Some women who suffer from cervical erosion and use laser, freezing or electrotherapy for cervical erosion repair surgery can cause the following hazards: 1. After surgery, it is easy to cause cervical canal stenosis or cervical adhesions, resulting in poor flow of menstrual blood during menstruation in the future, or even not easy to flow out of the uterine cavity causing stagnation of menstrual blood, dysmenorrhea and uterine cavity infection. 2. The cervical scars will harden the cervical canal, which will easily affect the passage of sperm and affect pregnancy. After the surgery, women who are pregnant in the future are likely to have a difficult delivery when they deliver the baby. After the cervical erosion repair surgery, you need to follow the doctor’s instructions to have regular checkups to confirm whether there is scarring or adhesions on the cervix, and cooperate with the doctor to dilate the cervix after the diagnosis.
