A colposcopy is a procedure that uses a colposcope (a lighted magnifying instrument) to examine the vulva, the vagina and cervix. A colposcopy is done after an abnormal Pap test or a positive HPV test suggests a precancerous condition of the cervix or cervical cancer.
Colposcopy is done to: 1  Look at the cervix for problem areas when a Pap test was abnormal. 2  Check a sore or other problem (such as genital warts) found on or around the vagina and cervix. 3  Follow up on abnormal areas seen on a previous colposcopy. 4  Look at the cervix for problem areas if an HPV test shows a high-risk type of HPV is present.
