I found this which might help alleviate some of your fears

What is the normal endometrial thickness postmenopausal without bleeding?

Conclusions: In a postmenopausal woman without vaginal bleeding, if the endometrium measures > 11 mm a biopsy should be considered as the risk of cancer is 6.7%, whereas if

the endometrium measures < or = 11 mm a biopsy is not needed as the risk of cancer is

extremely low.

How thick is too thick? When endometrial thickness should

As your lining is less than 11mm with no postmenopausal bleeding the chance of cancer seems to be extremely low.  

I have found the NHS are very well organised with postmenopausal bleeding and everything falls into place, they take it very seriously.  That you’ve had no bleeding they obviously don’t think it should be anything too serious x

Thanks for this information. I know this is reassuring but would feel happier if they coiled tell me why the thickness of my womb has increased in the last 2.5 years. I think for my own peace of mind I will probably have to pay for the hysteroscopy to be performed as a private patient. Hope everything is good with you and thanks for your support. 

5.3mm isn’t very thick in the grand scheme of things….could you not ask your GP to arrange a hysteroscopy on the NHS but on the routine list rather than the urgent one.  You didn’t say why you had the ultrasound in the first place, was there an underlying condition or something?  

My lining was 7.6mm back in 2019 and 8.5 in January 2023 but my investigations both times were due to postmenopausal bleeding, that is usually the trigger for further investigations..I had poly ps and then polyps again, my histology after hysterectomy then said there was also a fibroid which I knew nothing about ‍♀️

Your lining could be slightly thicker due to hyperplasia but you won’t know without a biopsy being done..I had atypical hyperplasia (pre cancerous cells) I one of my polyps, I was given a mirena coil between diagnosis and my hysterectomy…upon biopsy after hysterectomy there was no hyperplasia in my womb, now that could be due to the mirena coil as it’s known to tackle hyperplasia very successfully, or it could be that it was contained due in the one polyp I had removed (which is what my consultant thinks as I had 3 womb lining biopsies taken between January and June this year and they were all normal..perhaps you could discuss possible hyperplasia with your GP and ask if you can be referred to see someone on the NHS?

Thanks so much for your detailed response. I went to the GP because my stomach had become much larger and I was getting bloating and indigestion problems. I also had frequent and urgent urination and my bladder wasn’t emptying fully. I am waiting for an urology appointment to investigate the bladder problem but my GP thought that because there had been a slight increase in my CA125 reading, albeit still well within the normal range my ovaries and uterus should be checked. I think it is unlikely f that I will get a hysteroscopy via the NHS but I will ask. Ii just wish the price of a private procedure wasn’t so expensive. 

Thanks for your encouraging and supportive message. I have been doing a bit of research myself since I posted my original message and think I may be on to something. The gynaecologist I saw privately this week couldn’t explain why my uterus lining would nearly double in the past 2.5 years. I didn’t mention to him that I have gallbladder stones or polyps because the clinic letter notifying me of this  arrived after the appointment. Apparently if you have gallbladder disease this can significantly increase your risk of uterine cancer. This has made me more determined than ever to take preventive action even if the NHS route is not an option. 

I had a hysteroscopy done privately it was £2900 so similar price you have been quoted you do have more options for pain relief I had a spinal block could have had ga also.Nhs only recommend taking paracetamol
