Hello. Mine was measured at 17 and unfortunately endometrial cancer was identified. Don’t wait until the lining gets thicker to do the biopsy. I don’t like to share negative experiences but I had spotting first in 2021, had ultrasound and was told everything was ok. See you in a year (spotting had stopped). Wish I had thought to ask for a biopsy or at least repeat ultrasound in 3-6 months to determine cause vs waiting a year (when coincidentally the spotting started again) . When spotting started again went back and had the hysteroscopy and d@c And unfortunately endometrial cancer was identified. had a radical hysterectomy Dec 23 2022 and final pathology identified stage 3 endometrial cancer. Had I had the biopsy in 2021 could chance it would have been caught at stage 1. Good news finished chemo in may Just finished external beam radiation Tuesday and will finish up with brachytherapy in a couple of weeks. Have been lucky chemo and radiation have been pretty easy My advice. Don’t wait fir the lining to get thicker if you can get the biopsy now. Will be thinking of you on Monday

Sorry forgot to answer this question. When first ultrasound was done lining was 7. Year later lining was 17
