Cervical erosion is actually a physiological phenomenon and is not alarming. It is caused by the increased levels of estrogen in the body, which causes the columnar epithelium inside the cervical canal to descend and evert. During gynecological examinations, this part of the cervical canal appears red and granular, like eroded protrusions, as if it has decayed. However, this is not the case. When the estrogen levels in a woman's body decrease, this tissue will retract back into the cervical canal and will no longer be visible. In most cases, treatment is not necessary. Treatment is only required if the erosion is combined with an infection, or if there is bleeding after intercourse, or if there is an increase in thick, sticky vaginal discharge that affects sperm passage. Additionally, some women may have cervical cancerous changes that also appear as erosive growths. Therefore, when a woman notices cervical erosion, it is advisable to undergo a TCT screening to rule out the possibility of cervical intraepithelial neoplasia and precancerous lesions of the cervix.
