Cervical cryotherapy

What is cervical cryotherapy and when is it necessary?

Cervical cryotherapy is an intervention done with a freezing technique, during which abnormal tissues in the cervix freeze, followed by tissue death.

Development of cervical cancer

Cervical cancer is usually caused by certain types of HPV (human papilloma virus) that enter the body through sexual contact. Of the more than a hundred known types, we distinguish between low-risk (LR) and high-risk (HR) viruses.

Viruses 16, 18, 31, 33, 35, 45, and the high-risk 52 may play a significant role in the development of cervical cancer. Its prevalence is proven by the fact that nearly 80 percent of women become infected with certain types of the virus during their lifetime.

With the help of a properly functioning immune system, the body defeats the virus within 1-2 years, but for the prevention of cervical cancer, it is very important to participate in regular (annual) gynaecological screening (cytological smear test) from the beginning of active sexual life, HPV standardization (detection at the DNA level) and then half-yearly screening if high-risk virus or viruses were detected during standardization. We can effectively protect against the disease that develops over several years with regular cervical screenings, as the cell changes detected in time can be treated with complete success.

Prevention of cervical cancer

  • HPV vaccination
  • Avoidance of frequently changing partners, monogamy
  • Responsible sex (using a condom does not provide complete protection either because the virus can spread through contact with intimate skin surfaces)
  • Regular cervical screening

Indications and meanings of precancerous conditions of the cervix

Precancerous condition: CIN (cervical intraepithelial neoplasia), i.e. cervical dysplasia, which means the abnormal development of cells.

  • CIN I: mild dysplasia, may heal spontaneously
  • CIN II: moderate dysplasia with cell changes in two-thirds of the cervical mucosa
  • CIN III: severe dysplasia, an abnormal lesion of more than two-thirds of the cervical mucosa.

How does cryotherapy work?

Freezing treatment of the cervix takes only a few minutes. The vagina is exposed using a so-called colposcope and the cervix is ​​brought into view.

A head shaped according to the shape of the cervix is ​​placed on the surface to be treated and then the area is frozen.

The intervention takes place within the framework of outpatient care, so the patient can leave the hospital shortly after the cryotherapy procedure and start working the next day.

What complications can occur?

There are no significant complications of the painless and fast procedure.

However, after the procedure, there is a coloured flow for 3-4 weeks, which is the result of the rejection of the dead tissue.

The duration of complete healing (new epithelial formation) is 4 weeks, until then sexual intercourse and sitting bath should be avoided.
