How to screen for cervical lesions? What are the screening methods for cervical lesions?

With the improvement of people's living standards and changes in the current living environment, more and more diseases are wreaking havoc, such as gynecological diseases that plague our female compatriots. So how should we screen for cervical lesions?

Screening start and stop time

Screening should start for sexually active women aged 21 years and above; 21-29 years old: cytology screening, once every 3 years; 30-65 years old: HPV combined with cytology screening, once every 5 years (preferred), or cytology screening, once every 3 years. Stop screening if you are >65 years old, have no CIN2 or higher lesions in the past 20 years, have 3 consecutive negative cytology results in the past 10 years, or 2 negative cytology combined with HPV screening, and the last screening was within 5 years. Routine screening for CIN2 or higher lesions treated (or spontaneously resolved) in the past 20 years should be continued for at least 20 years, even if over 65 years old.

Three-step screening and diagnosis steps for cervical lesions

The first step: cervical cytology/HPV testing - initial screening

The second step: colposcopy ------------ assisting diagnosis

The third step: histopathological examination---confirmation (gold standard)

Introduction to several screening methods

(I) Thin-layer liquid-based cytology test (TCT)

2. HPV testing

(III) Colposcopy

(IV) Cervical biopsy and endocervical curettage

5. Diagnostic cervical conization

Cervical Intraepithelial Neoplasia Treatment

Patients with CINⅠ who have cytological examination results of LSIL or below can simply undergo follow-up observation. If the lesion progresses during follow-up or persists for 2 years, treatment should be initiated. If the cytological examination shows HSIL, treatment should be given. If the colposcopy examination is satisfactory, freezing or laser treatment can be used. If the colposcopy examination is unsatisfactory or ECC is positive, cervical conization is recommended. CINⅡ should be treated with methods such as cryosurgery, laser, LEEP, etc. These methods each have their own advantages and disadvantages, but there is no significant difference in effectiveness. CIN III should undergo cone biopsy, which can also exclude invasive cancer. Older women who do not want to have children can also undergo total hysterectomy, but invasive cancer must be excluded.
