Generally speaking, CIN I has about 50% chance of reverting back to normal. CIN II and III are more likely to progress to cancer. It is hard to say how long it takes for cells to go from normal to CIN II or III and then to cancer. If the progression occurs at all, it is likely to happen in years, rather than weeks to months.
Usually, doctors would recommend treatment if a woman was found to have CIN II or CIN III. Treatment is in the form of day surgery. Effectively, one cuts out the affected small area so the cervix will not be at risk of cancerous changes.
To date, there is no proven medical treatment for CIN II or III in the form of tablets or topical cream. Women need to be very weary if they are offered such treatment with the promise of cure.
