DCF will be done during the routine colposcopy in the outpatient clinic. A digital colposcope (DC) device will be used to take a sequence of images of the cervix and vagina. (A DC is a digital camera connected to the colposcope with a specialized light source. It will shine light on the cervix and acquire a sequence images). The images will tell doctors about the cells and structure of the tissue. After the first set of images, acetic acid will be applied to the cervix so that lesions show up better, and 1-2 minutes later more readings will be taken.
