What are the causes of cervical erosion?
The cervix is one of the important tissues and organs in the female reproductive system. From embryo and female fetus to old age, the cervix involves issues such as gynecology, obstetrics, family planning, women's health care and reproductive health throughout a woman's life. It is the guarantee for women's physical health and family happiness. However, cervical diseases nowadays seriously affect women's physical and living health, and cervical erosion is one of them.
So, what is cervical erosion?
Gynecological experts introduced: Cervical erosion is not an independent disease but a form of chronic other cervical inflammation. Severe cervical erosion does not actually belong to real erosion. When the squamous-columnar junction migrates outward and the cervical os is covered by another type of epithelial tissue, due to the thinness of the covering new epithelium, it is even possible to see the blood vessels and red tissues underneath, which makes it look like real erosion, so it is called cervical erosion. Cervical erosion is one of the common gynecological diseases that can severely affect women's physical and living health.
What are the causes of cervical erosion?
Experts introduced: Cervical erosion is a form of chronic cervicitis, including congenital erosion, acquired erosion, and inflammatory erosion. Different types of erosion have different causes.
[1] Congenital erosion
Congenital erosion refers to the situation where the female fetus's reproductive system development is influenced by maternal sex hormones, leading to the migration of the squamous-columnar junction outward, with the cervical os covered by columnar epithelium. Normally, the erosion present at birth only lasts for a short period of time and gradually resolves naturally when the level of estrogen from the mother decreases. However, there are also individual patients whose erosion persists for a long time. The state of the congenital erosion cervix is often normal or slightly larger, not very neat, and the cervical os is mostly cracked.
[2] Acquired erosion
Acquired erosion refers to the erosion caused by the proliferation of the endocervical canal mucosal columnar epithelium towards the vagina beyond the cervical os, which only occurs during pregnancy when ovarian function is vigorous. Postpartum, it can resolve spontaneously. Although patients report increased leukorrhea, it is clear mucus. Pathological examination shows no inflammatory cell infiltration under the columnar epithelium, only a few lymphocytes. The cervix of acquired erosion is often larger, with the cervical os being normal, transverse fissure, or irregular rupture. The boundary around the eroded area is clear compared to the normal cervical epithelium, and sometimes a boundary line presenting as an indented groove can be seen. Some erosions may show capillaries on the surface, with local chronic congestion.
[3] Inflammatory erosion
Inflammatory erosion is the most common pathological change in chronic cervicitis. The squamous epithelium of the cervical vagina is replaced by the columnar epithelium of the cervical canal, and its appearance is red. Therefore, it is not true erosion but rather pseudo-erosion. Under light microscopy, multinucleated white cells and lymphocyte infiltration can be seen in the submucosa, along with small round cells and plasma cell infiltration in the interstitium. The superficial layer of the submucosal tissue is the main site of inflammatory cell infiltration, with fibrous tissue hyperplasia of the cervix. The cervical canal mucosa also proliferates, protruding outside the cervical os to form polyps.
LEEP Knife - Easily "eliminates" cervical erosion and restores women's health
The LEEP knife technology uses ultra-high frequency radio wave technology with an intelligent self-control system, integrating lesion removal, hemostasis, and ablation using ultra-high frequency radio waves. The American LEEP knife treatment technology can penetrate the surface tissue to reach a specific depth, precisely focusing on the inflamed area, causing the diseased tissue to coagulate, degenerate, and necrose without damaging normal cervical tissue. During the treatment process, it has many advantages such as safety, painlessness, minimally invasive, and walk-in/walk-out treatment. It can efficiently treat moderate to severe cervical erosion, cervical intraepithelial neoplasia, and early carcinoma in situ in one session. It is the preferred choice for patients with severe cervical diseases.
