Colposcopy is a procedure that gives your health care provider a magnified view of the cervix. It is 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 health care provider will discuss treatment options. 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 do not appear normal or that there are cancerous 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 sexual intercourse, or a lesion on the vulva or vagina.
Problems after colposcopy are very rare, but can include:
Bleeding (if a biopsy is done)
Colposcopy is normally done in your health care provider’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 2 before the procedure, your health care provider may also ask you to:
Avoid sexual intercourse.
Stop using tampons.
Avoid using creams or other vaginal medicines.
Take over-the-counter pain medicines an hour or 2 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.
An instrument called a speculum is inserted into the vagina to hold it open.
A vinegar 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 viewed through the colposcope, which is placed outside the vagina.
If your health care provider sees abnormal areas on the cervix, a biopsy will be done. 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, an instrument 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 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 get dressed.
If a biopsy was done, you may have mild cramping or light bleeding for a few days. You may also have discharge from the medicine used to stop bleeding at the biopsy site.
Use pads, not tampons, for at least the first 24 hours.
If you have any discomfort, over-the-counter pain medicine can provide relief.
Ask your health care provider when you can resume sexual intercourse.
If a biopsy was done, your health care provider will get the lab report in a week or 2. You and your health care provider can then discuss the results. In some cases, you may be scheduled for further tests or treatment. Be sure to keep follow-up appointments with your health care provider.
Call your health care provider if you have:
Heavy vaginal bleeding (more than a pad an hour for 2 hours).
Severe or increasing pelvic pain.
A fever over 100.4°F (38°C)
Foul-smelling or unusual vaginal discharge.
