What is cervical precancerous lesions?

Cervical precancerous lesions (CIN) are pathological conditions of abnormal proliferation of cervical epithelial cells. They are usually detected through cervical screening. Early intervention can effectively prevent cervical cancer. Treatment includes surgical resection, drug therapy and regular follow-up. The specific method should be selected according to the severity of the lesion.

1. The causes of cervical precancerous lesions CIN mainly include human papillomavirus (HPV) infection, genetic factors, environmental factors and a weak immune system. HPV infection is the main cause, especially high-risk HPV16 and 18. Genetic factors may increase an individual's susceptibility to HPV infection. Environmental factors such as smoking, long-term use of oral contraceptives and multiple sexual partners can also increase the risk. A weak immune system, such as HIV infection or long-term use of immunosuppressants, may lead to progression of the lesion.

2. The treatment methods for cervical precancerous lesions CIN are divided into CIN1, CIN2 and CIN3 according to the severity of the lesions. CIN1 usually does not require special treatment and regular follow-up is sufficient. CIN2 and CIN3 require active treatment, and common methods include cryotherapy, laser therapy and cervical conization. Cryotherapy destroys abnormal cells through low temperatures and is suitable for CIN1 and CIN2. Laser therapy uses high-energy laser beams to accurately remove diseased tissue and is suitable for CIN2 and CIN3. Cervical conization surgically removes part of the cervical tissue and is suitable for CIN3 or suspected cancer.

3. Preventive measures for cervical precancerous lesions (CIN) include HPV vaccination, regular cervical screening and improved lifestyle habits. HPV vaccine can effectively prevent high-risk HPV infection and is recommended for women of appropriate age. Regular cervical screening includes cervical cytology and HPV testing to detect lesions early. Improving lifestyle habits such as quitting smoking, reducing the number of sexual partners and using condoms can reduce the risk of infection.

Cervical precancerous lesions (CIN) are the early stages of cervical cancer. Early detection and active treatment can effectively prevent the occurrence of cervical cancer. Women are advised to undergo regular cervical screening, get HPV vaccines, and maintain a healthy lifestyle to reduce the risk of disease.
