Cervical diseases are common and frequent among women, among which cervical cancer is one of the most common malignant tumors, with the second highest incidence rate among female tumors, and approximately 200,000 women die from this disease each year worldwide. In developed countries, the incidence of cervical cancer has declined significantly, due in large part to early diagnosis and treatment of precancerous lesions. In developing countries, the incidence of cervical cancer is six times higher than in developed countries because cervical screening is not yet well established. What should be particularly alarming is that due to environmental pollution and poor living hygiene habits, cervical cancer, which was originally more frequent in women around the age of 50, has now targeted young women. According to the screening results of tens of thousands of cervical lesion patients at Beijing Friendship Hospital, 607 cases of abnormalities were found, and 345 cases of cervical precancerous lesions and 9 cases of cervical cancer were finally diagnosed. The youngest cervical precancerous lesion is 23 years old, and the age distribution of cervical cancer patients is 34-48 years old, among which 33.3% are under 40 years old and 66.6% are between 40 and 48 years old, cervical cancer has seriously threatened the health and life of young and middle-aged women. Clinical follow-up shows that it takes about 10 years to develop from general cervical precancerous lesions to cervical cancer. From this perspective, cervical cancer is not terrible, it is a preventable and curable disease. The key to prevention and treatment is regular gynecological examination, timely detection and treatment of cervical precancerous lesions to stop their development to cervical cancer. If these preventive and curative measures can be implemented, the cure rate of cervical cancer is very high. There are various treatment methods for cervical lesions. Depending on the degree of lesions, age and fertility requirements, doctors can treat patients with medication and surgery. For mild to moderate cervical precancerous lesions, high-frequency electric knife cervical circumcision is very effective, with no hospitalization, little pain and low cost. For cervical cancer, hysterectomy and chemotherapy can be performed. To prevent cervical cancer, we should do the following: 1. Strengthen health education and raise awareness of prevention. 2. 2. Pay attention to menstrual hygiene, avoid premature sexual life and eliminate sexual confusion. 3.Gynecological examination should be done regularly, and married women should have cervical smear once a year. If problems are found, further pathological histological examination must be done to determine the nature of the lesion and timely treatment. 4. For cervical lesions and reproductive system infections that have been detected, it is important to be vigilant and take appropriate treatment measures actively. In order to prevent the occurrence and development of cervical cancer.
