What are the precautions for optical colposcopy examination

1. Do not use lubricant when placing a vaginal speculum. The vaginal dilator should be inserted while expanding under direct vision to avoid scratching the cervix.
2. Individuals with suspicious lesions should undergo biopsy under colposcopy.
3. Fully expose the cervical canal to avoid missed diagnosis, and pay attention to those who move within the transition zone.
4. The selection of examination time: there is no time limit for suspecting cervical cancer or cervical intraepithelial neoplasia. Understanding cervical intraductal lesions should be close to ovulation or ovulation, while other diseases should be within 2 weeks after menstruation is complete.
5. Vaginoscopy examination cannot determine the pathological tissue examination.
6. The combination of colposcopy and cytology can reduce the missed diagnosis rate.
