are at greater risk of getting endometrial cancer because a hormone imbalance causes more estrogen than progesterone in the body, which can increase the chance of getting the disease.
In the United States, endometrial cancer is the most common cancer of the female reproductive organs. The average age for diagnosis is 60, and the majority of women are diagnosed between ages 55 and 64.
White women are slightly more likely to be diagnosed with endometrial cancer than Black women, followed by Hispanic women, Asian/Pacific Islander women and American Indian/Alaskan Native women.
Black women are nearly twice as likely to die from endometrial cancer than women of any other race because they are generally diagnosed later with more advanced stages of the disease, have surgery less often and may be more likely to have risk factors.
The most common symptom of endometrial cancer is abnormal menstrual bleeding. This includes any irregular menstrual bleeding, spotting or bleeding between periods. For postmenopausal women, any bleeding is considered abnormal. More-advanced symptoms may include:
Pain in the lower abdomen or cramps in the pelvis
Bloating or feeling full quickly when eating
Changes in bowel or bladder habits

These are not all the possible symptoms of endometrial cancer and may also be indicative of other conditions. Talk to your healthcare provider about any symptoms of concern.

Endometrial cancer is diagnosed through a pelvic exam, a transvaginal ultrasound, a hysteroscopy, dilation and curettage (D&C), and/or a biopsy.
Endometrial cancer is often treated first with surgery. Depending on the location and type of cancer, surgery may remove cancerous tissues, the uterus (a hysterectomy), the fallopian tubes and ovaries (a bilateral salpingo-oophorectomy), and/or lymph nodes around the pelvis.
Other types of treatments may be used after surgery or in place of surgery for younger women who want to keep their fertility or prevent early menopause. This includes radiation therapy, chemotherapy, hormone therapy, targeted therapy and immunotherapy.
There are no specific screening tests for endometrial cancer. The best thing to do is be aware of the risks and symptoms, and focus on lowering your risk factors.
Ways you may be able to help lower your risk of getting endometrial cancer:
Maintain a healthy weight
Engage in physical activity. Be sure to always check with your healthcare provider before starting a new exercise plan.
Get annual checkups and report any unusual symptoms — including abnormal menstrual bleeding — to your healthcare provider as soon as possible
Speak to your healthcare provider for more information about taking progesterone if you take estrogen
