Had a vaginal ultrasound on uterus they found no tumors no masses and no lesions is that good? Found endometrial cells in Pap that’s why she did ultrasound. Tried to do a endometrial biopsy but couldn’t due to large fibroid in the way

Does not add up. Ultrasound did not reveal fiborid but could not do endometrial biopsy due to fibroid are mutually contradictory statements. It would be prudent to discuss it with your doctor. Lack of tumors or masses on ultrasound is good.
