Colposcopic biopsy can detect cancer, it is a test that involves multi-point biopsy of the cervix under the colposcope, and cervical cancer can be diagnosed through this test. The colposcopic biopsy will use biopsy forceps to take small pieces of tissues, usually 3-4 pieces of tissues should be clamped and sent for examination, and then according to the cellular anisotropy and tissue anisotropy under the microscope, it will be judged whether there is pre-cancerous lesion of the cervix or cervical cancer. The order of choice for colposcopic biopsy examination is generally, for women who are sexually active to have regular cervical cytology and HPV testing as a screening for cervical lesions; if there is an abnormality in cervical cytology or HPV testing, further colposcopic cervical multiple-point biopsy should be performed as a confirmatory examination.
