Endometrial Cancer Treatment (PDQ®)–Patient Version

General Information About Endometrial Cancer

Key Points

  • Endometrial cancer is a disease in which malignant (cancer) cells form in the tissues of the endometrium.
  • Obesity and having metabolic syndrome may increase the risk of endometrial cancer.
  • Taking tamoxifen for breast cancer or taking estrogen alone (without progesterone) can increase the risk of endometrial cancer.
  • Signs and symptoms of endometrial cancer include unusual vaginal bleeding or pain in the pelvis.
  • Tests that examine the endometrium are used to diagnose endometrial cancer.
  • Certain factors affect prognosis (chance of recovery) and treatment options.

Endometrial cancer is a disease in which malignant (cancer) cells form in the tissues of the endometrium.

The endometrium is the lining of the uterus, a hollow, muscular organ in a woman’s pelvis. The uterus is where a fetus grows. In most nonpregnant women, the uterus is about 3 inches long. The lower, narrow end of the uterus is the cervix, which leads to the vagina.

Anatomy of the female reproductive system. The organs in the female reproductive system include the uterus, ovaries, fallopian tubes, cervix, and vagina. The uterus has a muscular outer layer called the myometrium and an inner lining called the endometrium.

Cancer of the endometrium is different from cancer of the muscle of the uterus, which is called sarcoma of the uterus. See the PDQ summary on Uterine Sarcoma Treatment for more information about uterine sarcoma.

Obesity and having metabolic syndrome may increase the risk of endometrial cancer.

Anything that increases your chance of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesn't mean that you will not get cancer. Talk to your doctor if you think you may be at risk for endometrial cancer.

Risk factors for endometrial cancer include the following:

Older age is the main risk factor for most cancers. The chance of getting cancer increases as you get older.

Taking tamoxifen for breast cancer or taking estrogen alone (without progesterone) can increase the risk of endometrial cancer.

Endometrial cancer may develop in breast cancer patients who have been treated with tamoxifen. A patient who takes this drug and has abnormal vaginal bleeding should have a follow-up exam and a biopsy of the endometrial lining if needed. Women taking estrogen (a hormone that can affect the growth of some cancers) alone also have an increased risk of endometrial cancer. Taking estrogen combined with progesterone (another hormone) does not increase a woman’s risk of endometrial cancer.

Signs and symptoms of endometrial cancer include unusual vaginal bleeding or pain in the pelvis.

These and other signs and symptoms may be caused by endometrial cancer or by other conditions. Check with your doctor if you have any of the following:

  • Vaginal bleeding or discharge not related to menstruation (periods).
  • Vaginal bleeding after menopause.
  • Difficult or painful urination.
  • Pain during sexual intercourse.
  • Pain in the pelvic area.

Tests that examine the endometrium are used to diagnose endometrial cancer.

Because endometrial cancer begins inside the uterus, it does not usually show up in the results of a Pap test. For this reason, a sample of endometrial tissue must be removed and checked under a microscope to look for cancer cells. One of the following procedures may be used:

  • Endometrial biopsy: The removal of tissue from the endometrium (inner lining of the uterus) by inserting a thin, flexible tube through the cervix and into the uterus. The tube is used to gently scrape a small amount of tissue from the endometrium and then remove the tissue samples. A pathologist views the tissue under a microscope to look for cancer cells.
  • Dilatation and curettage: A procedure to remove samples of tissue from the inner lining of the uterus. The cervix is dilated and a curette (spoon-shaped instrument) is inserted into the uterus to remove tissue. The tissue samples are checked under a microscope for signs of disease. This procedure is also called a D&C.

  • Hysteroscopy: A procedure to look inside the uterus for abnormal areas. A hysteroscope is inserted through the vagina and cervix into the uterus. A hysteroscope is a thin, tube-like instrument with a light and a lens for viewing. It may also have a tool to remove tissue samples, which are checked under a microscope for signs of cancer.

Other tests and procedures used to diagnose endometrial cancer include the following:

  • Physical exam and health history: An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patient’s health habits and past illnesses and treatments will also be taken.
  • Transvaginal ultrasound exam: A procedure used to examine the vagina, uterus, fallopian tubes, and bladder. An ultrasound transducer (probe) is inserted into the vagina and used to bounce high-energy sound waves (ultrasound) off internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram. The doctor can identify tumors by looking at the sonogram.

