The colposcopist will be looking for cells that appear cancerous or are showing pre-cancerous changes.
Pre-cancerous changes are known as ‘cervical intra-epithelial neoplasia’ or CIN. There are three grades of CIN. The grades describe how far the abnormal cells have gone into the surface layer of the cervix. With all three grades of CIN, often only a small part of the cervix is affected by abnormal changes.
Sometimes the abnormal cells are found in special mucus-producing tissue. These abnormal cells are called CGIN.
Neither CGIN or CIN mean that you have cancer, but if left untreated, these abnormal cells are at risk of developing into cancer over a long period of time in the future.
