Based on the high incidence of cervical cancer and high grade dysplasia and increased progression and incomplete treatment of CIN2 and 3 in South Africa, we propose to study the effect of cryotherapy among HIV-positive women diagnosed with CIN 1 versus regular 12 month cytology follow-up. This study will be a dual-arm, open-label, randomized clinical trial for HIV-infected women diagnosed with CIN 1 and receiving care at the Themba Lethu Clinic, Helen Joseph Hospital, Johannesburg, South Africa. CIN 1 will be identified from patients who have had a colposcopic biopsy for persistent LSIL as per standard of care.
