Cervical biopsy is usually better done 3-7 days after menstruation, because the cervical biopsy is done just after menstruation, the relative cervical wound has a period of healing, to avoid the contamination of the wound or the wound causing endometriosis because of the onset of menstruation just after the cervical biopsy. Therefore, it is better to have a cervical biopsy 3-7 days after menstruation. However, if a woman’s cervical examination is particularly bad and she has cervical cancer, she can have a cervical biopsy at any time and it is not necessary to wait until 3-7 days after menstruation to have it, so as to avoid the spread of cervical cancer and losing the best time for surgery because of the long waiting for menstruation. Therefore, after biopsy, you can give some medicine to delay menstruation and wait for the pathology results to show back to give surgery in time.
