Cryotherapy
Cryotherapy removes targeted tissue on the cervix by freezing it to a very low temperature. It is a short outpatient procedure that generally requires no anaesthetic.
When it is considered
- Persistent, symptomatic cervical ectropion
- Recurrent bleeding after intercourse
- Biopsy-confirmed low-grade cell changes
- Persistent discharge that has not responded to treatment
How it is carried out
A metal probe is placed against the cervix and gas passing through it freezes the tissue. Treatment is usually given in two cycles and takes a few minutes in total.
You may feel cramping similar to period pain and a sensation of warmth. No rest period is needed afterwards; normal activity resumes the same day.
What to expect afterwards
- A heavy, watery discharge lasting 2 to 4 weeks is expected
- Avoid intercourse, tampons, swimming pools and the sea during this time
- A follow-up examination is arranged once healing is complete
- Seek advice without delay for fever, offensive discharge or heavy bleeding
Its limits
Cryotherapy is not suitable in every case. Where high-grade cell changes are present, tissue-removing methods such as LEEP are preferred so that the whole specimen can be examined. The choice is made together with the biopsy result and the colposcopy findings.
