Colposcope

'A doctor looking down a colposcope'

What is colposcopy?

Colposcopy ('coll-poss-co-pee') involves looking at your cervix and the vagina with a colposcope, which is a magnifying instrument. Often, women are sent an appointment to attend the Colposcopy Clinic after a routine smear test.

Where is the NHS colposcopy clinic for Cambridge?

The colposcopy clinic for the Cambridge area is held at the Rosie Hospital Outpatient Clinic, on the Addenbrooke's Hospital site.

Where can I get more information?

When you are sent your colposcopy appointment, you will also be sent a booklet giving more information. This includes a phone number, so that you can if you wish speak to the colposcopy nurse and ask her any questions before you attend the clinic.

Why do I need to go to the colposcopy clinic?

There are several reasons why women are invited for an appointment at the colsposcopy clinic - all of them include needing to look carefully at your vagina and/or cervix:

  • Three 'inadequate' smears
    You might be invited to attend the Clinic if three attempts to take a smear test have failed to provide a good enough cell sample for the laboratory. Because of the additional equipment at the Colposcopy Clinic, they have a better chance of either getting a good-quality smear, or of using an alternative technique to examine your cervix.

  • Abnormal smear
    You might be invited to attend the Clinic if a smear test has shown some abnormalities of the cells. These smears need further investigation because it is known that if they are not treated some of these abnormal smears might progress to cervical cancer in time.

What happens during the colposcopy examination?

At the Colposcopy Clinic we will explain to you what we would like to do.

  • As for a smear test, you will need to remove your shoes and pants.

  • For your comfort, you will lie on your back on a special couch with your legs supported.

  • The examination itself takes about ten minutes and is similar to having a smear test but using some additional equipment. The doctor (or nurse) will pass a speculum into your vagina so they can get a good view of your cervix. The colposcope itself does not go inside you, it just gives a better view of your cervix. If you wish, you can watch the procedure on a TV screen next to the couch.

  • Smear test: A sample of cells can be taken, as for a smear test - if this is the reason for the appointment.

  • Infection: If necessary, swabs can be taken to detect any infection on the cervix.

  • Biopsy: A solution of mild acetic acid (like vinegar) is gently washed over the cervix. This makes any areas that have abnormal cells appear white. The colposcopist can then take a tiny sample (a biopsy), which will be sent to the laboratory for further testing.

What will happen after the examination?

After the examination, the colposcopist will explain what they have seen and whether or not they think you will require any further treatment at this appointment or later on.

Will I need further appointments?

Whether you will need further appointments depends on what is found during the examination and from any biopsies taken. You might be invited to make an appointment for further treatment at this stage, or an appointment might be sent to you when the result of the biopsy has been received. Usually, the results are ready in about 4 to 6 weeks. Sometimes, treatment is offered at your first visit.
