Treatments for cervical pre-cancer (CIN) aim to remove or destroy the abnormal cells. Laser ablation, cold coagulation and cryotherapy treat the part of the cervix that contains abnormal cells, allowing normal cells to grow back in their place.

Cone biopsy, hysterectomy, LEEP (Loop Electrical Excision Procedure) and LLETZ (Large Loop Excision of the Transformation Zone) remove the whole area of the transformation zone – the area containing all the cells that could become precancerous or develop into cervical cancer.
