The medical term for cervical erosion is 'cervical ectopy'. It is a condition where the cells at the mouth of the
cervix changes from the squamous cells normally found at this region to columnar cells.
Causes of Cervical Erosion:
- Estrogen level: Cervical erosion is believed to be a response to the levels of circulationg oestrogen in the body.
- In Pregnancy: Cervical Erosion is a very common finding during pregnancy - believed to be due to the high levels of estrogen levels in the body at that time.
It can cause mild bleeding during pregnancy, usually during sexual intercourse when the penis touched the cervix.
The erosion disappears spontaneously 3 - 6 months after childbirth.
- In women on birth control pills: All birth control pills contain the hormones, estrogen and progesterone in different strengths. Cervical ersion is more common in women taking pills with a high level of estrogen.
Miscellaneous Causes: It is believed by many that chronic infection of the vagina, vaginal douching and chemical contraceptions like anti-sperm gels can change the normal level of acidity of the vagina and cause cervical erosion. But these theories are yet to be proved.
Signs and Symptoms of Cervical Erosion: Most women with cervical erosion do not have any symptoms. But women with a large area of erosion can suffer from:
Tests for Cervical Erosion: Cervical erosion has to be differentiated from other cervical ulcers caused by carcinoma, syphilis and other sexually transmitted diseases. A cervical biopsy should ideally be carried out.
Treatment of Cervical Erosion: If the cervical erosion has no symptoms but have been discovered on routine eaxamination, treatment is not necessary.
If symptoms are present however, active treatment becomes necessary. The aim of the treatment of cervical erosion is to destroy the columnar cells so that normal squamous cells can grow in their place:
- Electrocautery: The cells are burned off by using heat generated by electric current.
- Diathermy: High temperatures are applied to the area of cervical erosion so that the cells are damaged.
- Cryocautery: Extreme cold generated by the application of nitrous oxide gas is used to destroy the cells.
Infections: Infections should also be controlled by antibiotics.
Post-operative advice: The area of cervical erosion takes 6-8 weeks to heal. So the patient is asked to avoid sex during this period to avoid any injury.
