Follow-up after treatment of high-grade cervical dysplasia: The utility of six-month colposcopy and cytology and routine 12-month colposcopy.

There may be a delay in detection of persistent/recurrent CIN2/3 in a small number of cases without six-month colposcopy and cytology; however, it is not likely to negatively impact overall clinical outcome. Co-testing at 12 months following treatment of CIN2/3 without colposcopy is safe and routine colposcopy at collection of the co-test can be omitted.
