Cervical pre-cancer (cervical intraepithelial neoplasia) can be treated in different ways depending on the extent and nature of the disease. Less invasive treatments that do not require a hospital stay may be used. A general anaesthetic is occasionally needed, especially if the disease has spread locally, early invasion is suspected or previous out-patient treatment has failed. Surgery can be done with a knife, cryotherapy (freezing the abnormal cells), laser or cutting with a loop (an electrically charged wire). This review found there was not enough evidence to confidently select the most effective technique and that more research is needed.
