Endometrial Cancer and Atypical Hyperplasia: When a Hysterectomy Is Recommended and What to Expect

Being told that a biopsy shows atypical hyperplasia or endometrial cancer is hard news, and a hysterectomy is often mentioned in the same conversation. Endometrial cancer starts in the lining of the uterus (the endometrium). It is the most common type of uterine cancer, and most cases are found after menopause.^[1][18] Atypical hyperplasia is not cancer, but it is a change in the lining that can already hide a cancer or turn into one, which is why surgery is usually advised.^[7][8] This guide explains what the words on your report mean, why a hysterectomy is the main treatment for both conditions, what type of operation is done and why, what the pathology report after surgery tells you, and what recovery and follow-up look like.

This guide explains general information about atypical hyperplasia, endometrial cancer and hysterectomy. It cannot account for your own test results, stage or health history, so please use it to prepare questions for your gynecologic oncologist or gynecologist, not to make decisions on your own.

What the words on your biopsy report mean

The endometrium is the lining that builds up and sheds each month before menopause. Estrogen makes it grow and progesterone keeps that growth in check. When the lining is exposed to estrogen without enough progesterone for a long time, it can thicken and its cells can change.^[4][8] Your report will usually use one of these terms:

• Endometrial hyperplasia without atypia: the lining is thicker than normal, but the cells look normal. It is not cancer. Fewer than 5 in 100 women with this type develop endometrial cancer over 20 years, and it often goes away by itself or with progesterone treatment.^[7][8]
• Atypical hyperplasia (also called endometrial intraepithelial neoplasia, EIN, or AEH): the cells themselves look abnormal. It is a precancer, and it carries a much higher risk, both of a cancer already being present and of cancer developing later.^[7][9]
• Endometrial carcinoma (endometrial cancer): cancer cells are present. The most common kind is called endometrioid. Some kinds, such as serous or clear cell carcinoma, behave more aggressively and are treated differently.^[11][12]

Uterine sarcoma, a rarer and different type of uterine cancer, is not covered here.^[1]

Who is more likely to have these changes

Endometrial cancer is most common after menopause; the average age at diagnosis in the United States is 60.^[1] Factors linked to a higher risk include excess body weight (fat tissue makes estrogen), estrogen-only hormone therapy in someone who still has a uterus, polycystic ovary syndrome (PCOS), taking tamoxifen, and inherited conditions such as Lynch syndrome.^[4][5] The American Cancer Society notes that the risk from tamoxifen is very low and that its benefits for breast cancer almost always outweigh it.^[4] Many women with these changes have none of these risk factors.

Symptoms and how the diagnosis is made

Abnormal vaginal bleeding is the most common symptom of endometrial cancer and hyperplasia.^[2][8] Signs to have checked include:^[2][3]

• any bleeding or spotting after menopause
• periods that are much heavier than usual for you, or bleeding between periods
• a change in vaginal discharge, even if it has no blood in it
• later on, pelvic pain, a feeling of fullness in the pelvis or weight loss without trying

These symptoms often have other, harmless causes, but they should always be checked.^[2][3] Our article on signs and reasons you might need a hysterectomy covers other causes of abnormal bleeding.

A diagnosis needs a sample of the lining looked at under a microscope. The usual first test is an endometrial biopsy, a quick office procedure in which a thin tube takes a small sample through the cervix. A transvaginal ultrasound can show whether the lining is thicker than expected. If the biopsy does not give enough tissue or the result is unclear, a hysteroscopy (a thin camera passed through the cervix) or a D&C (dilation and curettage) can take a larger sample.^[6] If cancer is found, imaging such as MRI, CT or a chest x-ray may be used to see whether it has spread.^[6]

Hyperplasia without atypia: usually not a hysterectomy first

For hyperplasia without atypia, guidelines from the Royal College of Obstetricians and Gynaecologists (RCOG) recommend progesterone treatment as the usual first step, and the hormonal IUD (levonorgestrel intrauterine system, such as Mirena) is the preferred form because it clears the condition more often than tablets. Treatment lasts at least six months, with repeat biopsies to check that the lining has returned to normal.^[7][8] Without treatment the condition goes away in about 7 to 8 out of 10 women; with progesterone, in about 9 out of 10.^[7] Our comparison of the Mirena IUD and hysterectomy explains how the hormonal IUD works.

