Your periods stopped more than a year ago, and now there has been bleeding again. It may have been a single episode, or spotting you noticed only on tissue. Either way it needs assessing, and it helps to know the actual numbers rather than the worst ones. A systematic review and meta-analysis published in JAMA Internal Medicine and indexed by Mayo Clinic found the pooled risk of endometrial cancer among women with post-menopausal bleeding was 9%, drawing on 129 studies.
Read that carefully, because both halves matter. Nine in ten women who bleed after menopause do not have cancer. But nine per cent is far too high to watch and wait, and it is why every episode gets investigated. This article explains what causes it, what the assessment involves, and what treatment looks like once the cause is known. Women in South Delhi are seen for this at PSRI Hospital, Sheikh Sarai.
| Key Takeaways |
| Any bleeding more than twelve months after your last period needs assessment, including a single episode of spotting. |
| Around nine in ten women with this symptom do not have cancer, but the tenth is the reason nobody waits. |
| A thin lining on ultrasound is reassuring; a thickened one needs the lining sampled. |
| Hysteroscopy sees the cavity directly and finds focal lesions that a blind sample can miss. |
| Most causes are benign and treatable, commonly thinning of the lining, a polyp, or hormone therapy effects. |
What Counts as Post-Menopausal Bleeding
| In plain terms |
| Menopause is confirmed after twelve consecutive months without a period. Any bleeding after that point is post-menopausal bleeding, whatever the amount. A single spot, brown discharge, or bleeding after intercourse all count. The volume does not predict the cause, so light bleeding is investigated exactly as thoroughly as heavy bleeding. |
The commonest cause is not cancer. It is atrophy, meaning the lining and vaginal tissues have thinned as oestrogen fell, leaving fragile surfaces that bleed easily. That accounts for a large share of cases.
Other frequent causes include an endometrial polyp, a submucous fibroid, thickening of the lining known as hyperplasia, an effect of hormone replacement therapy or tamoxifen, and infection. Cancer of the lining sits at the serious end of the same list, and separating these is exactly what a gynaecological assessment is for.
What the Assessment Actually Involves
Expect three steps, usually across one or two visits.
History and examination. When the bleeding happened, how much, whether you are on hormone therapy or tamoxifen, and an examination that includes the cervix and vagina, since the bleeding sometimes comes from there rather than the uterus.
Transvaginal ultrasound. This measures endometrial thickness. A thin lining makes cancer unlikely and may be enough on its own for a single episode. A thickened lining, a focal mass, or recurrent bleeding despite a thin lining moves you to the next step.
Sampling the lining. Either an outpatient endometrial biopsy or a hysteroscopy with directed biopsy.
That last distinction matters more than most women are told. A blind biopsy samples the lining generally and is good at detecting disease spread across the whole surface. It can miss a polyp or a focal lesion sitting in one corner. A hysteroscopy views the cavity directly, so a focal abnormality can be seen and removed in the same sitting.
| Finding | What it usually means | Typical treatment |
| Thin, atrophic lining | Commonest cause, benign | Vaginal oestrogen, reassurance, review if it recurs |
| Endometrial polyp | Benign in most cases | Hysteroscopic removal, tissue sent for pathology |
| Submucous fibroid | Benign | Hysteroscopic resection |
| Hyperplasia without atypia | Overgrowth, not cancer | Progestogen, often an intrauterine system, with follow-up |
| Hyperplasia with atypia | Pre-cancerous change | Discussed as a separate plan, often surgical |
| Endometrial cancer | The 9% the pathway exists to find | Referred to gynae-oncology |
Treatment, by Cause
Because the causes differ so widely, there is no single treatment for post-menopausal bleeding. What there is instead is a sequence: find the cause, then treat that.
For atrophy, low-dose vaginal oestrogen usually settles the bleeding and the dryness alongside it. For a polyp or a submucous fibroid, hysteroscopic removal is usually day care and doubles as the diagnosis, because whatever is removed goes for pathology. For hyperplasia without atypia, a progestogen-releasing intrauterine system is commonly used, with repeat sampling to confirm the lining has responded.
Where hormone therapy is the trigger, adjusting the regimen often resolves it, though that decision belongs with whoever prescribes it.
Dr. Rahul Manchanda is an MD gynaecologist with dedicated international training in hysteroscopy and laparoscopy who has written textbooks on hysteroscopy. The practical relevance is that where a focal lesion is suspected, seeing the cavity tends to settle the question in one sitting rather than two.
What Not to Do
Three things delay diagnosis more than anything else.
Assuming it is “just the change”. Menopause explains periods stopping, not restarting. Putting it down to stress or a missed hormone tablet. Waiting to see whether it happens again, which is the commonest reason women present months later than they could have.
One more is worth naming. A previous normal smear does not cover this. A smear screens the cervix, not the lining of the uterus, and the two are different organs.
Future Trends in Assessing Post-Menopausal Bleeding
Assessment is moving out of theatre. Office hysteroscopy with miniature scopes now allows many women to have the cavity examined, and a polyp removed, without general anaesthesia or a theatre booking. Improved ultrasound protocols, including saline infusion sonography, are sharpening the decision about who needs a hysteroscopy at all. Research into endometrial sampling devices and molecular markers continues, with the aim of ruling out cancer with less intervention.
Conclusion
Bleeding after menopause is common, usually benign, and never something to watch and wait through. The nine per cent figure is the whole argument for prompt assessment, and the ninety-one per cent is the reason not to panic while you arrange it. Get the ultrasound, get the lining assessed if the scan indicates it, and treat whatever is found. Most women in this position are reassured and treated for something benign.
| Do not wait for it to happen twice |
| If you have had any bleeding more than a year after your last period, book an assessment now rather than after a second episode. Bring a note of the dates and amount, along with any hormone therapy you take. Consultations are available at PSRI Hospital, Sheikh Sarai, South Delhi. Call or WhatsApp 097170 94237. |
Frequently Asked Questions (FAQs)
Q. I only spotted once. Does that still need checking?
A. Yes. The amount of bleeding does not predict the cause, and a single episode is assessed the same way as repeated bleeding.
Q. Does bleeding after menopause mean cancer?
A. Usually not. Pooled data puts the risk of endometrial cancer at around 9%, so the large majority of women have a benign cause, most commonly thinning of the lining.
Q. What thickness of lining is considered normal after menopause?
A. Units use a threshold, commonly around 4 to 5 mm, below which cancer is unlikely. Your own report should be interpreted alongside your symptoms rather than as a number in isolation.
Q. Is hysteroscopy painful?
A. An office hysteroscopy without anaesthesia usually feels like strong period cramping for a few minutes. Where anaesthesia is used, nothing is felt at the time and mild cramping follows for a day or two.
Q. I am on HRT and bleeding. Is that expected?
A. Some regimens cause scheduled bleeding, and unscheduled bleeding in the first months is not unusual. It still needs assessing rather than assuming, particularly if it persists beyond six months or starts after a settled period.
Q. My smear was normal last year. Is that enough?
A. No. A smear screens the cervix for pre-cancerous change. It says nothing about the lining of the uterus, which is where post-menopausal bleeding usually originates.
