Cervical erosion, i.e. cervical columnar epithelial ectasia, generally does not turn into cervical cancer, but due to individual differences, it is impossible to generalize. Cervical columnar epithelial ectasia is a physiological phenomenon in which the columnar epithelium of the inner cervical canal moves out to the outer cervical canal due to the influence of estrogen level in the body. With the change of estrogen in the body, it can disappear on its own. Patients with second-degree cervical epithelial ectasia usually have no obvious symptoms and do not need to worry too much, and generally will not be transformed into cervical cancer. However, for patients with second degree cervical ectopic combined with HPV infection, there is a certain chance of cervical cancer. It is recommended that patients with HPV infection should actively cooperate with doctors to take treatment measures to treat the primary disease, so as to control the disease and improve the prognosis. In daily life, it is necessary to ensure local cleanliness to avoid secondary infection. Do not engage in high-risk sexual behaviors, fix sexual partners and take reasonable contraceptive measures. Follow the doctor’s instructions for regular checkups to understand your body’s condition.
