  • Safety of focal treatment [ Time Frame: six months ]
    Participants will be asked to report any adverse events following focal treatment. These events will be graded according to standard criteria (DAIDS).
  • Acceptability of focal treatment [ Time Frame: six months ]
    Participants will be asked to respond to a survey at enrollment and follow-up asking whether they are satisfied with focal treatment as an alternative method of treatment.
  • Feasibility of focal treatment [ Time Frame: enrollment ]
    Providers will be asked to provide information after each treatment regarding whether the treatment was technically feasible to perform.

Focal Ablation of Cervical Precancer
Focal Ablation of High-grade Cervical Intraepithelial Neoplasia
This is a pilot cohort study of women undergoing focal ablation for high-grade cervical intraepithelial neoplasia (HGCIN). The cohort was recruited from the UCSF Dysplasia Clinics. The standard treatment involves treatment of the entire cervix. Women with HGCIN meeting inclusion criteria were recruited for enrollment into the pilot study of focal treatment. Upon enrollment, they underwent focal ablational treatment rather than standard ablational treatment of the cervix. Follow-up visits were conducted at 2 weeks and 6 months to assess safety, feasibility, and acceptability. The 6-month recurrence rate of HGCIN will be calculated.
