When your Pap smear results are "abnormal," the cells seen under the microscope are not typical in size or shape, and your doctor may want you to have more tests. There's no need to worry about an abnormal result. About 7% of the 50 million Pap smears done each year in the United States show abnormal results - which is far more than the number of women who actually have cervical cancer. This is because not all cervical abnormalities develop into cancer. Some types of abnormalities resolve on their own with no treatment needed. Others are more likely to turn into cancer and require further testing and possible treatment. If you have abnormal results, be sure to discuss their significance with your health care provider.
If the abnormality is thought to be minor, your GYN may do another Pap smear. If the second test shows a major change in the cervical cells, you may need to come back for a colposcopy. In a colposcopy, the doctor looks directly at the cervix with an instrument called a colposcope, which magnifies the cells of the vagina and cervix. He or she may also take a small amount of tissue from the cervix (called a biopsy) and send it to the lab for further examination.
An abnormal Pap smear usually arises from something such as HPV - which should be treated as it can increase a woman's risk of someday developing cervical cancer.
