How long does it take for cervical erosion to develop into cervical cancer?

1. Cervical erosion generally refers to cervical columnar epithelial ectopia. It is generally unclear how long it takes for cervical columnar epithelial ectopia to develop into cervical cancer.

2. The cervical epithelium is composed of cervicovaginal squamous epithelium and endocervical columnar epithelium. The junction of the two is at the external cervical os, called the squamous-columnar junction or squamous-columnar junction. However, this junction area is constant and will be affected by estrogen. If the estrogen level is high, the columnar epithelium can expand outward and occupy the cervicovaginal part.

3. Cervical columnar epithelial ectopia was formerly called cervical erosion, mainly because the columnar epithelium is very thin, and the capillaries in the lower stroma appear faintly and are red, so it looks like erosion to the naked eye. But in fact, cervical columnar epithelial ectopia is a normal physiological phenomenon, which refers to the movement of the columnar epithelium inside the cervical canal outward due to the action of estrogen.

4. Patients usually have no obvious symptoms, and only have symptoms under infection or other stimulation, such as abnormal vaginal discharge, lower abdominal pain, bleeding after sexual contact, etc. It is generally unclear how long it takes for cervical columnar epithelial ectopia to cervical cancer.
