It is not a disease, but a manifestation of the migration of cervical columnar epithelium.Its main content structure includes:Definition and essence(physiological changes),Common triggers(Hormonal changes, etc.),Difference from disease(need to be wary of co-infection),Inspection and handling principles(Regular screening is the main thing).The key point is to clarify its non-pathological characteristics and avoid over-treatment.

1. The nature of cervical erosion

Cervical erosion is actuallyIntracervical columnar epithelial eversionAs for the appearance of the vagina, because the columnar epithelium is thin and appears red and granular, it was mistakenly called "erosion" in the past.Modern medicine has made it clear that this isPhysiological phenomena under the action of estrogen, common in adolescent and pregnant women.The International Federation of Gynecology and Obstetrics (FIGO) has renamed it "cervical columnar ectopia".

regularCervical TCT+HPV combined screeningis the key, no special treatment is needed for asymptomatic people.Domestic "Obstetrics and Gynecology" guidelines point out that symptomatic treatment is required only when combined with infection, such as:

situation	Processing method
HPV positive	Regular follow-up
bacterial vaginosis	Metronidazole and other drug treatments

Physical therapy (such as laser) is only suitable in rare cases of recurrent bleeding.

4. Cognitive Misunderstandings and Summary

In the past, cervical erosion was mistakenly associated with cervical cancer, leading to overtreatment.In fact itsThe risk of cancer is the same as that of a normal cervix, the emphasis is on regular screening.Academician Lang Jinghe of Peking Union Medical College Hospital emphasized: "The core of cervical health isStandardized screeningRather than blindly treating appearance changes." It is recommended that women over the age of 21 undergo a TCT examination every 3 years, and women over the age of 30 combined with HPV testing.
