I'm 43 year old female and had a pap done and it says endometrial cells present what does that mean?

The cells forming the cervix are different from those inside the uterus. There is a transition zone or border where one type changes to the other. It is not unusual to see endometrial cells found in a pap smear. No problem.

What you described is a normal finding and not a cause for concern. Safe sex: https://www.hopkinsmedicine.org/health/wellness-and-prevention/safer-sex-guidelines
