ENCervical dysplasia is not cancer but a change in surface cells of the cervix that may clear up, persist or, over years, turn into cancer. Its grade (CIN, LSIL or HSIL) decides whether doctors watch or remove it; a tumour needs cervical cancer treatment instead.
Below: how the diagnosis is confirmed in Germany, when watching is chosen, how surgery works, what follows and what to collect before writing to a German department.
What the letters in the report mean
The number after CIN shows how deeply the cervical lining is affected, not the size of the area: CIN 1 (mild) is confined to the lower third, CIN 2 (moderate) reaches two thirds, CIN 3 (severe) involves more or all of it. LSIL (low grade) equals CIN 1; HSIL (high grade) covers CIN 2 and 3. German specialists recommend giving both.
Dysplasia is usually caused by high-risk human papillomavirus (HPV) types. The immune system usually clears HPV within a year or two; cells change when infection lasts for years, so what counts is finding the same type again, not one positive test. See the WHO fact sheet on HPV and cancer and the page on HPV treatment in Germany.
For borderline or unclear smears, German laboratories can add dual staining for the proteins p16 and Ki-67. It shows whether the virus is interfering with cell division, separating a worrying change from a passing one: a positive result leads to colposcopy, a negative one usually to a later recheck.
How the diagnosis is confirmed in Germany
The diagnosis is confirmed at a dysplasia clinic (Dysplasie-Sprechstunde), a dedicated appointment in gynaecology departments that follows a common algorithm of the German screening programme. One visit usually covers the examination, cytology, an HPV test, colposcopy and, if needed, a biopsy.
Colposcopy means examining the cervix through a lit magnifier after dabbing it with diluted acetic acid and iodine. Doctors look twice at areas turning sharply white or showing coarse vessels, and at areas iodine leaves pale instead of brown; the targeted biopsy comes from exactly there, so the most altered cells are examined.
German departments often request slides or paraffin blocks of earlier biopsies and review them: the grade decides treatment, and pathologists often disagree about CIN 2. Likewise, a report saying only «dysplasia», without a grade or HPV result, is incomplete.
When it is watched and when it is treated
In Germany, cervical dysplasia is treated when changes are severe or persistent; a low grade (CIN 1) is usually watched, as many such changes clear up on their own. Watching is a schedule, not inaction: a repeat check with colposcopy, smear and HPV test, usually after six months, sometimes after a year. Young women with fully visible CIN 2 are often watched too.
Treatment is needed for CIN 3, persistent CIN 2, disagreement between cytology and biopsy, or a lesion edge hidden in the cervical canal. The usual method is loop conisation (LEEP or LLETZ): a thin electrical loop removes a small cone of tissue under local or brief general anaesthesia, usually within half an hour. Tissue always goes to pathology.
Women most often fear for a future pregnancy. Honestly, the amount removed matters: a 2017 Cochrane review found complications, above all premature birth, rise with cone depth. Doctors therefore remove the changes with a small margin, no more, and weigh plans for children, as the German S3 guideline on the prevention of cervical cancer advises; its latest version has expired, with no successor yet.
After treatment: follow-up, HPV and vaccination
Follow-up after conisation is not optional: a smear and an HPV test are usually done after six months, one year and two years. Dysplasia does not hurt, so feeling well proves nothing; a negative HPV test says much more, as dysplasia then returns in only a few women, even with unclear cone edges. Normal results mean returning to routine cervical cancer screening.
The HPV vaccine does not treat existing infection. Germany’s Standing Committee on Vaccination (STIKO) recommends it at ages 9 to 14, with catch-up before the 18th birthday; after treatment, adults decide with their doctor, as a 2025 Cochrane review found vaccination around conisation may lower recurrence, on weak evidence. Examples, not a ranking: in Frankfurt, Professor Marc Thill heads gynaecology and gynaecological oncology at AGAPLESION MARKUS KRANKENHAUS, whose focus includes dysplasia and endometriosis (see AGAPLESION hospitals in Frankfurt). In Munich, Professor Martin Pölcher is a chief physician of gynaecology at Rotkreuzklinikum, heads its gynaecological cancer centre and specialises in minimally invasive surgery.

What to collect before you write
Gather the dated cytology report, the HPV result naming the type, the colposcopy record, the biopsy histology with slides or blocks, reports of earlier cervical surgery, and details of pregnancies and plans for them.
A written assessment of the documents comes first, then a face-to-face appointment with colposcopy, and only then the decision to watch or treat. Without histology, any written assessment stays preliminary.
Frequently asked questions
How long does treatment for cervical dysplasia take in Germany?
It usually takes a few short visits, not a long hospital stay. Colposcopy with biopsy takes one appointment; histology follows within a few days. Conisation is often an outpatient procedure, sometimes with one night in hospital; women should take it easy for about a week afterwards. The clinic’s reply states the number of visits.
Can I get pregnant after conisation?
Yes. Most women become pregnant and carry a baby after conisation, even after a repeated one. Each shortening of the cervix raises the risk of premature birth, though, so mention the conisation at your first pregnancy appointment. Dysplasia that cleared up on its own is no obstacle to pregnancy.
What happens if dysplasia is found during pregnancy?
Usually it is watched and treated after the birth. Colposcopy and, if needed, a biopsy follow the same rules as outside pregnancy and do not endanger it. If cancer has been ruled out, even severe dysplasia is not operated on but checked about every three months, then reassessed after the birth.
How AlenMed organises treatment
After you get in touch, a medical translator prepares your documents for the relevant departments, whose reply states the proposal and the number of visits; medical visa papers are prepared in parallel.
AlenMed has 86 partner hospitals in 38 cities and 345 doctors, with its office in Munich. A coordinator books appointments, interprets at consultations and makes sure the follow-up visit is scheduled before departure.
This material is for information only and is not an offer; the treatment plan is decided by a doctor at a face-to-face appointment.
