Abnormal Pap Smears

There are a number of ways to remove the abnormal cells created by dysplasia. They include:

  • Loop excisionThis technique uses a fine wire loop with electrical energy flowing through it to remove the abnormal area of the cervix. The removed tissue is sent to the laboratory for examination.
  • Cone biopsy This is an outpatient surgical procedure in which a cone-shaped section of the cervix is removed using a scalpel. The tissue is then sent to the laboratory for examination.
  • Laser therapy Laser therapy uses a tiny beam of light to vaporize abnormal cells. The laser is directed through a colposcope so that the area and depth of treatment can be controlled precisely.
  • Cryotherapy In cryotherapy, a probe is used to cool the cervix to sub-zero temperatures. The cells damaged by freezing are shed over the next month in a heavy watery discharge.
