Pap smear screening targets the cervix. The test collects cells from the cervix, especially the transformation zone where the type of epithelium changes, because most precancerous cervical changes occur there and can be seen under a microscope as dysplasia or other abnormalities. The uterus, ovaries, and vagina are not the primary targets of this screening; the cervical epithelium is what's being assessed to catch precancerous lesions early.
