Colposcopy or colcoscopy is a medical diagnostic procedure to examine an illuminated, magnified view of the cervix and the tissues of the vagina and vulva. Many premalignant lesions and malignant lesions in these areas have discernible characteristics which can be detected thorough the examination. It is done using a colposcope, which provides an enlarged view of the areas, allowing the colposcopist to visually distinguish normal from abnormal appearing tissue and take directed biopsies for further pathological examination. The main goal of colposcopy is to prevent cervical cancer by detecting precancerous lesions early and treating them. The procedure was developed in 1925 by the German physician Hans Hinselmann.
