Colposcopy is a diagnostic tool used to help physicians understand the significance of an abnormal PAP test. A low power microscope is used to examine the cervix or vagina. If abnormalities are found, a biopsy may be done where a very small piece of tissue is removed and sent for study with a powerful microscope. The results of this exam helps determine the significance of an abnormal PAP and to determine what treatment if any is appropriate. Colposcopy with or without biopsy helps us in the detection of and subsequent treatment of cancer related abnormalities of the cervix, vagina, or external genitalia.
