Colposcopy is a procedure that gives your doctor a magnified view of your cervix. It's done using a lighted microscope called a colposcope. In most cases, a sample of cervical cells is taken during a biopsy. The sample can then be studied in a lab. If any problems are found, you and your doctor will discuss treatment choices. It usually takes less than 30 minutes, and you can often go back to your normal routine right away.

Colposcopy is usually done as a follow-up exam to help find the cause of an abnormal Pap test. Results of an abnormal Pap test can mean that the cells don't appear normal or that there are cancer cells. Abnormal cells can also be caused by infections. HPV (human papillomavirus) is a large family of viruses that can be passed from person to person through sex. HPV can cause genital warts. It can also cause changes in cervical cells. If an HPV test is positive and the Pap test is abnormal, a colposcopy may be recommended. Colposcopy is also used to evaluate other problems. These include:

• Pain or bleeding during sex
• Postmenopausal bleeding
• Unexplained abnormal lower genital tract bleeding
• Sore (lesion) on the vulva or vagina
• Persistent abnormal vaginal discharge

Problems after colposcopy are very rare, but can include:

• Bleeding (if a biopsy is done)
• Infection

Colposcopy is normally done in your doctor's office. It will be scheduled for a time when you're not having your menstrual period. You may be asked to sign a form giving your consent to have the procedure. A day or two before the procedure, your doctor may also ask you to:

• Not have sex.
• Stop using tampons.
• Not use creams or other vaginal medicines.
• Not clean out the vagina with water or other fluids (douche).
• Take over-the-counter pain medicines 1 or 2 hours before the procedure.

• You will be asked to lie on an exam table with your knees bent, just as you do for a Pap test.
• A tool called a speculum is inserted into the vagina to hold it open.
• A vinegar or iodine solution is applied to the cervix to make the abnormal cells easier to see. You may feel pressure or a slight burning for a few moments. In some cases, the cervix may be numbed first with an anesthetic.
• The cervix is looked at through the colposcope. This is placed outside the vagina.
• If your doctor sees abnormal areas on your cervix, a biopsy will be done. You may feel a slight pinch and cramping. The tissue sample is sent to a lab for study.
• An endocervical curettage may also be done at the time of colposcopy. In this procedure, a tool is put into the endocervical canal to get a sample of cells from the endocervix. This area can't be seen with a colposcope.
• You may feel slight pinching or cramping during the biopsy. Medicine or a thick paste may be applied to the biopsy site to stop bleeding.

• If you feel lightheaded or dizzy, you can rest on the table until you're ready to sit up.
• If a biopsy was done, you may have mild cramping or light bleeding for a few days. You may also have a thick, dark discharge from the medicine used to stop bleeding at the biopsy site.
• Use pads or panty liners, but not tampons, for at least the first 24 hours.
• If you have any discomfort, over-the-counter pain medicine can provide relief.
• Ask your doctor when you can have sex again.

If a biopsy was done, your doctor will get the lab report in 1 or 2 weeks. You and your doctor can then discuss the results. In some cases, you may be scheduled for more tests or treatment. Be sure to keep follow-up appointments with your doctor.

Contact your doctor if you have:

• Heavy vaginal bleeding (more than 1 pad an hour for 2 hours).
• Severe or increasing pelvic pain.
• A fever over 100.4°F (38°C), or higher, or as directed by your doctor.
• Bad-smelling or unusual vaginal discharge.