A hysterectomy may be considered if the hyperplasia does not go away after 12 months of treatment, comes back, turns into atypical hyperplasia, or the bleeding continues, or if a woman cannot or does not want to have regular biopsies.^[7][8]

Atypical hyperplasia: why a hysterectomy is usually advised

Two facts explain why surgery is the usual recommendation for atypical hyperplasia once you no longer want to become pregnant:^[7][8][9]

• A cancer may already be there. A biopsy samples only part of the lining. The RCOG guideline cites research in which endometrial cancer was found in up to 43% of women who had a hysterectomy after a biopsy showing atypical hyperplasia. In that research, the cancers found were usually at an early stage.^[8]
• The risk of cancer later is substantial. RCOG patient information estimates that about 28 out of every 100 women with atypical hyperplasia would develop cancer within 20 years if it were not treated.^[7]

Because of this, the American College of Obstetricians and Gynecologists (ACOG) advises that doctors try to rule out a hidden cancer before surgery, for example with hysteroscopy and further sampling, and ACOG and RCOG both describe hysterectomy as the definitive treatment.^[8][9]

What kind of hysterectomy for atypical hyperplasia

Guidelines are fairly specific here, because the operation has to work well even if a cancer turns up in the final report:^[8][9]

• A total hysterectomy, which removes the uterus and the cervix.
• Not a supracervical (partial) hysterectomy, which leaves the cervix behind. Both RCOG and ACOG advise against it for atypical hyperplasia. Our guide to partial vs total hysterectomy explains the difference.
• Not endometrial ablation, because it cannot reliably destroy all of the lining and the scarring it leaves can make later biopsies difficult.^[8][9] See our comparison of endometrial ablation and hysterectomy.
• A laparoscopic (keyhole) approach is preferred over open surgery when possible, because it means a shorter hospital stay, less pain and a quicker recovery.^[8]
• No cutting of the uterus into pieces inside the body (morcellation), because of the risk of spreading cancer cells if a cancer is present. RCOG advises avoiding it; ACOG says that if it is ever needed it should be done inside a contained bag.^[8][9]
• No routine removal of lymph nodes, because most women do not have cancer, and in those who do, it is usually at an early stage.^[8]

The ovaries and tubes: after menopause, RCOG advises removing both ovaries and both tubes with the uterus (bilateral salpingo-oophorectomy). Before menopause, the decision about the ovaries should be made individually, but removing the fallopian tubes should be considered because it may lower the risk of a future ovarian cancer.^[8] Our guides to keeping or removing your ovaries and salpingectomy explain what each choice means.

If you want to become pregnant or cannot have surgery

Some women with atypical hyperplasia want to keep their fertility, and some are not well enough for surgery. In these cases, guidelines recommend progesterone treatment, with the hormonal IUD as the first choice and tablets as an alternative, together with regular biopsies (RCOG patient information mentions about every three months).^[7][8][9] Before starting, doctors should look carefully for a hidden cancer, including in the ovaries, and explain the risks of this approach. RCOG advises against trying for a pregnancy until a biopsy shows the hyperplasia has cleared, and a hysterectomy is usually recommended once you have finished having children, because the condition can come back.^[7][8]

When the report after surgery shows cancer

After any hysterectomy, the uterus is examined in the laboratory, and the full report comes back some days after the operation. If you had surgery for atypical hyperplasia and the report shows cancer, this is not unusual, and in most cases it is an early-stage cancer.^[8] Your doctor will explain the stage and grade and whether anything else is needed. For an early cancer, surgery alone is sometimes all the treatment needed; some women are offered further tests or more treatment.^[13] It is reasonable to ask for a copy of your pathology report and for someone to go through it with you.

Endometrial cancer: surgery is the main treatment

For almost everyone with endometrial cancer who is well enough for an operation, surgery is the first treatment. It usually means a total hysterectomy with removal of both tubes and ovaries, together with checks to see whether the cancer has spread (staging).^[10][13] For many women with early-stage cancer, surgery is the only treatment needed.^[13] It is reasonable to ask whether a gynecologic oncologist, a surgeon who specializes in cancers of the female reproductive organs, will do or plan your operation.

