A colposcope is a binocular viewing instrument used to magnify the cervix for examination. Colposcopy is often performed after an abnormal cervical smear test to look for signs of CIN. During the procedure, which is painless and lasts for 15–30 minutes, your doctor may paint solutions on to the cervix to highlight abnormal areas. A sample of cervical tissue may also be taken, or abnormal areas of the cervix may be treated (see Treating CIN).
