Colposcopy is a procedure to closely examine your cervix, vagina and vulva for signs of disease. During colposcopy, your doctor uses a special instrument called a colposcope.
Your doctor may recommend colposcopy if your Pap test has shown abnormal results. If your doctor finds an unusual area of cells during colposcopy, a sample of tissue can be collected for laboratory testing (biopsy).

Your doctor may recommend colposcopy if a Pap test or pelvic exam revealed abnormalities. Colposcopy can be used to diagnose: Cervical cancer Genital warts Inflammation of the cervix (cervicitis) Precancerous changes in the tissue of the cervix Precancerous changes in the tissue of the vagina Precancerous changes of the vulva Vaginal cancer Vulvar cancer

To prepare for your colposcopy, your doctor may recommend that you:
Avoid scheduling your colposcopy during your period.
Don’t have vaginal intercourse the day or two before your colposcopy.
Don’t use tampons the day or two before your colposcopy.
Take an over-the-counter pain reliever, such as ibuprofen (Advil, Motrin, others) or acetaminophen (Tylenol, others) before going to your colposcopy appointment.

Colposcopy is usually done in a doctor’s office and the procedure typically takes 10 to 20 minutes. You’ll lie on your back on a table with your feet in supports, just as during a pelvic exam or Pap test.
The doctor places a metal speculum in your vagina. The speculum holds open the walls of your vagina so that your doctor can see your cervix.
Your doctor positions the special magnifying instrument, called a colposcope, a few inches away from your vulva. A bright light is shown into your vagina and your doctor looks through the lens.
Your cervix and vagina are swabbed with cotton to clear away any mucus. Your doctor may apply a solution of vinegar or another type of solution to the area. This may cause a burning or tingling sensation. The solution helps highlight any areas of suspicious cells.

If your doctor finds a suspicious area, a small sample of tissue may be collected for laboratory testing. To collect the tissue, your doctor uses a sharp biopsy instrument to remove a small piece of tissue. If there are multiple suspicious areas, your doctor may take multiple biopsy samples.
What you feel during a biopsy depends on what type of tissue is being removed:

Cervical biopsy. A cervical biopsy won’t hurt, but you may feel some pressure or cramping.
Vaginal biopsy. Most of the vagina has little sensation and you won’t feel pain during the biopsy. But a biopsy of the lower portion of the vagina or the vulva can cause pain, so your doctor may administer a local anesthetic to numb the area.
Your doctor may apply a chemical to the biopsy area to limit bleeding.

If your doctor didn't take a biopsy sample during your colposcopy, you won't have any restrictions on your activity once your exam is complete. You may experience some spotting or very light bleeding from your vagina in the next day or two.
If you had a biopsy sample taken during your colposcopy, you may experience:
-Vaginal or vulvar pain that lasts one or two days
-Light bleeding from your vagina that lasts a few days
-A dark discharge from your vagina
Use a pad to catch any blood or discharge. Avoid tampons, douching and having vaginal intercourse for a week after your biopsy.

The results of your colposcopy will determine whether you'll need any further testing and treatment.