Certain factors affect prognosis (chance of recovery) and treatment options.

The prognosis and treatment options depend on the following:

  • The stage of the cancer (whether it is in the endometrium only, involves the uterus wall, or has spread to other places in the body).
  • How the cancer cells look under a microscope.
  • Whether the cancer cells are affected by progesterone.

Endometrial cancer can usually be cured because it is usually diagnosed early.

Stages of Endometrial Cancer

Key Points

  • After endometrial cancer has been diagnosed, tests are done to find out if cancer cells have spread within the uterus or to other parts of the body.
  • There are three ways that cancer spreads in the body.
  • Cancer may spread from where it began to other parts of the body.
  • The following stages are used for endometrial cancer:
    • Stage I
    • Stage II
    • Stage III
    • Stage IV
  • Endometrial cancer may be grouped for treatment as follows:
    • Low-risk endometrial cancer
    • High-risk endometrial cancer
  • Endometrial cancer can recur (come back) after it has been treated.

After endometrial cancer has been diagnosed, tests are done to find out if cancer cells have spread within the uterus or to other parts of the body.

The process used to find out whether the cancer has spread within the uterus or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage in order to plan treatment. Certain tests and procedures are used in the staging process. A hysterectomy (an operation in which the uterus is removed) will usually be done to treat endometrial cancer. Tissue samples are taken from the area around the uterus and checked under a microscope for signs of cancer to help find out whether the cancer has spread.

The following procedures may be used in the staging process:

  • Pelvic exam: An exam of the vagina, cervix, uterus, fallopian tubes, ovaries, and rectum. A speculum is inserted into the vagina and the doctor or nurse looks at the vagina and cervix for signs of disease. A Pap test of the cervix is usually done. The doctor or nurse also inserts one or two lubricated, gloved fingers of one hand into the vagina and places the other hand over the lower abdomen to feel the size, shape, and position of the uterus and ovaries. The doctor or nurse also inserts a lubricated, gloved finger into the rectum to feel for lumps or abnormal areas.

The inset shows a woman covered by a drape on an exam table with her legs apart and her feet in stirrups.

This is done to feel the size, shape, and position of the uterus and ovaries. The vagina, cervix, fallopian tubes, and rectum are also checked.
  • Chest x-ray: An x-ray of the organs and bones inside the chest. An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body.
  • CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography.
  • MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI).
  • PET scan (positron emission tomography scan): A procedure to find malignant tumor cells in the body. A small amount of radioactive glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do.
  • Lymph node dissection: A surgical procedure in which the lymph nodes are removed from the pelvic area and a sample of tissue is checked under a microscope for signs of cancer. This procedure is also called lymphadenectomy.

There are three ways that cancer spreads in the body.

Cancer can spread through tissue, the lymph system, and the blood:

  • Tissue. The cancer spreads from where it began by growing into nearby areas.
  • Lymph system. The cancer spreads from where it began by getting into the lymph system. The cancer travels through the lymph vessels to other parts of the body.
  • Blood. The cancer spreads from where it began by getting into the blood. The cancer travels through the blood vessels to other parts of the body.

Cancer may spread from where it began to other parts of the body.

When cancer spreads to another part of the body, it is called metastasis. Cancer cells break away from where they began (the primary tumor) and travel through the lymph system or blood.

  • Lymph system. The cancer gets into the lymph system, travels through the lymph vessels, and forms a tumor (metastatic tumor) in another part of the body.
  • Blood. The cancer gets into the blood, travels through the blood vessels, and forms a tumor (metastatic tumor) in another part of the body.

The metastatic tumor is the same type of cancer as the primary tumor. For example, if endometrial cancer spreads to the lung, the cancer cells in the lung are actually endometrial cancer cells. The disease is metastatic endometrial cancer, not lung cancer.

Many cancer deaths are caused when cancer moves from the original tumor and spreads to other tissues and organs. This is called metastatic cancer. This animation shows how cancer cells travel from the place in the body where they first formed to other parts of the body.

