Although colposcopic cervical biopsy is somewhat invasive, it generally has no effect on the body unless a traumatic infection or heavy bleeding from the trauma occurs. Cervical biopsy is generally based on screening of the cervix. If the results of TCT and cervical HPV tests show abnormalities, a portion of the tissue is further taken under colposcopy and sent for pathologic examination. Biopsy is usually performed about 3 days after menstrual cleansing, and coitus is not allowed within 2 weeks after biopsy, because sexual intercourse is prone to traumatic infection, traumatic bleeding, etc., and in severe cases, it may lead to acute cervicitis, poor healing of local wounds, or even retrograde uterine cavity or fallopian tube infections. If colposcopic cervical biopsy is necessary, you should go to the hospital to consult a professional doctor, and after the operation, you should follow the doctor’s instructions to do the precautions.
