Uterine and Endometrial Cancer 101

On this page you will learn about symptoms of uterine cancer, diagnosis, and treatment options. We hope this information will help you prepare for a discussion with your gynecologist or a Gynecologic Oncologist.

 

What is Uterine Cancer?

Cancer is a disease in which cells in the body grow out of control. Cancer is usually named for the part of the body where it starts, even if it spreads to other body parts later.

 

When cancer starts in the uterus, it is called uterine cancer. The uterus is the pear-shaped organ in the pelvis (between your hip bones). The uterus, also called the womb, is where the baby grows when a during pregnancy.

 

The most common type of uterine cancer is also called endometrial cancer because it forms in the lining of your uterus, called the endometrium.

A rare type of uterine cancer is called uterine sarcoma. It forms in the muscles or tissues that support the uterus. 

 

Anyone with a uterus is at risk for uterine cancer, and the risk increases with age. Most uterine cancers are found in those who are going through or who have gone through menopause—the time of life when menstrual periods stop.

Uterine cancer is the most common gynecologic cancer.

 

The Foundation for Women's Cancer has brochures in English, Spanish, and Chinese to help you understand your cancer:

According to the American Cancer Society, in 2025, 69,120 individuals will be diagnosed with uterine cancer in the United States. Uterine cancer has a high survival rate with 8 out of 10 individuals surviving uterine cancer for more than five years from diagnosis date. 

What causes Uterine Cancer?

Endometrial risk factors affect the balance between estrogen and progesterone in the body. This imbalance causes abnormal growth in the endometrium until it develops into cancer.

How do I know if I have uterine cancer? 

There is no standard or routine screening test for endometrial cancer, which is why you should listen to your body and follow up if you have any of the common signs and symptoms outlined below. Pap Smears do NOT screen for uterine cancer.

The most common warning sign for any uterine cancer is abnormal vaginal bleeding.

 

Recognition of this symptom often affords an opportunity for early diagnosis and treatment. In postmenopausal people, any bleeding or spotting is abnormal and should prompt immediate evaluation by a gynecologist.

 

Premenopausal reproductive age people who do not have regular monthly periods or who have excessive duration and/or quantity of bleeding each month should also be evaluated by a gynecologist as these can be symptoms of uterine cancer.

Increasing abdominal girth (bloating), pelvic pain or increasing urinary frequency, difficulty passing stool, or feeling full quickly can also be warning signs of uterine cancer. 

When a person experiences concerning symptoms, they should discuss these symptoms with their doctor, preferably a gynecologist.

If uterine cancer is suspected or diagnosed, it is important to seek care from a gynecologic oncologist—medical doctors with specialized training in treating gynecologic cancers who can manage your care from diagnosis to completion of treatment.

Symptoms, Risk Factors, and Screening

Symptoms

  • Vaginal discharge or bleeding that is not normal for you.

  • Bleeding may be abnormal because of how heavy it is or when it happens, such as after you have gone through menopause and between periods.

  • Bleeding is never normal after your periods stop.

  • Premenopausal reproductive age people who do not have regular monthly periods or who have excessive duration and/or quantity of bleeding each month should also be evaluated by a gynecologist as these can be symptoms of uterine cancer.

  • Other symptoms include pain or pressure in your pelvis, increasing abdominal girth, increasing urinary frequency, or difficulty passing stool. These symptoms can sometimes be associated with an enlarging uterus.

 

If you have bleeding that is not normal for you, especially if you have already gone through menopause, or have any one of these symptoms listed above for more than two weeks in any month, see your doctor, preferably a gynecologist, right away. These symptoms may be caused by something other than cancer, but the only way to know is to see your doctor.

Risk Factors and Causes

There is no way to know for sure if you will get uterine cancer. Some women get it without being at high risk. However, several factors may increase the chance that you will get uterine cancer, including if you:

  • Are older than 50.

  • Have obesity.

  • Take estrogen by itself (without progesterone) for hormone replacement during menopause.

  • Have had trouble getting pregnant or have had fewer than five periods in a year before starting menopause.

  • Take tamoxifen, a drug used to prevent and treat certain types of breast cancer.

  • Have close family members who have had uterine, colon, or ovarian cancer.

  • Have a genetic mutation (change) that raises your risk, including BRCA1 or BRCA2, or one associated with Lynch syndrome. Note that only 5-10% of endometrial cancers are the result of an inherited mutation

Screening

There are no screening tests for uterine cancer in women who do not have any signs or symptoms. The Pap test does not screen for uterine cancer, it screens for cervical cancer.

Screening is when a test is used to look for a disease before there are any symptoms. Diagnostic tests are used when a person starts having symptoms. The purpose of diagnostic tests is to find out, or diagnose, what is causing the symptoms. Diagnostic tests also may be used to check a person who is considered at high risk for cancer.

Since there is no simple and reliable way to screen for any gynecologic cancers except cervical cancer, it is especially important to recognize warning signs and learn what you can do to reduce your risk.

If you have symptoms, your doctor may perform an endometrial biopsy or a transvaginal ultrasound. These tests can be used to help diagnose or rule out uterine cancer. This test may be done in your doctor’s office, or you may be referred to another doctor. The doctor might perform more tests if the endometrial biopsy does not provide enough information, or if symptoms continue.

If one or more of these symptoms or risk factors is true for you,

it does not mean you have or will necessarily get uterine cancer.

 

Please report all your symptoms and risk factors to a doctor, preferably a gynecologist.
