When a Pap test reveals an abnormality in the cells of the cervix, your gynecologist will likely want to perform a colposcopy, which is simply a closer examination of the cervix, vulva and vagina using a special lighted magnifying tool called a colposcope. Other reasons for performing a colposcopy may include the presence of inflammation or warts on the cervix, unexplained pain or bleeding, or benign polyps. If necessary, this in-office procedure enables your doctor to collect a small tissue sample for biopsy. Typically the examination takes under 20 minutes to perform. If a biopsy sample is taken during this time, the patient may experience some light bleeding, pain or discharge in the one or two days following the procedure. The colposcopy results may rule out the need for further examination or may indicate that the patient needs to undergo further testing and treatment.
