Pap smear

A Pap smear is a method to screen for cervical cancer. Squamous cells (flat, scale-like cells) are obtained from the outer surface of the cervix as well as columnar cells (tall, thin cells) from the inner canal leading to the uterus. The junction where these two cell types meet is called the transformation zone and is where most cell abnormalities are found.
