If screening shows that you have abnormal cells in your cervix, the doctor or nurse you see in the colposcopy clinic (colposcopist) may recommend that you have them treated. The aim of treatment is to remove or destroy the abnormal cells in your cervix. However, the first step is to be sent for a colposcopy. Treatment can be offered at a first visit to Colposcopy. If this is a possibility you will be advised beforehand.

Types of treatment for cervical abnormalities

The treatment you will be offered depends on the type of abnormal cells you have in your cervix (the grade of CIN and/or the presence of CGIN) and how advanced the changes are. Your colposcopist will advise you on the specific treatment you will require during your colposcopy appointment. CIN1 is usually not treated as these changes often return to normal given time and are not precancerous.

Large loop excision of the transformation zone (LLETZ)

Also known as LEEP or diathermy loop biopsy or just a loop, this procedure uses a small wire loop and an electrical current to cut away the affected area of tissue and seal the wound at the same time. The advantage of this treatment is that the cells are removed rather than destroyed, so the tissue can be sent for further tests to confirm the extent of the cell changes and make sure the area of your cervix that contains the cells has been removed.

Cone Biopsy

A cone of tissue is cut away from your cervix to remove all the abnormal cells. It allows the doctor to remove a slightly larger part of the cervix than with a loop (LLETZ) biopsy. A cone biopsy allows for the cells at the edges of the specimen to be seen clearly through a microscope ensuring that all of the biopsy can be examined by a histopathologist.

A cone biopsy is usually carried out under a general anaesthetic (very small cone biopsies can be performed under local anaesthetic). A vaginal pack will sometimes be put in place in theatre while you are under anaesthetic. This is like a long bandage that puts pressure on the biopsy site and so helps stop any bleeding (a bit like putting pressure on a cut to stop it bleeding). It will be removed before you go home. It is advisable to have some painkillers at home (such as you would take for period pains) as some women experience a deep ache and/or tenderness in their pelvis. It is not unusual to feel tired for a few days or even a week or so following a general anaesthetic.

Straight wire excision of the transformation zone (SWETZ) or Needlepoint excision of the transformation zone (NETZ ).

Similar to a cone biopsy these procedures remove a piece of tissue but use a straight wire or needle diathermy with electricity to cut and seal the tissue like a LLETZ treatment. The procedures are done in a clinic with local anaesthetic (like a LLETZ) or under general anaesthetic (like a cone biopsy). These treatments are usually done if the abnormal cells are inside the cervical canal or are glandular abnormal cells.

Cryotherapy

A cold probe is used to freeze away the abnormal cells in the cervix. This is sometimes used to treat CIN1.

Laser Treatments

This is sometimes called laser ablation. Lasers pinpoint and destroy abnormal cells in the cervix. If necessary, a laser can also be used to remove a small piece of the cervix itself. This is called laser excision or laser cone biopsy.

Cold Coagulation

Despite the name of this treatment this procedure involves applying a hot probe to the cervix, which, like laser, destroys the abnormal cells.

A local anaesthetic (where the area is numbed but you are still awake) is given before any of the treatments described above. A cone biopsy may require a general anaesthetic (where you are asleep).

Summary

Your colposcopist should provide you with additional information on the treatment that you will be having. Remember to ask if you have questions.

Bleeding (at the time of treatment or in the two to three weeks afterwards) or infection (more often 10-14 days after) can occur after treatment for abnormal cells of the cervix. You may experience vaginal discharge or bleeding like the end of a period for two to three weeks after your treatment. However this does vary a lot, for example a few women will have no bleeding at all and some will be bleeding for up to six weeks. After your treatment you may feel some pain, this is because the local anaesthetic used during your treatment will wear off after two to three hours. This pain often feels like cramps that you can have during your period. Some women notice pain more the day after the treatment. Sometimes periods can be irregular or more painful for two to three months after treatment. Always contact your GP or colposcopist if you are experiencing any problems after treatment. There is no reason to put up with discomfort that can easily be treated.

If you are working you might be advised to take a day or two off from work (your colposcopist will let you know if this is necessary). You might need some pain relief after your treatment, the clinic where you had treatment can advise you on this.

Generally, a single, straightforward treatment to the cervix is very unlikely to adversely affect fertility or the ability to have a normal pregnancy.
