A cervical biopsy usually takes about ten minutes. It is important to note that a routine leukorrhea test is required prior to the cervical biopsy and it is clinically recommended that the patient undergoes the cervical biopsy within 3 to 7 days of menstruation. Cervical biopsy is usually performed in four places, i.e., 3, 6, 9 and 12 o’clock, and the appropriate specimens are selected and sent to the Pathology Department for examination. In addition to the colposcopic procedures such as iodine test to select the biopsy tissue in the uncolored area and acetic acid white test to select the biopsy tissue, it is generally recommended to perform a multipoint biopsy to ensure accuracy. Cervical biopsy is an important method of diagnosing the presence of squamous intraepithelial lesions of the uterine cervix and cervical cancer, and is highly accurate.
