pap definition
A Pap smear, also called a Pap test, is a procedure to test for cervical cancer in women. A Pap smear involves collecting cells from your cervix â the lower, narrow end of your uterus that's at the top of your vagina. Detecting cervical cancer early with a Pap smear gives you a greater chance at a cure. A Pap smear can also detect changes in your cervical cells that suggest cancer may develop in the future.