Type of hysterectomy

• Total hysterectomy (uterus and cervix) is the standard operation for uterine cancer.^[10]
• Radical hysterectomy also removes the upper vagina and the tissue around the cervix. It may be done if the cancer is thought to have spread to the cervix.^[10]
• A partial (supracervical) hysterectomy is not a standard option for endometrial cancer, because the cervix is removed as part of the treatment and staging.^[10]

How the operation is done

The American Cancer Society describes four approaches:^[10]

• Laparoscopic: through several small cuts using a camera. It usually causes less pain and blood loss. Our guide to laparoscopic hysterectomy explains the technique.
• Robotic-assisted laparoscopic: the surgeon controls the instruments through robotic arms; pain, blood loss and recovery are similar to standard laparoscopy.
• Abdominal (open): through a larger cut in the belly. It gives the surgeon a direct view, but recovery takes longer.
• Vaginal: rarely used for cancer, because it does not let the surgeon see the whole area, but it may be an option when health problems make other approaches too risky.

Lymph nodes, washings and other samples

Lymph nodes are small glands that can show whether cancer has started to spread. In early-stage cancer, many surgeons use sentinel lymph node mapping: a blue or green dye is injected into the cervix, and the first few nodes it reaches are removed and tested. If they are clear, no more nodes are taken. If imaging shows enlarged nodes, more nodes in the pelvis and along the aorta may be removed.^[10] The surgeon may also rinse the pelvis and abdomen with salt water and send the fluid to the lab (peritoneal washings), and, for more aggressive types of cancer, take a sample of the omentum, a fatty layer that covers the abdominal organs.^[10]

Can younger women keep their ovaries?

Removing the ovaries before menopause causes menopause straight away. For some premenopausal women with an early-stage, non-aggressive cancer, keeping the ovaries may be considered after a discussion with the surgeon. According to the American Cancer Society, keeping them may increase the chance that the cancer comes back, but it does not seem to increase the risk of dying from endometrial cancer.^[10][13] Our article on surgical menopause explains what happens when the ovaries are removed before menopause.

If surgery is not possible or you want to keep your fertility

Women who cannot have surgery because of other health problems are often treated with radiation instead.^[13] For a small group of younger women with a very early, low-grade endometrioid cancer who want to have children, surgery may be postponed while the cancer is treated with progestin, with a biopsy or D&C every 3 to 6 months. The American Cancer Society stresses that this is not standard treatment and may increase the risk of the cancer growing or spreading, recommends a second opinion from a gynecologic oncologist and a pathologist, and advises a hysterectomy once childbearing is complete.^[13]

Understanding stage, grade and tumor tests

Endometrial cancer can be diagnosed, staged and treated in the same operation.^[12] Its stage is usually set from what is found during surgery and in the lab afterwards (surgical staging), so your final stage may not be known until the lab results come back after the operation.^[11] In simple terms:^[12]

Stage	What it means in plain words
Stage I	The cancer is only in the uterus. In stage IA it is in the lining or less than halfway into the muscle wall; in stage IB it is halfway or more into the muscle.
Stage II	The cancer has spread into the connective tissue of the cervix but not outside the uterus.
Stage III	The cancer has spread beyond the uterus and cervix but stays in the pelvis, for example to the tubes, ovaries, vagina or nearby lymph nodes.
Stage IV	The cancer has spread to the bladder or bowel wall, or to more distant parts of the body.

The international FIGO staging system was updated in 2023 to take into account that some types of endometrial cancer are more aggressive than others, so you may see sub-stages on your report that differ from older descriptions.^[11][17] Your report will also give a grade: grades 1 and 2 grow more slowly, and grade 3 tumors, which include serous, clear cell and carcinosarcoma types, are considered higher risk.^[12]

The tumor is often tested further. One common test looks for mismatch repair (MMR) proteins or microsatellite instability (MSI). Abnormal results can mean the cancer may respond to immunotherapy, and they can also be a sign of Lynch syndrome, an inherited condition, in which case your doctor may recommend genetic testing.^[6] Other molecular tests (such as POLE and p53) help predict how the cancer is likely to behave.^[17] If Lynch syndrome is found, it matters for your relatives too, so it is worth asking whether you should see a genetic counselor.

