Likewise, can CIN 2 go away on its own?
Moderate cervical lesions -- formally known as cervical intra-epithelial neoplasia grade 2 (CIN2) -- are abnormal cells on the surface of the cervix. But some studies have suggested that CIN2 lesions often regress completely without treatment and should therefore be simply monitored instead.
Secondly, 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.
Moreover, how long does it take for CIN 2 to develop into cancer?
However, it is estimated that 5% of CIN 2 and 12% of CIN 3 cases will progress to invasive cancer if untreated. In general, it takes 10 to 20 years for CIN to progress to cancer, allowing a significant time period for detection and treatment. Progression from CIN to cancer requires persistent HPV infection.
How bad is cin2?
Introduction. High-grade cervical intraepithelial neoplasia (CIN) is considered a precursor lesion to the development of invasive cervical cancer 1. There is evidence that the risk for progression of a CIN2–3 lesion to microinvasive cancer is less than 10 % with estimated time intervals ranging from 10 to 25 years 3.
