What is a colposcopy or cervical biopsy?
A colposcopy is a special way of looking at your cervix by using a lighted, low-powered microscope. At the start of the process, a speculum is placed in the vagina to visualize the cervix. The microscope is used to make the cervix appear larger and allows your healthcare provider to find and then take a sample of biopsy of any abnormal areas.
