If you are found to have cell changes that may lead to cancer, your treatment will depend on the level of changes. CIN I changes have a 50% chance of reverting back to normal, whereas CIN II and III changes are more likely to progress to cancer. This progression, if it occurs at all, is likely to happen over a period of years. Treatment for women with CIN II or III involves removing the small affected area of the cervix in a simple day surgery procedure. There is no proven medical treatment in the form of tablets or topical creams.
