Can cervical cancer be prevented According to worldwide statistics, the incidence of cervical cancer ranks second among female malignant tumors, and the incidence rate has been increasing year by year in recent years with a trend of youthfulness. There are about 470,000 new cases of cervical cancer in the world every year, and China is one of the regions with high incidence of cervical cancer, with an incidence rate of about 150,000, second only to Chile. The cervix is very convenient for clinical examination due to its special anatomical characteristics: most precancerous lesions that may develop into cervical cancer can be detected and treated at an early stage, therefore, among all cancers, cervical cancer is the easiest to prevent. What is the relationship between HPV infection and cervical cancer HPV, or human papillomavirus, is one of the most common sexually transmitted pathogenic microorganisms, with over 200 different types identified. The infection rate of women with a history of sexual intercourse is 80-85%, and the virus disappears naturally in 1-2 years in about 90% of the infected people. High-risk HPV categories: 16, 18, 33, 52, 53, 58, etc.; low-risk HPV: mainly causes benign lesions such as external genital warts and LSIL. categories: 6, 11, 42, 43, 44, 81, etc. Who needs to be screened for cervical cancer and precancerous lesions All women with a history of sexual intercourse should be screened for cervical cancer. High-risk women population, including women with multiple sexual partners, premature sex, HIV/HPV infection, immunocompromised, poor hygiene/lack of sexual health knowledge, and history of cervical lesions. What is the difference between MCT and Pap smear MCT, i.e. thin layer liquid-based cytology, is one of the most advanced cervical cytology detection techniques in the world, which is the most basic and effective method for cervical cancer screening by examining cervical exfoliated cells for the purpose of screening early cervical cancer. MCT has now replaced the traditional Pap smear and has significantly improved the detection rate of cervical lesions. Colposcopy Colposcopy is a magnifying endoscope between the naked eye and the low power microscope. It can visually observe not only the small changes in the morphology of the vulva, vagina and cervix, but also the vascular and epithelial changes of the cervix with the help of green light, acetic acid test and Lugol iodine test, which is of great significance for the early detection of cervical cancer and precancerous lesions. The examiner needs to be professionally trained and have rich clinical experience.