The following stages are used for endometrial cancer:

Stage I

EnlargeStage IA and stage IB endometrial cancer shown in two cross-section drawings of the uterus and cervix. Drawing on the left shows stage IA, with cancer in the endometrium and myometrium of the uterus. Drawing on the right shows stage IB, with cancer more than halfway through the myometrium. Also shown are the fallopian tubes, ovaries, and vagina.
Stage IA and stage IB endometrial cancer. In stage IA, cancer is in the endometrium only or less than halfway through the myometrium (the muscle layer of the uterus). In stage IB, cancer has spread halfway or more into the myometrium.

In stage I, cancer is found in the uterus only. Stage I is divided into stages IA and IB, based on how far the cancer has spread.

Stage II

EnlargeStage II endometrial cancer shown in a cross-section drawing of the uterus, cervix, fallopian tubes, ovaries, and vagina. Cancer is shown in the endometrium and myometrium of the uterus and in the cervix.
Stage II endometrial cancer. Cancer has spread into connective tissue of the cervix, but has not spread outside the uterus.

In stage II, cancer has spread into connective tissue of the cervix, but has not spread outside the uterus.

Stage III

In stage III, cancer has spread beyond the uterus and cervix, but has not spread beyond the pelvis. Stage III is divided into stages IIIA, IIIB, and IIIC, based on how far the cancer has spread within the pelvis.

  • Stage IIIA: Cancer has spread to the outer layer of the uterus and/or to the fallopian tubes, ovaries, and ligaments of the uterus.
    EnlargeStage IIIA endometrial cancer shown in a cross-section drawing of the uterus, ligaments of the uterus, cervix, fallopian tubes, ovaries, and vagina. Cancer is shown in the endometrium of the uterus, the outer layer of the uterus, a fallopian tube, an ovary, and a ligament of the uterus.
    Stage IIIA endometrial cancer. Cancer has spread to the outer layer of the uterus and/or to the fallopian tubes, ovaries, or ligaments of the uterus.
  • Stage IIIB: Cancer has spread to the vagina and/or to the parametrium (connective tissue and fat around the uterus).
    EnlargeStage IIIB endometrial cancer shown in a cross-section drawing of the uterus, cervix, fallopian tubes, ovaries, and vagina. Cancer is shown in the endometrium of the uterus, the parametrium, the cervix, and the vagina.
    Stage IIIB endometrial cancer. Cancer has spread to the vagina and/or to the parametrium (connective tissue and fat around the uterus and cervix).
  • Stage IIIC: Cancer has spread to lymph nodes in the pelvis and/or around the aorta (largest artery in the body, which carries blood away from the heart).
    EnlargeStage IIIC endometrial cancer; drawing shows cancer in the endometrium and myometrium of the uterus. Also shown is cancer in lymph nodes in the pelvis and near the aorta.
    Stage IIIC endometrial cancer. Cancer has spread to lymph nodes in the pelvis and/or around the aorta (the largest artery in the body that carries blood away from the heart).

Stage IV

In stage IV, cancer has spread beyond the pelvis. Stage IV is divided into stages IVA and IVB, based on how far the cancer has spread.

  • Stage IVA: Cancer has spread to the bladder and/or bowel wall.
    EnlargeStage IVA endometrial cancer shown in a side-view cross-section drawing of the uterus, bladder, cervix, vagina, small intestine, and large intestine. Cancer is shown in the bladder, uterus, and bowel.
    Stage IVA endometrial cancer. Cancer has spread into the bladder and/or bowel.
  • Stage IVB: Cancer has spread to other parts of the body beyond the pelvis, including the abdomen and/or lymph nodes in the groin.
    EnlargeStage IVB endometrial cancer; drawing shows cancer that has spread to parts of the body outside the pelvis, including the abdomen and lymph nodes in the groin. An inset shows cancer cells spreading from the endometrium, through the blood and lymph system, to another part of the body where metastatic cancer has formed.
    Stage IVB endometrial cancer. The cancer has spread to parts of the body outside the pelvis, including the abdomen and/or lymph nodes in the groin.

Endometrial cancer may be grouped for treatment as follows:

Low-risk endometrial cancer

Grades 1 and 2 tumors are usually considered low-risk. They usually do not spread to other parts of the body.

