Cervical erosion is a very common sign in women and how it is treated depends on the following: 1. First, a cervical cytology test (TCT) is done to rule out cervical cancer or precancerous lesions. If available, it is best to do HPV testing at the same time. 2. For patients with cervical erosion who have symptoms (increased leucorrhea, bleeding after intercourse, etc.), if the TCT report is cervicitis and there is no cervical cancer or precancerous lesions, you can first choose to apply local medication; if the effect is not good, you can treat with physical methods, such as laser, microwave, etc. As far as possible, infertile women choose treatments that are less traumatic to the cervix. 3. Some patients have cervical erosion but no symptoms, TCT reports no cervical cancer or precancerous lesions, or high-risk HPV negative, can be treated without treatment, and annual cervical cytology examination is sufficient. 4. Some patients with increased leucorrhea for a long time should also consider whether they have vaginal inflammation, special pathogens (chlamydia, etc.) infection, and may also be related to intrauterine devices.
