Bleeding After Menopause: Why You Should Always Get It Checked – and the New Test That Could Make Investigations Easier
You haven't had a period for well over a year. Then one day, you notice blood.
Maybe it's just a tiny pink mark when you wipe. Perhaps there's some brown discharge. Or maybe it looks enough like a period to make you wonder what on earth your hormones are doing now.
It would be very easy to think: Surely this is just another weird menopause thing?
But this is one symptom you shouldn't simply put down to hormones.
Any vaginal bleeding after menopause should be checked by your GP — even if it's only happened once and even if it's only a tiny amount.
The reassuring part is that most women who experience postmenopausal bleeding do not have cancer. The new UK research we're about to look at found womb cancer in around 5% of the women investigated. The Guardian
But because bleeding can be an early sign of womb cancer, doctors need to find out what's causing it.
And now researchers in Manchester may have found a much simpler way to help them do that.
First things first: what counts as postmenopausal bleeding?
Menopause is generally diagnosed once you've gone 12 months without a period.
After that point, vaginal bleeding isn't considered a normal period returning.
The NHS says you should see your GP if you experience bleeding after menopause even if:
- it's only happened once
- there's only a small amount of blood
- you're not sure whether it's actually blood
- it's pink or brown discharge
- you don't have any other symptoms.
The NHS guidance on postmenopausal bleeding is deliberately cautious because, while postmenopausal bleeding is usually caused by something other than cancer, cancer is one of the possible causes and is generally easier to treat when diagnosed early. nhs.uk
So does bleeding after menopause mean womb cancer?
No.
This is the bit that's important not to lose among scary headlines.
In the new study, researchers recruited 1,864 women experiencing postmenopausal bleeding at seven hospitals in north-west England.
Of those women, 99 were diagnosed with womb cancer — roughly 5%. The Guardian
In other words, the overwhelming majority weren't.
There are several other reasons you might bleed after menopause, including changes to the tissues of the vagina or womb lining, polyps and other gynaecological conditions.
But you can't reliably tell from the amount or appearance of the bleeding what's causing it.
That's why it needs checking.
What happens at the moment?
If you go to your GP with postmenopausal bleeding, you'll usually be referred for further investigation.
Depending on your circumstances, that can involve an internal — transvaginal — ultrasound, a biopsy of the womb lining and sometimes a hysteroscopy, where a thin camera is passed through the cervix to examine the inside of the womb.
These tests are important.
But they're not exactly something anybody looks forward to.
Some women find them uncomfortable and others find procedures such as hysteroscopy painful or distressing.
And because most women referred with postmenopausal bleeding won't turn out to have womb cancer, researchers have been trying to find a reliable way to work out who is most likely to need further invasive investigation.
Which brings us to the new research.
A urine sample and vaginal sample could help identify womb cancer
Researchers from the University of Manchester and Manchester University NHS Foundation Trust have developed a test that examines cells found in urine and vaginal fluid.
Women taking part provided the samples before undergoing the usual hospital investigations.
Specialist cytologists then examined the cells without knowing which women had subsequently been diagnosed with cancer.
When the urine and vaginal-fluid results were combined, the test identified 80 of the 99 womb cancers. It also correctly returned a negative result for 93% of women who did not have womb cancer. The Guardian
Perhaps even more encouragingly, the test was particularly good at detecting the cancers doctors most don't want to miss.
It detected 95.8% of high-grade tumours and 96.4% of cancers that had already spread beyond the uterus. The Independent
That's potentially very useful.
Does this mean we can swap a hysteroscopy for a urine test?
Unfortunately, not yet.
And this is where some of the headlines need a little context.
The researchers themselves say the test isn't currently accurate enough to rule out womb cancer on its own.
Missing 19 of the 99 cancers in the study means it couldn't simply be used as:
Negative test = definitely no cancer.
Instead, the researchers see its potential as a triage test.
That could mean women whose results suggest a higher risk are fast-tracked for urgent investigations, while women at lower risk might initially avoid invasive procedures and instead have repeat sampling or further assessment if their bleeding continues. The Guardian
More research is needed before we know whether that can safely become routine NHS practice.
There's another important limitation
The samples in this study weren't being assessed by just anyone.
They were examined by highly trained specialist cytologists.
Researchers therefore don't yet know whether the same level of accuracy could be reproduced everywhere the test might eventually be used.
It has also only been studied in women who already had symptoms — specifically postmenopausal bleeding.
So this isn't a new general womb-cancer screening test for women without symptoms. The Guardian
That's an important distinction.
The results in Black women were particularly interesting
There was another finding that deserves attention.
The new test detected all of the cancers among the Black women in the study, while maintaining 96% specificity. However, this was a relatively small subgroup, so the result needs further confirmation. The Independent
Why does that matter?
A linked analysis from the researchers found that the transvaginal ultrasound currently used to investigate postmenopausal bleeding was more likely to produce an inconclusive result in Black women.
Among women who underwent ultrasound, the womb lining couldn't be measured or an abnormality couldn't be excluded in 11% of Black women compared with 2% of White women. Researchers stressed the numbers were small and further research is needed. Scimex
That could make finding diagnostic approaches that work equally well across different ethnic groups especially important.
What exactly is womb cancer?
Womb cancer is also called uterine cancer, and the most common type is endometrial cancer, which develops in the lining of the womb.
Postmenopausal bleeding is its most recognised warning symptom.
That doesn't mean every episode of bleeding is cancer.
Far from it.
But it does explain why doctors take it seriously.
And there is an important advantage to that very obvious warning sign: it can prompt women to seek medical help relatively early.
What if I'm taking HRT?
Don't automatically assume bleeding is harmless because you're taking HRT.
Bleeding can occur when starting or changing some types of HRT, and what's expected depends on the HRT regimen you're using and how long you've been taking it.
But unexpected, persistent or new bleeding should still be discussed with a healthcare professional, particularly if you've previously been bleed-free.
Your GP or menopause clinician can decide whether it needs investigating.
The important thing is not to diagnose the cause yourself.
“It's hardly anything. Do I really need to bother the GP?”
Yes.
This is probably the most useful thing to remember from this entire article.
- You don't need to be soaking through pads.
- You don't need to have pain.
- You don't need to bleed repeatedly.
- You don't need to wait to see whether it happens again.
- The NHS specifically advises women to see a GP after even one episode of postmenopausal bleeding, however small. nhs.uk
- You aren't wasting anybody's time.
This is precisely the sort of symptom doctors want checked.
The Hot Again take
Menopause comes with such an extraordinary collection of symptoms that it's very easy to develop a habit of thinking:
Oh. That's probably hormones too.
Hot flush? - Menopause.
Dry eyes? - Possibly menopause.
Brain fog? - Very possibly.
Suddenly awake at 3am contemplating every questionable decision you've made since 1997? - We know the drill.
But bleeding after menopause belongs in a different category.
It usually won't turn out to be cancer. In this large UK study, about 95% of the women investigated didn't have womb cancer. The Guardian
That's genuinely reassuring. But it still needs investigating.
And this new research is exciting not because it means women can ignore bleeding or diagnose themselves with a urine test, but because it could eventually make that investigation quicker, kinder and less invasive.
For thousands of women facing the frightening wait between “I've found blood” and “it's not cancer”, that could make an enormous difference.
So the message is actually quite simple:
If you've gone through menopause and you bleed, get it checked.
Chances are, it won't be cancer.
But this is one symptom worth being cautious about.
Because sometimes “It's probably nothing” and “I should get this checked” can both be true.
