An outline of the capacity of colposcopy in detection of early neoplastic changes at the ectocervix and the cervical os is given. Figures are presented of results reached by combined use of colposcopy and cytology in 6,536 women (divided into age groups of over and under 30 years) including histological findings. The results emphasize the need to use colposcopy as an additional method in cervical cancer detection.
