Iron Cervical scraping can generally detect cervical cancer and is an important means of screening for cervical cancer and precancerous lesions. Cervical scraping mainly uses a microscope to observe whether there are abnormalities in cervical exfoliated cells, which can detect cervical intraepithelial neoplasia or cervical cancer early. However, the confirmed diagnosis needs to be combined with the results of HPV testing, colposcopy or pathological biopsy.
The accuracy of cervical smears depends on a variety of factors. Brushing cervical canal and transitional zone cells during sampling can increase the detection rate. If only superficial cells are collected, diagnosis may be missed. For low-grade squamous intraepithelial lesions, the detection rate of scraping is about 70-80%, while the detection rate of high-grade lesions can reach more than 90%. Postmenopausal women may experience insufficient sampling due to cervical atrophy and inward migration of the transition zone. Inflammation, bleeding or irregular operation can also affect the reliability of the results. It is recommended to conduct the examination 3-7 days after menstruation is clear to avoid vaginal douching or medication interference.
Liquid-based cytology technology can reduce blood and mucus interference and improve cell preservation quality. Traditional Pap smears may cause misdiagnosis due to cell accumulation, dryness and deformation. Repeated cervical scraping examinations can dynamically observe cell changes, which is particularly important for those with persistent HPV infection but negative initial scraping. If the scraping report shows atypical squamous cells of unknown significance, a reexamination is required after 3-6 months. If low-grade lesions are found, follow-up is recommended for 6-12 months, and high-grade lesions require immediate referral for colposcopy.
It is recommended that sexually active women over the age of 21 undergo cervical scraping screening every 3 years, and HPV testing can be extended to 5 years over the age of 30. People over 65 years old who have three consecutive normal results can stop screening. Regular check-ups are still required after vaccination with HPV, and any abnormal vaginal bleeding or discharge should be sought by a doctor promptly. Healthy habits such as maintaining a single sexual partner, using condoms, and avoiding smoking can reduce your risk.
