Cervical cancer is the second most common cancer in women worldwide.Prevention of invasive cancer by early detection and treatment of cervical intraepithelial neoplasia (CIN)currently offers the most cost effective, long term strategy for cervical cancer control. Colposcopy is a widely used method for the detection of early cervical neoplasia. Lack of standard diagnostic protocols causes interpretation difficulties.The present study was carried out to minimize disagreements and make colposcopic assessment quick,accurate,economic, easy and useful for follow-up cases. With the present modification in reporting and considering its high sensitivity, colposcopy should be made compulsory as a screening tool for diagnosis of cervical cancer in all secondary and tertiary-care hospitals.This method is also very useful for day to day binocular colposcopy practice ,hence it is hoped that this monograph finds range of uses,for short teaching courses of health care personnel, medical and nursing students, medical and general gynecology practitioners who wish to learn colposcopy and contribute in cervical cancer prevention.
