Being told that you have an endometrial polyp after menopause can feel worrying. You may immediately wonder whether the growth is cancerous, why it has developed after your periods have stopped and whether it needs to be removed.
Most endometrial polyps are benign, including those found after menopause. However, postmenopausal status and vaginal bleeding are associated with a greater likelihood of abnormal cells than in younger people without symptoms, so your gynaecologist will usually recommend careful investigation.
Any vaginal bleeding after menopause should be medically assessed, even if it happens only once or involves a small amount of spotting. A polyp may be responsible, but investigation is needed to exclude changes such as endometrial hyperplasia or cancer.
What Is an Endometrial Polyp?
An endometrial polyp is a growth that develops from the tissue lining the inside of your womb, known as the endometrium. It may be attached by a thin stalk or have a broader base, and its size can range from very small to large enough to affect the womb cavity.
You may have one polyp or several, and they may be found during investigations for bleeding or discovered unexpectedly during a scan. Endometrial polyps are different from fibroids, as polyps develop from the womb lining while fibroids develop from muscle and fibrous tissue. Most polyps are non-cancerous, but removed tissue is usually sent to a laboratory for examination to confirm its nature.
What Does “After the Menopause” Mean?
Menopause is usually confirmed when you have not had a menstrual period for 12 consecutive months and there is no other reason for your periods to have stopped. The time after this point is known as postmenopause.
After menopause, your ovaries produce much lower levels of oestrogen and progesterone, causing the womb lining to become thin. This means you should not normally experience vaginal bleeding, so any new bleeding, spotting or blood-stained discharge is considered postmenopausal bleeding and should be assessed.
Why Can Endometrial Polyps Develop After Menopause?
The exact reason why endometrial polyps develop is not always clear. Polyps are thought to form when a small area of the womb lining grows differently from the surrounding tissue.
Although hormone levels are lower after menopause, the womb lining can still respond to oestrogen from other sources or hormone treatments. Some polyps may have developed during perimenopause and only be discovered later when they cause bleeding after a long period without periods. Developing a polyp is not your fault and is not linked to poor hygiene or anything you have done.
What Symptoms Can a Postmenopausal Polyp Cause?
Postmenopausal bleeding is the symptom most commonly linked with an endometrial polyp after menopause. You may notice light spotting, blood on toilet tissue, bleeding in your underwear or watery pink or brown discharge, even if it happens only once.
Many polyps do not cause any symptoms and may be found during an ultrasound scan carried out for another reason. Pelvic pain is not usually the main symptom, but a larger polyp may occasionally cause cramping or discomfort if it affects the womb cavity or extends towards the cervix.
Why Must Postmenopausal Bleeding Be Investigated?
Most people with postmenopausal bleeding do not have cancer. Common causes include thinning of the vaginal or womb tissues, endometrial polyps and bleeding linked with hormone replacement therapy.
However, bleeding after menopause can sometimes be an early sign of conditions affecting the womb lining, cervix or vagina, so it should always be assessed. Your doctor will consider factors such as your age, scan findings, medical history and laboratory results to understand the possible cause. Being referred for investigation does not mean you have cancer; it helps ensure that important causes are identified or ruled out promptly.
UK Guidance:
NHS advice is that any vaginal bleeding after menopause should be checked by a GP, even if it happens only once or involves a small amount of spotting or pink or brown discharge. Under current NICE guidance, women aged 55 and over with unexplained postmenopausal bleeding that cannot be attributed to HRT should be referred through a suspected cancer pathway. Referral should also be considered for women under 55. Unscheduled bleeding while taking HRT should be assessed according to the bleeding pattern, HRT regimen and current UK guidance.
Are Endometrial Polyps After Menopause Cancerous?
Most endometrial polyps are benign, including those found after menopause. However, the likelihood of precancerous or cancerous changes is higher after menopause, particularly when a polyp is associated with bleeding, although most endometrial polyps remain benign. This is why removed polyps are usually sent to a laboratory for detailed examination.
Research suggests that factors such as your age, symptoms, menopausal status and bleeding pattern influence the level of concern. A postmenopausal polyp does not mean you have cancer, but laboratory testing helps confirm the diagnosis and ensures any concerning changes are identified.
| Finding | What it generally means |
| Benign endometrial polyp | Non-cancerous tissue with no atypical cells |
| Hyperplasia without atypia | Overgrowth of the womb lining without markedly abnormal cells |
| Atypical hyperplasia/endometrial intraepithelial neoplasia (EIN) | Abnormal precancerous changes with a greater risk of existing or future cancer |
| Endometrial cancer | Malignant cells arising from the womb lining |
| Inadequate sample | Too little tissue to provide a reliable diagnosis, meaning further assessment may be needed |
Research Insight:
A systematic review and meta-analysis involving 35,345 women found that most endometrial polyps were benign. Malignant polyps were identified more often in postmenopausal women than in premenopausal women and more often in women with bleeding than in those without symptoms. These figures cannot predict your individual result. The review included women whose polyps were removed and examined, so its findings may not represent the risk associated with every incidentally detected polyp. However, they help explain why postmenopausal bleeding and menopausal status influence decisions about removal and histological examination.
