How does HRT relate to the thickening of the uterine lining in endometrial cancer?
Hormone replacement therapy (HRT) can affect the thickness of the uterine lining (endometrium). Estrogen in HRT can cause the lining to thicken, which is something doctors monitor closely — especially for those with endometrial cancer. Here's what's important to know about endometrial thickness and HRT:
- For postmenopausal people not on HRT, a lining thicker than 5mm (with bleeding) or 11mm (without bleeding) raises concern
- For those on HRT, up to 8mm may still be considered within normal range
- A thicker lining increases the risk of endometrial cancer, so regular monitoring is essential
Because HRT can influence lining thickness, it's really important to have open conversations with your care team about whether HRT is appropriate for your specific situation. They can weigh the benefits against the risks and monitor your lining regularly through ultrasound.
Any unusual vaginal bleeding while on HRT should be reported to your doctor promptly — it's always better to flag it early.