Treatment after surgery

Whether you need more treatment depends on the stage, grade, type and test results. Very broadly, many women with stage I cancer need no further treatment, while for higher-risk stage I and for stage II, radiation is often recommended, usually as internal radiation to the top of the vagina (vaginal brachytherapy) and sometimes pelvic radiation. For stage III and IV, chemotherapy, radiation or both are used, and hormone therapy, targeted therapy and immunotherapy are options for advanced or recurrent cancer.^[13][16] Your oncology team will explain why they recommend a particular plan for you.

What the survival numbers mean, and what they do not

The National Cancer Institute notes that endometrial cancer can usually be cured because it is usually diagnosed early.^[19] The American Cancer Society publishes five-year relative survival rates, which compare people with the cancer to people in the general population. For women diagnosed in the United States between 2015 and 2021, they were:^[14]

Extent at diagnosis	5-year relative survival
Localized (only in the uterus)	96%
Regional (spread to nearby tissue or lymph nodes)	72%
Distant (spread to far parts of the body)	22%
All stages combined	84%

These figures need careful reading. They are averages from women treated at least five years ago, they do not take into account the type and grade of cancer, your age or your general health, and they only describe the stage when the cancer was first found. Treatment keeps improving, so women diagnosed now may do better.^[14] They cannot tell you what will happen to you; your oncologist is the best person to explain what they mean in your situation.

Recovery and life after surgery

After a laparoscopic or robotic hysterectomy, most women go home the same day or the next, and full recovery takes about 3 to 4 weeks. After open surgery, the hospital stay is usually 2 to 7 days and recovery takes about 4 to 6 weeks.^[10] Possible complications include bleeding, infection, blood clots and injury to the bladder or bowel; after a radical hysterectomy, a urinary catheter may be needed for days or up to two weeks.^[10] Our guide to recovery week by week covers the first weeks in detail.

• Menopause: if your ovaries were removed before menopause, menopause starts straight away, with symptoms such as hot flashes, and a longer-term effect on bone and heart health.^[10] Whether hormone therapy is safe after endometrial cancer depends on the type and stage, so ask your oncologist before starting it; do not assume either way. Our article on HRT after hysterectomy explains the general evidence.
• Lymphedema: if many lymph nodes were removed, especially if you also have radiation, there is a risk of long-lasting swelling in the legs or genital area. Tell your team early if you notice swelling.^[10]
• Sex and body image: treatment can affect sexual health; it is a normal and important topic to raise with your team.^[10]
• Emotions: a cancer diagnosis on top of surgery is a lot to absorb. Our guide to emotional recovery after hysterectomy has practical ideas and places to find support.

Follow-up after endometrial cancer

After treatment for cancer, you will usually have check-ups every 3 to 6 months for the first 2 to 3 years, then every 6 to 12 months until five years, and then once a year. If you feel well and the examination is normal, routine scans and blood tests are generally not needed, and a routine Pap test of the vagina is no longer recommended as part of follow-up.^[15] Contact your team without waiting for your next appointment if you notice:^[15]

• bleeding from the vagina, bladder or rectum
• pain in the pelvis, hips, belly or back
• swelling in the belly or legs
• a cough or shortness of breath that does not go away
• loss of appetite or weight loss without trying

Call 911 or go to the emergency room for heavy bleeding, sudden chest pain or breathlessness, or a painful, swollen leg after surgery.

Questions to ask your doctor

• Does my biopsy show hyperplasia without atypia, atypical hyperplasia or cancer? Can I have a copy of the report?
• Do I need more tests, such as a hysteroscopy or imaging, before surgery?
• Will a gynecologic oncologist do or be involved in my operation?
• Which organs will you remove: the uterus and cervix, the tubes, the ovaries, any lymph nodes?
• Can it be done by laparoscopy or robotic surgery, and how will the uterus be removed?
• If I keep my ovaries, what does that mean for my risk?
• When will the final pathology report be ready, and who will explain it to me?
• Will my tumor be tested for MMR or Lynch syndrome, and should my family know the result?
• Will I need radiation or other treatment after surgery?
• Is hormone therapy safe for me if I have menopause symptoms?
• What follow-up will I have, and which symptoms should make me call?