Which Factors Can Increase Concern About Abnormal Cells?
Certain factors may increase the need for closer assessment of an endometrial polyp after menopause. These include your age, menopausal status, abnormal bleeding, a thicker womb lining on ultrasound and other health factors that may affect your risk.
Conditions such as obesity, diabetes, prolonged exposure to oestrogen without enough progesterone and Lynch syndrome can also be relevant when assessing the womb lining. Having these risk factors does not mean your polyp is cancerous, but your gynaecologist may use this information to decide whether the polyp or surrounding tissue needs further examination.
What If the Polyp Was Found Without Any Bleeding?
An asymptomatic polyp is one found during a scan when you have not experienced postmenopausal bleeding or blood-stained discharge. These polyps often have a lower risk of abnormal changes, but your gynaecologist will consider factors such as the size, appearance, your age and the thickness of your womb lining before recommending the next step.
Not every incidental polyp automatically requires immediate surgery. However, an endometrial polyp found after menopause should receive specialist risk assessment. Monitoring may be considered for selected women after shared decision-making, particularly when the polyp appears low risk and the potential disadvantages of removal outweigh the likely benefits. Your symptoms, polyp size and appearance, womb-lining thickness, medical history, general health and preferences will all influence the recommendation.
Can HRT Cause Bleeding or Endometrial Polyps?
Hormone replacement therapy (HRT) can cause unexpected bleeding, especially during the first few months after starting treatment or after a change in your dose or type of HRT. However, bleeding should not automatically be assumed to be caused by HRT, as the timing and pattern of symptoms also need to be assessed.
Your doctor may recommend an ultrasound, hysteroscopy or biopsy depending on your symptoms, scan findings and HRT regimen. Do not stop prescribed HRT without speaking to a healthcare professional, and bring details of your medication to your appointment so your gynaecologist can advise you appropriately.
What If You Take Tamoxifen?
Tamoxifen is used to treat and reduce the risk of some hormone-sensitive breast cancers. While it blocks oestrogen effects in breast tissue, it can have an oestrogen-like effect on the womb lining, which may contribute to changes such as thickening or polyps.
If you experience abnormal bleeding while taking tamoxifen, it should be assessed by a healthcare professional. Do not stop tamoxifen on your own because of bleeding or a polyp; speak with your breast cancer and gynaecology teams so they can advise you safely.
What Happens at Your First Assessment?
Your appointment will usually begin with a discussion about your bleeding, including when it started, how often it occurs and whether you have other symptoms such as pain or unusual discharge. Your clinician may also ask about your menopause history, HRT, tamoxifen, previous pregnancies and any relevant family or medical history.
You may be offered an examination and a transvaginal ultrasound to help identify the possible cause of the bleeding. If further assessment is needed, your gynaecologist may recommend hysteroscopy or a biopsy of the womb lining. You should be given an explanation before any examination and can ask questions or request that it stops at any time.
Clinical Tip:
Even if your bleeding has stopped before your appointment, it is still important to attend your assessment. Temporary improvement does not necessarily identify the underlying cause.
What Does a Transvaginal Ultrasound Show?
A transvaginal ultrasound uses a slim probe placed gently inside your vagina to provide a detailed view of your womb lining, ovaries and other pelvic structures. It can help your doctor assess the thickness of your endometrium and look for changes such as polyps, fibroids or fluid inside the womb cavity.
An ultrasound can suggest the presence of a polyp, but it cannot confirm whether the tissue is benign. If further assessment is needed, hysteroscopy allows your gynaecologist to look directly inside your womb and take a biopsy or remove the polyp. You can ask for the scan to pause or stop if you feel uncomfortable.
What Happens During the Hysteroscopy?
During a hysteroscopy, you will usually change from the waist down and be positioned comfortably while the clinical team explains each step. A thin hysteroscope is gently passed through your vagina and cervix, allowing the clinician to view the inside of your womb on a monitor.
- Using Sterile Fluid: Saline is used to open the womb cavity and improve visibility, so you may notice some fluid leakage afterwards.
- Identifying the Polyp: The clinician locates the polyp, checks how it is attached and examines the rest of the womb lining.
- Deciding Next Steps: Once the polyp is assessed, your clinician determines the most appropriate treatment approach.
- Comfort and Explanation: The team will explain what is happening throughout the procedure to help you feel at ease.
Depending on your findings, your clinician may take a biopsy, remove the polyp or recommend further assessment based on the appearance of the womb lining.
