If a colposcopy finds abnormal cells in your cervix, treatment to remove these cells may be recommended.

There's sometimesa risk these cells could become cancerous if left untreated. Removing them means they won't be able to turn into cancer.

The aim of treatment is toremove the abnormal cells while minimising damage to healthy tissue. Usuallyan area about the size of a fingertip is removed.

When treatment is carried out

Treatment to remove abnormal cells from your cervix can be done at the same time as a colposcopyif it'sobvious that some of the cells in your cervix are abnormal.

But sometimes treatment can't be done on the same day.

For example, you may need to wait until you get your biopsy result a few weeks later if it's not immediately clear whether you have abnormal cells in your cervix.

Types of treatment

There are several ways abnormal cells can be removed from the cervix. Some of the main treatments are outlined below.


The most common treatment islarge loop excision of the transformation zone (LLETZ). It:

  • involves removing the abnormal cells using athin wire loop that's heated with an electric current
  • can be carried out at the same time as a colposcopy
  • is usually done while you're awake Local anaesthetic is injected intoyour cervix to numb it during the treatment
  • doesn't usuallyneed an overnight stay in hospital

LLETZ is also calledloop diathermy, loop cone, loop biopsy or loop excision.

Cone biopsy

A cone biopsy isdone less often than LLETZ. It:

  • is a minor operation to cut out a cone-shaped piece of tissue containing the abnormal cells
  • only tends to be used ifa large area of tissue needs to be removed
  • can't be done at the same time as a colposcopy
  • is usually done under general anaesthetic (where you're asleep)
  • may require an overnight stay in hospital

Other treatments

Abnormal cells in the cervix can also be treated with:

  • cryotherapy the abnormal cells are frozen and destroyed (this is only used to treat minor cell changes)
  • laser treatment alaseris usedto pinpoint and destroy abnormal cells on your cervix
  • cold coagulation a heat source is applied to the cervix to burn away the abnormal cells
  • hysterectomy (removal of the womb) this will only be considered if abnormal cells on your cervix have been found more than once, if they're severely abnormal, you're past childbearing age, or you don't want to have more children

After treatment

You can often go home to rest soon after the treatment is finished. Most women feel well enough to return to work and most normal activities the next day.

You'llusually be advised to avoid:

  • driving for at least 24 hours if you had a general anaesthetic you can drive straight away if a local anaesthetic was used
  • using tampons for four weeks (use sanitary pads instead)
  • having sex for four weeks
  • exercising, including swimming,for at least two weeks, or while there's still any bleeding or discharge

You'll also be advised to have another cervical screening test six months after treatment, to check for abnormal cells andthe human papilloma virus (HPV) .

If HPV isn't found, you won't need to be screened again for another three years. But if HPV or significant cell changes are found, you'll be referred for another colposcopy.

Risks and side effects

Common side effects of treatment include:

  • mild pain,similar to period pain this should pass in a few hours and can be relieved with paracetamol or ibuprofen
  • light vaginal bleedingand brown, watery vaginal discharge this may lastup to four weeks

There's also a small risk of more serious complications, such as:

  • an infection this can causeheavy or persistent bleeding,smelly vaginal discharge andpersistent tummy pain ; see your GP if you have these symptoms
  • a slightly increased risk of premature birth (before the 37th week of pregnancy) in future pregnancies this is more likely if you need repeated treatments or a lot of tissue needs to be removed

In most cases, the benefit of treatment will outweigh these risks. Talk to your doctor or nurse if you have any concerns or would like to know more about the potential risks of treatment.
