Cervical intraepithelial neoplasia (CIN); Precancerous changes of the cervix
There are usually no symptoms.
A pelvic examination is usually normal.
A Pap smear shows abnormal cells. A colposcopy-directed biopsy is done to confirm the condition and determine its severity.
Other tests may be done to find out if the abnormal cells have spread outside the cervix:
