An apparatus and method for photographing the cervix for diagnostic and treatment purposes includes a speculum and a special close-up camera having a ring-shaped flash lamp surrounding its lens aperture. The outer diameter of the speculum is sufficiently large to dilate the vaginal opening and the inner diameter is adapted to surround the cervix. The innermost end of the speculum is beveled for ease of insertion and for positioning over the cervix while the opposite end is adapted for positioning adjacent the flash lamp and lens of the camera. In use, the walls of the speculum act as a fiber-optic system illuminating the cervix. The resulting photograph is actual size such that lesions and other abnormalities may be accurately measured directly on the print.
