A cervical biopsy is usually done without fasting and needs to be performed by a medical professional. Cervical biopsy is a necessary step to identify pre-cancerous lesions of the cervix and cervical cancer, and needs to be performed by specialized doctors. It should be performed by a specialized doctor with clear indications, such as colposcopic examination for suspected cancer, visual examination for suspected cancer, etc. Contraindications such as acute inflammation of reproductive tract should be ruled out, and the procedure should be performed in strict aseptic condition. Because anesthesia is not required, fasting is not necessary for cervical biopsy. When taking cervical biopsy, the material should be taken from the most serious lesion area with biopsy forceps at multiple points or single point, and if necessary, cervical tube scraping should be carried out at the same time. After the operation, gauze should be stuffed locally in the cervix to stop bleeding by compression, and be taken out after 24 hours. After the cervical biopsy, we should pay attention to appropriate rest, prohibit sexual intercourse and pelvic bath for 2 weeks, observe the vaginal bleeding, and track the pathological results to give timely treatment.
