Our population is large and the incidence of cervical cancer is six times higher than that of developed countries. Studies have shown that the etiology of cervical cancer is closely related to the persistent infection of HPV high-risk subtypes, and it is a preventable disease that takes about 5-10 years to develop from precancerous lesions to invasive cancer, so it is completely possible for early detection, early diagnosis and early treatment. The normal population in Beijing is 26.13% infected with high-risk HPV. Cervical lesion is one of the most common disorders in women, and its most serious case is the development of cervical cancer. Cervical cancer is one of the common malignant tumors in gynecology, with the second highest incidence of malignant tumors in women, after breast cancer, but the first in some developing countries. The World Health Organization reports that there are about 500,000 new cases worldwide each year, and the country with the highest incidence of cervical cancer is Chile (15.4/100,000), followed by China and Japan with the lowest (2.4/100,000), accounting for 73%-93% of the incidence of malignant tumors of the female reproductive system. The significant decrease in its incidence in developed countries is largely attributed to the effective prevention and early diagnosis and treatment of cervical cancer. Although cervical erosion is a physiological change that does not require treatment, screening for cervical disease is again advantageous in terms of screening for diseases of the female reproductive system, which can be seen superficially by gynecological examination, as well as pathological tests on its exfoliated cells, and the use of colposcopy, which allows for magnified observation. Women of childbearing age are recommended to have their cervix examined along with a physical examination. There is evidence that over 90% of cervical cancers can be effectively prevented by biennial screening, but in China today, only an estimated 5% of cervical cancers are currently prevented. Most experts recommend the following as to which women need cervical cytology screening and how often it should be done at intervals: 1. Cytology screening should be done at least every two years for those women with no cervical pathology and no history of disease. 2. All women who are sexually active should have regular cytology exams starting at age 18-20, or within one to two years after their first sexual encounter. 3. For women over 70 years of age, if they have had two regular cytology examinations with normal results within the last five years, they can stop regular examinations, but if they have never had a cytology examination or have volunteered for one, they should have a cytology examination. Other considerations: 1. The above applies only to women who have no suspicious symptoms or past medical history, and who have had abnormal results on a previous cytology test but have not been followed clinically. Women with suspicious symptoms or previous medical history should be managed according to the process of the consultation protocol. 2. Cytology is not required for women who have never had sex. 3. For women who started having sex before the age of 16, clinicians may start regular cytology examinations before the age of 18, depending on the situation. 4.Younger women (especially those under 30 years old) do not need to be examined frequently (e.g. once every six months) or have some additional DNA testing done, as it is not meaningful and not inexpensive. 5.Women who have been doing regular cytology examinations for a long time can stop the examinations at the age of 70. 6. For women with total hysterectomy, if the cervical part is not completely removed then regular cytology examination is needed; if there is a history of atypical cervical hyperplasia or malignant lesions, a vaginal vault smear is also needed. Late stage cancer is incurable. Early detection and early treatment of cancer can be curable. The worldwide mantra for cervical cancer is early detection and elimination of cervical cancer as early as possible with the assurance of a well-developed cervical cancer screening system. A few minutes of gynecological examination every year will keep you away from cervical cancer.
