Lipknife is commonly used to treat precancerous lesions of the cervix, which has the function of fast surgery, less bleeding and hemostasis. The disadvantage is that the electrodes may carbonize the edges of the incision, which may have an impact on the pathological results, and regular review should be performed after Lipknife treatment. Lipknife treatment itself does not cause cancer. Cancer refers to the anomalous change of normal cells, but there is no guarantee that cancer will not occur in the future. Cancer is the developmental change of the cervical disease itself. Lipknife, also called cervical electrothermal coil loop excision, is mainly for the treatment of cervical precancerous lesions, which is to remove precancerous lesions to prevent cancerous changes. Lipknife is a high frequency electromagnetic wave generated by the electrode tip, which produces a relatively powerful energy to the lesion. The surgical method is less damaging, quicker to recover, does not require hospitalization, does not affect the normal tissue of the cervix, and does not cause cancerous changes.
