Firstly, there are many causes of cervical erosion, some of which are due to congenital factors. Many diseases can also cause cervical erosion, as well as multiple induced abortions. Nowadays, many young women engage in premarital sex and, not wanting children temporarily, end up having multiple induced abortions, which is a major cause of cervical erosion. Other factors include having sex too early and having too many sexual partners. If you do not want children, it is essential to take proper contraceptive measures to avoid harming your body. It is always important to maintain good hygiene habits and pay attention to hygiene before and after intercourse.

Symptoms of cervical erosion

Most patients with cervical erosion do not exhibit symptoms. Those with symptoms largely display an increased amount of vaginal discharge, which is mucopurulent. Vaginal secretion can stimulate itching and burning sensation in the vulva. Additionally, symptoms may include bleeding outside of menstruation periods and post-coital bleeding. If combined with a urinary tract infection, symptoms can include urgency to urinate, frequent urination, and painful urination. Gynecological examination may reveal congestion and edema of the cervix, mucosal eversion, and mucopurulent secretions attached or even flowing out of the cervical canal. The cervical canal mucosa is fragile and prone to bleeding. If infected with Neisseria gonorrhoeae, due to the involvement of paraurethral and vestibular glands, congestion and edema of the urethral and vaginal openings may be observed, along with a copious amount of purulent discharge.

What should I do about cervical erosion?

Cervical erosion is not considered a disease. Simple cervical erosion is merely a physiological condition in young women. If cervical erosion is present, there is no need for special treatment, but it is routine to first perform screening for precancerous cervical lesions. The key is to check for any precancerous lesions or cervical cancer, and also to examine the condition of secretions. If the secretions are normal and there are no symptoms of inflammation, then it’s not a concern, and there is no need for any medication, various physical treatments, or even surgical treatments aimed at the cervical erosion; continuing regular physical examinations in the future will suffice.

Can cervical erosion be treated with the nine-valent vaccine?

Whether to get the nine-valent cervical cancer vaccine is unrelated to cervical erosion. The nine-valent cervical cancer vaccine is generally suitable for individuals under the age of 25. Those who are not within this age range cannot receive the nine-valent vaccine. Patients with cervical erosion should first go to the hospital for cervical cancer screening, typically involving a TCT and HPV test. TCT, also known as ThinPrep cytologic test, and HPV, known as the human papillomavirus, are used to preliminarily screen for cervical cancer and precancerous lesions. Therefore, patients with cervical erosion can receive the nine-valent vaccine as long as the cervical cancer screening shows no issues and they are under the age of 25.

Is electrocauterization good for cervical erosion?

Cervical erosion electrocautery is a treatment method used in the past. Nowadays, most cases can generally be treated through physical methods like laser, electrocoagulation, and cryocondensation. After electrocautery, the cervical tissue typically becomes harder, which can result in cervical lacerations during childbirth for patients who plan to conceive in the future. Therefore, electrocautery is rarely used now, and most treatments currently employ laser or electrocoagulation methods. Patients with cervical erosion should first visit a hospital for cervical cancer screening, which generally involves TCT and HPV testing. If these tests show no cervical cancer or precancerous lesions, simple cervical erosion is generally not a serious issue. At this time, topical medications or some physiotherapy treatments can also be used for symptomatic treatment. (Please undergo medication under the guidance of a professional doctor, and do not medicate blindly.)

Moderate cervical erosion is what?

Cervical erosion can be classified into mild, moderate, and severe based on the size of the erosion area. Mild erosion occurs when the erosion area is less than 1/3 of the cervical area, and moderate erosion when the area is between 1/3 and 2/3. Severe erosion occurs when the area exceeds 2/3 of the cervical area. Women with moderate cervical erosion often suffer from infertility and miscarriages. More seriously, if moderate cervical erosion is left untreated or persists without healing, it can develop into severe cervical erosion or precancerous lesions, and even cervical cancer. Moderate cervical erosion can affect future normal fertility, so it is crucial to take the disease seriously and undertake preventive measures.
