About Pap Smears


Pap smear is basically a screening test for changes in the outer layer of the cervix that can progress to cervical cancer, a common form of cancer in women that is easily treated if diagnosed in the "pre-cancer" or early stages. All women who are sexually active or are over the age of 18 should see their doctors yearly to have a pap smear. Some groups recommend that this screening may be done only every three years after three consecutive normal tests--but this is a topic you must discuss with your own doctor.

An abnormal Pap smear does NOT mean that you have cervical cancer. Cervical cancer develops through many different stages of abnormality and usually does this slowly enough that yearly screening is sufficient to detect it at an early stage. Certain infections can cause the pap smear to be abnormal. Cervicitis caused by bacteria can produce changes in the cervix which yield an abnormal test. A virus called HPV , which can also cause cervical warts, is thought to create changes in the cells of the cervix which can lead to cervical cancer, and so give you an abnormal pap smear. If your doctor tells you that you have an abnormal pap smear, she/he will probably recommend that you have a repeat test done in three months, depending on the level of the abnormality. During this waiting period you may be asked to use a medication to treat an infection if this is appropriate to your results. If the repeat test is also abnormal, or if the initial test warrants it, you will be scheduled for Colposcopy, which involves your doctor using a colposcope to better visualize your cervix. A colposcope is a microscope with a light on it that helps your gynecologist to see areas that appear abnormal, and during this examination small biopsies may be taken of suspicious areas, if any are seen. Depending on the results of these biopsies, treatment options will be discussed with you. The various treatments available are beyond the scope of this discussion, but most involve preserving your uterus unless the changes have progressed to cancer.
