Cervical tissue biopsy is generally not recommended if the leukorrhea is abnormal. If the leukorrhea is abnormal, it means that there is local gynecological inflammation such as vaginitis, cervicitis, etc. At this time, it is not recommended to carry out colposcopic cervical tissue biopsy, because after the biopsy, the local area will be exposed to fresh wounds, and then the bacteria will easily attack the local area, which is not conducive to the healing of the wounds. For women who need to perform a cervical tissue biopsy, it is also important to note that the menstrual period should be avoided, because menstrual blood will also affect the healing of the wound, but also note that there will be a small amount of vaginal bleeding after the biopsy, pay attention to keep the vulva clean and hygienic, and prohibit sexual intercourse for 1 month after the biopsy. For patients who need to carry out cervical tissue biopsy, it is recommended that they go to the gynecology department of regular hospitals, under the guidance of doctors, standardized operation, so as not to lead to poor healing of the local wound.
