The main reason why cervical biopsy is done clinically is because there are local lesions in the cervix, and if the diagnosis cannot be confirmed clinically, it is necessary to biopsy the cervical tissue and send it for pathological examination, and the pathological diagnosis prevails clinically. Usually, if there is a problem with TCT test, or if there is high-risk HPV infection, or if there is contact bleeding in the clinic, or if there is cauliflower-like tissue material found locally in the cervix, the possibility of cervical cancer is suspected, so cervical biopsy should be done in these cases, and it should be done under the instruction of colposcopy. After cervical biopsy, it is important not to take a sitz bath or have intercourse for half a month. If there is an increase in vaginal bleeding, it must be treated in the hospital and the bleeding must be stopped by re-compressing the gauze in the vagina.
