Hi Northerngirl, I've just had the same diagnosis as you, today. 6.5mm thickness after TVS. Have to have my hysteroscopy under gen anaesthetic due to vaginal atrophy, the gynae said combined with not having children, the pain would be too bad, so I'm glad I'll be knocked out!!
I had spotting for a couple of months followed by a massive heavy period last month. On HRT for 2 years which I decided mainly due to quality of life (or lack of it)
Gynae said to stop hrt and tbh I doubt I'll go back on after this.
Like you, I wasn't given any other diagnosis except possibly cancer. I'm having the procedure with 2 weeks and had the pre op today while at the hospital.
Try not to overthink this - with only 8mm thickness there is only 7% chance of it being cancer, so very low. I've learned over the years that the medical profession always give you worst case scenario. I had to sign the consent form which put more emphasis on what might go wrong instead of the procedure itself. I'm sure with both of us, it's unlikely to be cancer, other yhan bleeding I gave had no other symptoms. Apparently there is a high chance that I wasn't taking enough progesterone, hence thickening, too much oestrogen- 4 pumps daily, hence bleeding. It may be polyps.
Try to do some reading here if you can, lots of sound advice from women who have been through the same.
Will you update when you've had your procedure so I know how you are?
Sending you virtual hugs, I hope you can settle as you process the information you have.