High-risk endometrial cancer

Grade 3 tumors are considered high-risk. They often spread to other parts of the body. Uterine papillary serous, clear cell, and carcinosarcoma are three subtypes of endometrial cancer that are considered grade 3.

Endometrial cancer can recur (come back) after it has been treated.

The cancer may come back in the uterus, the pelvis, in lymph nodes in the abdomen, or in other parts of the body.

Treatment Option Overview

Key Points

  • There are different types of treatment for patients with endometrial cancer.
  • Five types of standard treatment are used:
    • Surgery
    • Radiation therapy
    • Chemotherapy
    • Hormone therapy
    • Targeted therapy
  • New types of treatment are being tested in clinical trials.
  • Treatment for endometrial cancer may cause side effects.
  • Patients may want to think about taking part in a clinical trial.
  • Patients can enter clinical trials before, during, or after starting their cancer treatment.
  • Follow-up tests may be needed.

There are different types of treatment for patients with endometrial cancer.

Different types of treatment are available for patients with endometrial cancer. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.

Five types of standard treatment are used:

Surgery

Surgery (removing the cancer in an operation) is the most common treatment for endometrial cancer. The following surgical procedures may be used:

  • Total hysterectomy: Surgery to remove the uterus, including the cervix. If the uterus and cervix are taken out through the vagina, the operation is called a vaginal hysterectomy. If the uterus and cervix are taken out through a large incision (cut) in the abdomen, the operation is called a total abdominal hysterectomy. If the uterus and cervix are taken out through a small incision (cut) in the abdomen using a laparoscope, the operation is called a total laparoscopic hysterectomy.
    EnlargeHysterectomy; drawing shows the female reproductive anatomy, including the ovaries, uterus, vagina, fallopian tubes, and cervix. Dotted lines show which organs and tissues are removed in a total hysterectomy, a total hysterectomy with salpingo-oophorectomy, and a radical hysterectomy. An inset shows the location of two possible incisions on the abdomen: a low transverse incision is just above the pubic area and a vertical incision is between the navel and the pubic area.
    Hysterectomy. The uterus is surgically removed with or without other organs or tissues. In a total hysterectomy, the uterus and cervix are removed. In a total hysterectomy with salpingo-oophorectomy, (a) the uterus plus one (unilateral) ovary and fallopian tube are removed; or (b) the uterus plus both (bilateral) ovaries and fallopian tubes are removed. In a radical hysterectomy, the uterus, cervix, both ovaries, both fallopian tubes, and nearby tissue are removed. These procedures are done using a low transverse incision or a vertical incision.
  • Bilateral salpingo-oophorectomy: Surgery to remove both ovaries and both fallopian tubes.
  • Radical hysterectomy: Surgery to remove the uterus, cervix, and part of the vagina. The ovaries, fallopian tubes, or nearby lymph nodes may also be removed.
  • Lymph node dissection: A surgical procedure in which the lymph nodes are removed from the pelvic area and a sample of tissue is checked under a microscope for signs of cancer. This procedure is also called lymphadenectomy.

After the doctor removes all the cancer that can be seen at the time of the surgery, some patients may be given radiation therapy or hormone treatment after surgery to kill any cancer cells that are left. Treatment given after the surgery, to lower the risk that the cancer will come back, is called adjuvant therapy.

Radiation therapy

Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy:

The way the radiation therapy is given depends on the type and stage of the cancer being treated. External and internal radiation therapy are used to treat endometrial cancer, and may also be used as palliative therapy to relieve symptoms and improve quality of life.

Chemotherapy

Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping the cells from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the cerebrospinal fluid, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy).

The way the chemotherapy is given depends on the type and stage of the cancer being treated.

Hormone therapy

Hormone therapy is a cancer treatment that removes hormones or blocks their action and stops cancer cells from growing. Hormones are substances made by glands in the body and circulated in the bloodstream. Some hormones can cause certain cancers to grow. If tests show that the cancer cells have places where hormones can attach (receptors), drugs, surgery, or radiation therapy is used to reduce the production of hormones or block them from working.

