The main cause of CIN is the human papilloma virus (HPV). There are over 100 types of HPV. Some types can affect the cervix and cause the abnormal cell changes that may develop into cervical cancer. These types of HPV are called high-risk HPV.

Then, what is the difference between CIN 1 and CIN 2?

Low-grade neoplasia (CIN 1) refers to dysplasia that involves about one-third of the thickness of the epithelium. CIN 2 refers to abnormal changes in about one-third to two-thirds of the epithelial layer. CIN 3 (the most severe form) describes a condition that affects more than two-thirds of the epithelium.

Beside above, how long does it take CIN 1 to go away?

CIN-1 is due to infection with HPV (human papilloma virus). Of every 10 cases of HPV infection, eight will go away without treatment within 12 months. In addition to CIN changes, other minor abnormalities are commonly seen. These often need follow-up but do not necessarily mean that precancerous changes are developing.

Is Cin curable?

Most of the time, cases of CIN can be treated successfully. Ablation and resection are effective in about 90% of all cases, with a 10% chance of recurrence of CIN after treatment. It only rarely progresses to cancer, and when it does progress, it does so very slowly.
