2. Adequate colposcopy including:

   1. visualization of entire cervical transformation zone including the squamocolumnar junction
   2. visualization of entire lesion margin

3. Colposcopically visible lesion after biopsy, before treatment (Note: To ensure a colposcopically visible lesion after biopsy, the lesion should cover approximately 15% of the uterine cervix before biopsy)