Targeted therapy

Targeted therapy is a type of treatment that uses drugs or other substances to identify and attack specific cancer cells. Targeted therapies usually cause less harm to normal cells than chemotherapy or radiation therapy do. Monoclonal antibodies, mTOR inhibitors, and signal transduction inhibitors are three types of targeted therapy used to treat endometrial cancer.

  • Monoclonal antibody therapy: Monoclonal antibodies are immune system proteins made in the laboratory to treat many diseases, including cancer. As a cancer treatment, these antibodies can attach to a specific target on cancer cells or other cells that may help cancer cells grow. The antibodies are able to then kill the cancer cells, block their growth, or keep them from spreading. Monoclonal antibodies are given by infusion. They may be used alone or to carry drugs, toxins, or radioactive material directly to cancer cells. Bevacizumab is used to treat stage III, stage IV, and recurrent endometrial cancer.
    How do monoclonal antibodies work to treat cancer? This video shows how monoclonal antibodies, such as trastuzumab, pembrolizumab, and rituximab, block molecules cancer cells need to grow, flag cancer cells for destruction by the body’s immune system, or deliver harmful substances to cancer cells.
  • mTOR inhibitor therapy: mTOR inhibitors block a protein called mTOR, which helps control cell division. mTOR inhibitors may keep cancer cells from growing and prevent the growth of new blood vessels that tumors need to grow. Everolimus and ridaforolimus are used to treat stage III, stage IV, and recurrent endometrial cancer.
  • Signal transduction inhibitor therapy: Signal transduction inhibitors block signals that are passed from one molecule to another inside a cell. Blocking these signals may kill cancer cells. Metformin is being studied to treat stage III, stage IV, and recurrent endometrial cancer.

New types of treatment are being tested in clinical trials.

Information about clinical trials is available from the NCI website.

Treatment for endometrial cancer may cause side effects.

For information about side effects caused by treatment for cancer, see our Side Effects page.

Patients may want to think about taking part in a clinical trial.

For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.

Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment.

Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward.

Patients can enter clinical trials before, during, or after starting their cancer treatment.

Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment.

Clinical trials are taking place in many parts of the country. Information about clinical trials supported by NCI can be found on NCI’s clinical trials search webpage. Clinical trials supported by other organizations can be found on the ClinicalTrials.gov website.

Follow-up tests may be needed.

Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests.

Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups.

About This PDQ Summary

About PDQ

Physician Data Query (PDQ) is the National Cancer Institute's (NCI's) comprehensive cancer information database. The PDQ database contains summaries of the latest published information on cancer prevention, detection, genetics, treatment, supportive care, and complementary and alternative medicine. Most summaries come in two versions. The health professional versions have detailed information written in technical language. The patient versions are written in easy-to-understand, nontechnical language. Both versions have cancer information that is accurate and up to date and most versions are also available in Spanish.

PDQ is a service of the NCI. The NCI is part of the National Institutes of Health (NIH). NIH is the federal government’s center of biomedical research. The PDQ summaries are based on an independent review of the medical literature. They are not policy statements of the NCI or the NIH.

Purpose of This Summary

This PDQ cancer information summary has current information about the treatment of endometrial cancer. It is meant to inform and help patients, families, and caregivers. It does not give formal guidelines or recommendations for making decisions about health care.

Reviewers and Updates

Editorial Boards write the PDQ cancer information summaries and keep them up to date. These Boards are made up of experts in cancer treatment and other specialties related to cancer. The summaries are reviewed regularly and changes are made when there is new information. The date on each summary ("Updated") is the date of the most recent change.

The information in this patient summary was taken from the health professional version, which is reviewed regularly and updated as needed, by the PDQ Adult Treatment Editorial Board.

Clinical Trial Information

A clinical trial is a study to answer a scientific question, such as whether one treatment is better than another. Trials are based on past studies and what has been learned in the laboratory. Each trial answers certain scientific questions in order to find new and better ways to help cancer patients. During treatment clinical trials, information is collected about the effects of a new treatment and how well it works. If a clinical trial shows that a new treatment is better than one currently being used, the new treatment may become "standard." Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.

Clinical trials can be found online at NCI's website. For more information, call the Cancer Information Service (CIS), NCI's contact center, at 1-800-4-CANCER (1-800-422-6237).
