colpo- refers to:
Colposcopy is a gynecological procedure that illuminates and magnifies the vulva, vaginal walls, and uterine cervix in order to detect and examine abnormalities of these structures. The cervix is the base of the womb (uterus) and leads out to the birth canal (vagina). During colposcopy, special tests [acetic acid wash, use of color filters, and sampling (biopsy) of tissues] can be done.
