If endometrial cells are not cancerous why would my doctor be concerned about it my hpv was negative pap said normal i do have large fibroids premenopausal 51 so confused as gynecologist not concerned found the cells on pap had sex that am before pap?

Some basics: The womb is an organ with several tissue types. The endometrial lining (tall cells) are located inside while the cervix (outer opening) is lined by a different flatter cell type. Endometrial cells shed/fall out during menses & are occasionally found on a pap smear. Their presence does not indicate cancer but sometimes lead a doc to do an ultrasound to verify it is not an issue.
