Experience using cryotherapy for treatment of cervical precancerous lesions in low-resource settings

Cervical cancer can be successfully prevented if timely identification of precancerous lesions is followed by effective treatment. In many developing countries, treatment of precancer is neglected because therapeutic services are unavailable, inaccessible, inappropriate, or inadequately linked to screening services. One of the main focuses of the Alliance for Cervical Cancer Prevention (ACCP) has been to ensure that safe and effective methods of treatment for precancer are both available and accessible to women who need them. Cryotherapy, in use for the past 40 years, is a relatively simple, safe, effective, acceptable, and appropriate outpatient procedure for the treatment of precancer. ACCP studies conducted in more than a dozen developing countries show that cryotherapy for precancer can be performed safely and effectively as an outpatient procedure at all levels of health facilities by trained and competent midlevel providers, thus increasing availability and accessibility to precancer treatment services.
