Pap smear
DEFINITION
A Pap Smear is a test where a sample of cells is collected
from around the cervix (the small opening between the uterus and
the vagina) and smeared onto a glass slide. This smear is then
examined under a microscope for any abnormalities. The Pap smear is
named after its founder, Dr Papanicolaou.

DESCRIPTION
Pap Smears are used to detect changes in the cells of the
cervix, which may lead to cervical cancer if untreated. Cervical
cancer is very slow to develop. Changes occurring in the cervical
cells, which are not yet cancerous, are called pre-cancerous cells,
cervical intraepithelial neoplasia (CIN), or cervical dysplasia.
Pap Smears can detect up to 90% of these changes. The cervix can
then be treated to remove the affected cells, making cervical
cancer one of the most preventable of all cancers. The majority of
women who develop cervical cancer have never had a Pap Smear, or
haven’t had one for more than 10 years.

Who should have a Pap Smear?
- All women who have ever been sexually active, including women
with only one partner, and those who no longer have sex. - Women after menopause.
- Women who have had a hysterectomy may still need a Pap Smear if
the cervix was not removed. Discuss this with your Doctor.
How is it done?
All General Practitioners and some Specialist Nurses can
perform Pap Smears.
perform Pap Smears.
- The woman lies on her back with her knees drawn up and
apart. - An instrument called a speculum is inserted into the vagina.
This holds the walls of the vagina apart and enables the Doctor or
Nurse to see the cervix. This may cause some discomfort, but should
not be painful. Most pain is experienced when the woman is nervous
and tenses the vaginal muscles. - Some cells are gently taken from around the cervix using a
small spatula or brush. The cervix itself has few pain receptors,
so this usually cannot be felt. - The cells are smeared on to a glass slide, which is then sent
to the laboratory for testing. - Some doctors will also perform a full pelvic examination, to
check the size and position of the ovaries and uterus. - The procedure is done in the Doctor’s office, and takes about
10 minutes from start to finish.
What about the results?
The results of the Pap Smear test take a few days. Your Doctor
will let you know when to telephone for the results.

What if my Smear is abnormal?
If you have an abnormal Pap Smear, DO NOT PANIC. Most abnormal
Smears are NOT cancer. Depending on the results, your Doctor may
choose to repeat the Smear again in a few months, or may refer you
to a Gynaecologist for further assessment. See the Cervical
Dysplasia topic on the Healthpoint for further information.

NOTES
Pap Smears are not 100% accurate, and occasionally a
false-negative result may occur. In women who have regular smears,
this is not usually a problem, as any abnormalities will be picked
up at the next test, before anything serious has developed. If your
Doctor is concerned about the accuracy of the results, the test can
be repeated in a few weeks or months. Menstruation, recent
intercourse and vaginal infections such as thrush can all affect
the accuracy of a Pap Smear. Ask your Doctor when the best time for
your Pap Smear is.
