Is grade 3 cervical lesion cancer?

Some female friends were diagnosed with cervical erosion a few years ago, but they have not received treatment for many years. However, after a period of time, there will be symptoms of abdominal pain and blood clots in the vagina, which is a sign of cervical precancerous disease. So, what is the reason for cervical puncture biopsy of precancerous lesions? What is the reason for the detection of grade 3 precancerous lesions in cervical puncture biopsy? Next, let me learn about the relevant professional knowledge with me.

What is the cause of grade 3 cervical precancerous lesions?

Grade three precancerous lesions only mean that there is a possibility of further aggravation and deterioration, but it does not necessarily mean that deterioration will occur. Moreover, there are no tumor cells at present. In other words, it is still a benign disease, while cervical cancer is a malignant tumor, which may cause migration and external spread, seriously endangering life. However, if precancerous lesions are detected, they need to be treated, because they may worsen due to repeated stimulation, and cervical conization can be performed.

What are the causes of cervical precancerous lesions?

The precancerous lesions of cervical cancer are also called cervical intraepithelial neoplasia (commonly known as CIN). The cervix is ​​located below the uterus and at the top of the vagina and is divided into the external cervical os and the cervical canal. The surface of the external os of the cervix is ​​covered with a layer of squamous epithelium, and the surface of the endocervical canal is covered with a layer of glandular epithelial cells. The area where the squamous epithelium and glandular epithelium meet is where cervical cancer and precancerous lesions are most common.

When the junction of the squamous epithelium and glandular epithelium is affected by carcinogenic factors, changes such as disordered arrangement and abnormal shape of the squamous epithelial cells may occur. According to the degree of these changes, CIN is divided into 3 grades: Grade CIN1 is equivalent to mild intestinal metaplasia of the cervix, Grade CIN2 is equivalent to mild to moderate intestinal metaplasia of the cervix, and Grade CIN3 is equivalent to moderate to severe intestinal metaplasia of the cervix and cervical carcinoma in situ. The higher the level, the more serious the disease. CIN is not equal to cervical cancer, it is not easy to migrate, and the cure rate is basically 100%.

Treatment of cervical cancer

For patients with cervical cancer, timely treatment is very important. A more effective treatment for cervical cancer is microbial immunotherapy, which is the most complete and widely used tumor biological treatment technology at present, and can directly destroy tumor cells. Moreover, the therapeutic effect is more prominent when used in conjunction with traditional treatment methods. It is the fourth major new cancer prevention technology after surgery, radiotherapy and chemotherapy.