How Is a Postmenopausal Polyp Removed?
Endometrial polyps are usually removed using hysteroscopy, where a small instrument is passed through or alongside the hysteroscope to separate the polyp from your womb lining. The method used depends on the size, location and attachment of the polyp.
Removing a polyp under direct vision allows your clinician to target the growth and examine the surrounding womb lining. Small polyps may be removed during an outpatient appointment, while larger or more complex polyps may require treatment in a theatre setting with an anaesthetic.
Why Is the Polyp Sent for Histology?
Histology involves examining the removed polyp tissue under a microscope to check the cells and confirm whether it is benign or contains any abnormal changes. This assessment is more reliable than judging the appearance of a polyp during hysteroscopy alone.
Your doctor may also recommend sampling the surrounding womb lining, as changes can sometimes occur outside the visible polyp. Results are not usually available immediately, and your clinic should explain when and how you will receive them. If you do not hear back within the expected timeframe, contact the clinic for an update.
What Do the Possible Results Mean?
A benign result means that no precancerous or cancerous cells were found in the tissue examined. In many cases, you may not need further treatment once the polyp has been removed and your symptoms have settled.
If abnormal changes are found, your next steps will depend on the type of cells identified. Hyperplasia without atypia, atypical hyperplasia or cancer each require different levels of follow-up and specialist care. Your doctor will explain what the result means for you and whether any further investigations or treatment are needed.
What Treatment Is Needed If Abnormal Cells Are Found?
Hyperplasia without atypia may be managed with progesterone-based treatment and repeat monitoring of the womb lining. Atypical hyperplasia requires specialist assessment because it can be associated with existing endometrial cancer and has a higher risk of progression. For many postmenopausal women who are suitable for surgery, hysterectomy is usually recommended, although treatment decisions depend on individual circumstances.
If cancer is confirmed, your gynaecological oncology team will discuss the most appropriate treatment options with you. These may include surgery and, depending on the type and stage of cancer, other treatments such as radiotherapy, chemotherapy or hormonal therapy. Your care plan will be based on your results, overall health and personal preferences.
What Should You Expect After Polyp Removal?
Mild period-like cramps and light bleeding or discharge are common after hysteroscopy and polyp removal. These symptoms should gradually improve, and you should follow your clinic’s advice about using sanitary pads, bathing, exercise and returning to sexual activity.
Most people can return home on the day of treatment, although recovery may take longer after sedation or a general anaesthetic. Seek medical advice if you develop heavy bleeding, worsening pelvic pain, fever or unpleasant-smelling discharge, and report any new postmenopausal bleeding even if previous results were normal.

FAQs:
1. Are endometrial polyps after menopause usually cancerous?
Most endometrial polyps found after menopause are benign, but the likelihood of abnormal cells is higher than in younger people, particularly when postmenopausal bleeding is present. Your gynaecologist will usually recommend further assessment or removal so the tissue can be examined in a laboratory.
2. Should you worry about bleeding after menopause if you have a polyp?
You should never ignore vaginal bleeding after menopause, even if it only happens once or involves light spotting. A polyp may be the cause, but you need medical assessment to rule out other conditions such as endometrial hyperplasia or cancer.
3. How are endometrial polyps diagnosed after menopause?
Your gynaecologist may recommend a transvaginal ultrasound to assess your womb lining, followed by a hysteroscopy if more detailed examination is needed. A hysteroscopy allows your clinician to look directly inside your womb, remove the polyp if appropriate and take a biopsy when required.
4. Will you always need surgery for an endometrial polyp after menopause?
Not always. Your treatment depends on factors such as whether you have bleeding, the size and appearance of the polyp, your medical history and your individual risk factors. Your gynaecologist will assess your symptoms, scan findings, polyp size and appearance, medical history and overall risk profile before discussing whether monitoring, hysteroscopic removal or further investigation is the most appropriate option for you.
5. What should you expect after endometrial polyp removal?
You may experience mild cramping and light bleeding or discharge for a short time after hysteroscopic polyp removal, and you can usually return home the same day. You should seek medical advice if you develop heavy bleeding, worsening pain, fever, unpleasant-smelling discharge or any new postmenopausal bleeding after treatment.
Final Thoughts: Early Assessment Provides Reassurance and the Right Care
Finding an endometrial polyp after menopause can understandably cause concern, but it is important to remember that most postmenopausal polyps are benign. Even so, because vaginal bleeding after menopause and certain risk factors can increase the likelihood of abnormal changes, prompt assessment is essential. Early investigation allows your gynaecologist to identify the cause of your symptoms, recommend appropriate treatment where needed, and provide reassurance when the findings are non-cancerous.
A personalised assessment helps ensure that any decision about monitoring, biopsy, or removal is based on your symptoms, scan findings, medical history, and overall level of risk.
