Steps to determine eligibility for ablative treatment Ė Criteria used to determine eligibility for ablative treatment

  

Ablative treatment can be used to treat an abnormal transformation zone provided the following criteria are fulfilled:

  • The squamocolumnar junction (SCJ) should be fully visible and should be on the ectocervix or at the external os.
  • If there is a visible lesion, it should be on the ectocervix without any extension to the endocervix or to the vagina.
  • If there is a visible lesion, it should not occupy more than 75% of the ectocervix.
  • The size of the lesion should be such that it can be fully covered by the tip of the largest cryotherapy probe (applicable for cryotherapy only).
  • There should not be any suspicion of invasive cancer.


Please note that an HPV positive cervix may not have any lesion. Only the first criteria (visibility and location of SCJ) will determine suitability of treatment.
