Cervical Screening

Cold coagulation

Cold Coagulation is used to treat abnormal cervical cells, which are also known as cervical intraepithelial (CIN), by destroying the affected area, so that normal cells can grow back in their place. It is usually performed in a hospital outpatient clinic, using a local anaesthetic. Most women need only one session of treatment. A biopsy (a sample of the skin) is required before cold coagulation treatment is used. The abnormal cells are removed by heating not freezing. A hot probe is used to destroy the abnormal cells. Women should not feel the heat of the probe, but may get a period type pain while being treated or for a short while afterwards.
We interviewed one woman who had cold coagulation treatment. Treatment was performed at the same time as she attended the colposcopy clinic for investigations following her abnormal screening test result.
