Abnormal Pap smear: colposcopy and cryosurgery

Colposcopic evaluation of patients with abnormal Papanicolaou smears permits the physician to visualize cervical lesions and determine the extent of intraepithelial neoplasia. Through the use of colposcopy with cryotherapy, many patients with cervical intraepithelial neoplasia may avoid a more invasive form of treatment. Family physicians should become familiar with colposcopic technique so that they can select patients who are suitable for local treatment with cryotherapy.
