Various cervical cancer screening methods have their own advantages, and the following common screening methods are briefly introduced: 1. Traditional cervical cytology smear (Pap smear) Screening method: Epithelial cells in the cervix and cervical canal are scraped with a gynecological bamboo scraper, evenly coated on a slide, and then fixed and stained. Due to the large human interference factors in the taking, production and reading of the film, the accuracy of the results is limited, this method is now gradually eliminated, and is still applied in areas with great economic difficulties. 2, liquid-based cytology test method (TCT) screening method: also known as the new Park’s thin-layer cytology test. It is a small brush to take the cells shed in the cervical canal in the preservation solution, and then the pathologist for the final diagnosis. Due to the unique method of sampling and production, which facilitates the detection rate of low-grade and high-grade cervical lesions, TCT has become a routine method for screening and detection of early lesions, and it is advocated that women over 20 years of age who are sexually active should undergo liquid-based cytology once a year. 3.Human papillomavirus (HPV) test Screening method: Blood is drawn to check for viral infection, while HPV-DNA genotyping test detects 23 specific types of HPV (high-risk or low-risk). The detection of high-risk HPV infection in women with normal cytology smears can also predict the risk of worsening cervical lesions or recurrence after surgery. This test both eliminates patient concerns and assists the physician in developing a correct and effective follow-up and treatment plan. 4.Colposcopy Examination method: After wiping off the surface of the cervix and vaginal secretions with a cotton swab, observe the surface of the cervix, then apply 3% acetic acid solution on the surface of the cervix for 30-60 seconds and then microscopically observe it, and finally perform the iodine solution test. Direct observation of the cervix through magnification rapidly identifies benign and malignant lesions and provides reliable biopsy sites, improving the accuracy of early diagnosis of cervical cancer. Colposcopy is used as a diagnostic tool for diagnosing early cytology or further examination after abnormal HPV testing, but not for screening.
