Monitoring and evaluation


  • We register almost 10,000 invasive procedures on cervix per year.
  • 66% of invasive procedures are diagnostic (44% are biopsies and excisions and 22% abrasions).
  • 19% are therapeutic procedures, predominantly LLETZ (14%), while proportion of cold knife conisations is decreasing in recent years (from 8% in 2014 to 3% in 2020–2022).
  • 15% are hysterectomies.
  • Among diagnostic procedures, 18% are diagnosed with HSIL+, while this is the case with 66% of therapeutic procedures.
  • Around 90% of women with HSIL+ biopsy have another invasive procedure (mainly therapeutic) preformed in one year period. HSIL+ is detected in almost 90% of follow-up therapeutic procedures.
