What is Colposcopy?
Colposcopy is a special visual examination of the cervix, vagina, and sometimes the outer lips or
vulvar area. If you have an abnormal Pap smear, you may require a colposcopy. This requires
your healthcare provider to look through an instrument called a “colposcope” which is a type of
microscope mounted on a pole. The colposcope helps your healthcare provider check for
problems, which are often very small, on the cervix and vagina and may not be seen during your
regular exam. If abnormalities are seen, a small sample of tissue, called a biopsy, is usually done.
The biopsy gives your healthcare provider important information to decide if treatment would be
necessary. Biopsies may cause mild cramping. The colposcopy exam takes about 10 to 20
minutes.
Who needs Colposcopy?
Colposcopy is most often advised for women who have had an abnormal Pap smear. An
abnormal Pap smear may be a sign of a precancerous condition that can then be successfully
treated before turning into cancer. Occasionally, a patient may be referred for colposcopy because
of some abnormal appearance of their cervix, noted during a pelvic examination.
How is Colposcopy performed?
The colposcope used in colposcopy is instrument that looks like a pair of binoculars mounted on a
pole. A speculum is placed in the vagina to hold the vaginal walls open, just as if you were
having a Pap smear done, and remains in place until the exam is finished. The colposcope is
placed a few inches in front of the vagina, but does not touch you. A repeat Pap smear may also
be done at this time, in the same way it is collected during your prior exam. Your health care
provider may place vinegar, and sometimes an iodine solution (notify your healthcare provider if
you are allergic to iodine), directly onto the cervix and vagina to identify any abnormal areas.
You may have some mild burning or tingling, but most patients do not experience this. The
provider might also adjust the colposcope by changing the magnification or looking through
different colored filters. This helps in finding suspicious areas. Sometime photographs of your
cervix, vagina, or vulva are taken during your exam and become part of your medical record.
Abnormal cells that cause cervical disease may extend up toward the lining of the uterus or womb
through an opening called the endocervical canal. This is the same birth canal that dilates when
women have vaginal childbirth. Sampling the endocervical canal may cause cramping or, rarely,
light-headedness. If abnormal areas are seen on the cervix, they often require a biopsy to make a
correct diagnosis. The biopsy takes a very small piece of tissue from the abnormal areas. If more
than one area is abnormal, several different biopsies may be performed. Any bleeding from the
biopsy sites can be stopped using silver nitrate or an iron-containing compound called Monsel’s
solution. A pathologist, who will tell your healthcare provider the final diagnosis, then sends the
biopsy specimens that are collected to the lab for processing and examination. This may take
several days or even a few weeks.
What should you expect after the biopsy?
For about three to five days following a colposcopy with biopsies you may experience some
spotting or a brown crumbly discharge, like coffee grounds, which may require you to use a
mini-pad. There are few restrictions after the procedure and you may usually go about your daily
routine. If biopsies are performed you may be restricted from certain activities until the spotting
has stopped and your cervix has time to heal. These include:
•Sexual activity (vaginal intercourse)
•Putting tampons into your vagina
•Washing or douching inside your vagina
You should call your healthcare provider if you have:
•Fever
•Bright red, heavy bleeding which is more than what you have with your period
•Bad cramps or pain that do not improve with over-the-counter medications, such as ibuprofen
What is the treatment after a Colposcopy?
The treatment following a colposcopy depends on the degree of abnormality reported on the
biopsy. For minor or low-grade abnormalities, no treatment may be necessary and only a follow
up Pap smear or HPV testing would be required. If there are greater or more severe
abnormalities, other treatment may be required including destroying surface cells of the cervix
with laser or freezing therapies. Another option includes a larger biopsy of the cervix called a
“Loop” or loop electro excision procedure (LEEP), which may be performed in the healthcare
provider’s office. A surgical conization in the operating room is needed occasionally. Your
healthcare provider will discuss these treatments with you, if any is needed. You may also wish
to read the ASCCP patient education pamphlet on LEEP.
Is Colposcopy safe for pregnant women?
As with non-pregnant women any abnormal Pap smear in pregnancy needs further examination.
Looking through the colposcope is completely safe and biopsies may be performed in pregnancy
if suspicious areas are identified. Sampling from the birth canal, such as by an endocervical
curettage, should not be performed in pregnancy. Most of the treatment methods which are used
on nonpregnant patients are not recommended during pregnancy. These treatments can usually
wait until after the pregnancy is finished. Often a repeat exam is done after the pregnancy to
determine if treatment is still necessary.
What are the risks to Colposcopy?
There are no serious risks to colposcopy, which is performed routinely in the healthcare
provider’s clinic. The most likely side effect is mild discomfort from the solutions used and
cramping or pinching from the endocervical curettage or biopsies. There may be a small amount
of spotting for a few days, but heavy bleeding is rare. The Monsel’s solution or silver nitrate used
to help stop bleeding may also cause a brown crumbly discharge for two to three days.
Is there anything I should or should not do before my Colposcopy?
If your abnormal Pap test was done by another healthcare provider, it is useful to have a copy of
the report at the time of your referral for a colposcopy. Undergoing colposcopy does not require
any special preparation. You may take over-the-counter medications like ibuprofen or
acetaminophen before the procedure to help reduce the cramping. To avoid obscuring the
abnormal cells, it is best to avoid anything in the vagina for two days prior to the procedure such
as sexual activity, intravaginal medications, tampons, or douching. Try to avoid having
colposcopy during your period, but if the bleeding is light, the exam may still be satisfactory.
